Goodsky 822UA-1C-C — 24VDC 30A Power Relay (5 pcs)

Goodsky · 822 Series · 1 Form C (SPDT) · In stock

The Goodsky 822UA-1C-C (CAR-SH-124DU) is a heavy-duty T-shape PCB / plug-in power relay rated 30 A at 250 VAC / 30 VDC with a 24 VDC coil. Manufactured by Goodsky (Taiwan Goodsky Electric Co.) — one of Asia’s most established relay brands — it ships as a 5-piece pack for prototyping, panel building and field service. Sourced by KOEED alongside Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic and KEYENCE spares for one-stop BOM quotation.

Key Technical Specifications

Application Scenarios & Where It Fits

The 30 A contact envelope and 24 VDC coil put the 822UA-1C-C in the sweet spot for mid-current switching in industrial automation panels. It is widely used as a logic-to-power interface relay, complementing PLC outputs from Allen-Bradley CompactLogix or Siemens S7-1200 systems, and as a driver relay for motor contactors from Schneider TeSys or Mitsubishi S-N series.

• HVAC rooftop units, AHU fan stages and compressor control boards
• Vending machines, coffee makers, commercial refrigeration defrost timers
• Commercial washing machines, dryers, dishwashers and laundry control panels
• UPS and inverter switch-mode power supplies where a 30 A relay is used for bypass / transfer switching
• Welding and plasma-cut equipment, machine-tool spindle coolant pumps
• EV charging stations and battery management contactor pre-drivers
• Factory automation relay-logic interposing panels alongside Omron MY2N or Yaskawa drive I/O boards
• Fanuc and Panasonic robotic cell safety / E-stop interlock chains
• Vision-guided inspection stations that pair the relay with a KEYENCE CV-5000 trigger output

Integration & Wiring Notes

Reading the suffix helps: “UA” denotes the T-shape 822 case and contact family; “1C” means 1 pole, Form C (SPDT) — one common, one normally-open, one normally-closed; the trailing “C” indicates a silver-alloy contact. The order code CAR-SH-124DU decodes as: CAR = CAR-truck family, SH = sealed dust cover, 124 = 24 VDC coil, DU = Form C SPDT.

• Coil pins: A1 (+) and A2 (−) accept 24 VDC. The coil is not internally suppressed — add a flyback diode (1N4007 reverse-biased) if driven directly by a Panasonic FP-X or Omron CP1H transistor output.
• Contact pins: COM (common), NO (normally open) and NC (normally closed) on the load side. The silver-alloy contacts handle inrush well; for capacitive loads (SMPS, EV chargers), add an RC snubber or a varistor (MOV) across the contact to suppress arcing.
• Socket option: Use a 822-series compatible 5-pin PCB socket or DIN-rail socket so the relay can be swapped without desoldering — convenient for field service on Siemens or Allen-Bradley retrofit panels.
• Footprint: Standard 5-pin T-shape pitch (~5 mm). Maintain 10 mm clearance around the relay body to keep the contact temperature inside its rated 85 °C ceiling.
• Driving a contactor: Wire the 30 A contact in series with the coil of a Schneider LC1D or Mitsubishi S-N20 contactor when switching motors above 30 A.

Installation & Commissioning Tips

Even a robust relay like the Goodsky 822UA-1C-C will fail prematurely if it is wired, mounted or driven outside its envelope. The following tips come from field service on Yaskawa servo cabinets, CNC panels and OEM machine builds.

• Polarity: Observe A1/A2 polarity. Reversed polarity on the DC coil can cause weak pull-in and contact welding under heavy inrush.
• PCB soldering: Hand-solder at 340 °C max with a 3 s dwell to avoid plastic-case deformation. Use a socket when the relay will be replaced more than once in the panel’s life.
• Snubber sizing: For 230 VAC motor loads, a 0.1 µF + 100 Ω RC snubber across the contact extends electrical life 3–5×.
• Surge on the coil: A reversed-biode (1N4007) or a 36 V TVS across A1/A2 is strongly recommended when the coil is driven by a KEYENCE or Omron transistor output.
• Mounting orientation: Prefer vertical (contact terminals down). If the relay is mounted horizontally, derate the contact current by ~15 % because of convection loss.
• Pre-commissioning check: With the panel unpowered, measure coil resistance (should be ~640 Ω for 24 VDC). With power on, verify pickup voltage (~18 V) and dropout voltage (~2.4 V) before connecting the load.

Procurement, Warranty & Lead Time

KOEED is an independent multi-brand industrial-automation distributor — not a Goodsky subsidiary — so we can place the 822UA-1C-C alongside Allen-Bradley PLCs, Siemens HMIs and Mitsubishi inverters on a single BOM, with one invoice and one shipment.

• MOQ: 1 pack (5 pcs) for samples and field service; volume pricing tiers at 20 / 100 / 500 pcs.
• Lead time: Pack-of-5 typically in stock; OEM quantities quoted within 24 hours via Moritta@KOEED.COM.
• Warranty: 12-month replacement warranty against manufacturing defect, backed by our China Sourcing Company QC flow.
• Worldwide shipping: DHL / FedEx / UPS, with full export documentation. See the shipping policy for cut-off times.
• Authentication: Each lot traceable to Goodsky production batch. Tested for coil resistance, contact bounce and dielectric strength before despatch.
• Hard-to-find sourcing: Need an EOL or obsolete Goodsky part alongside a Fanuc A06B servo? Recent shipments show the kind of BOMs we already cover.

Need a matching 822-series socket, a DIN-rail base, or the full BOM for a control panel rebuild? Send the part list to Moritta@KOEED.COM and we will reply with availability and price within 24 hours on business days.
