BKC TMG-N7000 Temperature Controller — Multi-Input PID Process Controller, 96×96mm Panel

BKC · TMG-N7000 · Digital Temperature / Process Controller · In stock

The BKC TMG-N7000 is an advanced digital temperature and process controller from Chinese OEM BKC, designed as a cost-effective alternative or direct replacement for legacy controllers used across factory automation and process-control lines. It accepts a wide range of inputs — thermocouple (J / K / R / S / B / E / T / N), RTD (Pt100 / Cu50), and analog (0–10 V / 4–20 mA / mV) — and drives relay, SSR driver and 4–20 mA re-transmission outputs from a single 96×96 mm DIN panel cutout. Engineers deploying Siemens or Allen-Bradley PLC backbones can use the TMG-N7000 as a local loop controller and integrate it over RS-485 Modbus RTU for SCADA visibility, recipe download, and remote tuning.

This listing is for 1 piece of the BKC TMG-N7000 with multi-input board, PID auto-tune, fuzzy logic, and ramp / soak program control. Whether you are maintaining a plastic extruder, a food-grade pasteurization line, or a laboratory autoclave, the TMG-N7000 is built to slot into a 96×96 mm panel cutout and start controlling temperature within minutes.

1. Key Technical Specifications

2. Application Scenarios — Where the TMG-N7000 Fits

The BKC TMG-N7000 is a general-purpose loop controller. It is commonly deployed wherever a single-zone temperature (or other process variable such as pressure, flow, or level via 4–20 mA) must be held to a tight setpoint — typically with PID auto-tune to remove manual loop-shaping. The multi-input board and SSR driver make it a drop-in fit for OEM machines, retrofits, and pilot lines across the process industries.

• Plastic & rubber processing: injection-mold heater zones, extruder barrel / die / mold temperature, hot-melt adhesive tanks.
• Food & beverage: cooking kettles, batch pasteurizers, CIP loops, chocolate tempering, brewing / fermenting vessel jackets.
• Ovens, kilns & furnaces: batch heat-treatment ovens, ceramic kilns, laboratory muffle furnaces, vacuum brazing furnaces.
• Pharma & laboratory: autoclaves / sterilizers, stability chambers, incubator baths, bioreactor temperature loops.
• Semiconductor & electronics: hot-plate preheaters, solder reflow zones, wafer-chuck temperature control.
• Packaging & converting: hot-roll laminators, heat-seal bars, shrink-tunnel zones, hot-air shrink lines.
• HVAC / building services: cleanroom hot-water loops, AHU heating coils, datacenter inlet temperature control.
• Process lines back-boned by major PLCs: supervisory Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic or KEYENCE PLCs reading PV / SV over RS-485 Modbus from the TMG-N7000.

3. Integration & Wiring Notes

Sensor wiring. Thermocouple inputs use the dedicated TC terminals at the rear and must be wired with the correct compensating cable; do not run TC extension wire alongside power cables. Pt100 / Cu50 RTD wiring should be 3-wire for best accuracy — if the sensor lead is short, a 2-wire shorting link can be added at the terminals, but expect reduced accuracy. For 4–20 mA / 0–10 V analog inputs from a transmitter, use shielded twisted pair with the shield grounded at one end only.

Output wiring. The relay output is rated for resistive loads only — when switching a contactor, solenoid or heater contactor, add an RC snubber across the coil. The SSR driver is a low-voltage DC pulse suitable for solid-state relays; size the SSR to the heater current. The 4–20 mA re-transmission output can be wired to a chart recorder, remote indicator, or directly into an analog input on a Allen-Bradley / Siemens / Schneider I/O module to surface the same PV to the SCADA layer.

RS-485 Modbus wiring. Use a daisy-chained shielded twisted pair (Belden 3106A or equivalent), terminate both ends with 120 &Omega resistors, and assign a unique slave address (1–247) to each TMG-N7000 on the trunk. Default register map typically exposes PV (0x0000), SV (0x0001), MV% (0x0002), run/stop (0x0004) and alarm status (0x0005) — refer to the BKC Modbus register sheet for the exact layout of your firmware revision. You can validate frames on the KOEED Modbus CRC Calculator before commissioning.

Power & grounding. The 100–240 V AC supply should be fed from a dedicated breaker with an EMC line filter upstream of the panel. Earth the controller chassis to the cabinet ground bus with a short, low-impedance braid. For 24 V DC cabinet installations, dimension the PSU to cover the controller plus its SSR loads' holding current.

4. Installation & Commissioning Tips

Panel cutout. Cut a clean 92×92 mm (or 96×96 mm per manufacturer spec) hole in the cabinet door, slide the controller in from the front, and lock the side mounting brackets. Do not over-tighten — plastic bezel threads can crack and will compromise the IP seal. Keep at least 50 mm clearance above and below for ventilation.

First power-up. Apply power and check that the PV shows the ambient thermocouple / RTD reading correctly. If you see "Sbr" (sensor break), the input wiring or sensor type selection is wrong. Set the input type code (e.g. 0 for K-type TC) in the parameter menu before connecting a sensor. Confirm decimal-point position and engineering unit (°C vs °F) match your process.

Auto-tune. With the heater wired and the process at ambient, enter the target setpoint and trigger the AT (auto-tune) function from the front panel. The controller will run a few on-off cycles, calculate P / I / D terms and store them. For processes with long thermal lag (large ovens, autoclaves), allow the AT cycle to complete undisturbed — it can take 10–30 minutes. After AT, verify the MV% response to a small setpoint step before committing to production.

Program / ramp-soak. For batch profiles (e.g. food cook curves, heat-treat recipes), use the multi-segment program mode: define ramp rate, soak time and target SV per segment. Up to 30 segments are typical. Recipes can be uploaded / downloaded over RS-485, which is useful when standardising collections of identical ovens across multiple lines.

Troubleshooting tools. When commissioning, use the KOEED PLC Error Code Database if the controller posts a fault, the PLC Hex to Float Converter to decode any Modbus register values that look off, and the PLC Analog Calculator to translate the 4–20 mA re-transmission back to engineering units. For end-of-life or hard-to-find replacements, the AI Diagnostic Tool can suggest cross-references to alternative controller models.

5. Procurement, Warranty & Lead Time

Each BKC TMG-N7000 ships brand-new in the original factory box with mounting brackets and a printed English datasheet. Standard KOEED warranty terms apply: every unit is bench-checked before dispatch, and worldwide shipping is available via DHL / FedEx / UPS with full commercial invoice, packing list and, on request, a China Sourcing Company QC report. Because KOEED is a multi-brand distributor (not the OEM), final warranty handling is coordinated through our service team — not through BKC directly.

Lead time. Single-piece and small-quantity orders are typically shipped within 2–3 business days from our Shenzhen / Hong Kong warehouse. Bulk orders (50+ pieces) usually require 7–15 business days depending on configuration; confirm via email. Pricing follows our standard B2B RFQ model — no public list price is published on the product page — so the final unit price is set in the quote returned to you. See the FAQs for how KOEED structures quotes, payment terms (T/T, PayPal, Alibaba Trade Assurance) and shipment Incoterms (EXW, FOB Shenzhen, CIF, DAP).

How to order. The fastest path is to send the exact model code (TMG-N7000), the quantity, your delivery country and any optional accessories (SSR, mounting brackets, RS-485 isolator) to Moritta@KOEED.COM. For multi-line BOMs, use the Create a Quote form — you can list controllers, sensors, and Siemens / Allen-Bradley / Mitsubishi / Omron / Fanuc / Schneider / Yaskawa / Panasonic / KEYENCE PLC parts in the same submission, and KOEED will return a single consolidated quote within 24 hours on business days.
