Key Features for Industrial Environments
Optical Precision
Utilizes advanced light-scattering photoelectric technology for early smoke detection, offering vastly superior sensitivity to smoldering fires over older ionization types.
OT/IT Energy Efficiency
With an alarm draw of just ≤ 1.8mA, this detector allows engineers to daisy-chain multiple units on a single 24V DC power rail without causing voltage drops in the control cabinet.
Rugged Durability
Equipped with an ExiaIICT5 rating, the housing is designed to withstand harsh shop-floor conditions, dust interference, and temperature fluctuations.
PLC & SCADA Integration Guidelines
Unlike standalone residential alarms, the JTY-GD-G3/G3T acts as a vital edge sensor in a Smart Factory ecosystem.
Direct PLC Wiring
The detector integrates seamlessly with standard PLC Digital Input (DI) modules. By utilizing the 24V DC interface, automation engineers can configure the PLC logic to:
- Trigger immediate automated shutdown sequences for conveyors or CNC machines in the affected zone.
- Activate specific relays to control ventilation dampers and exhaust fans.
- Log timestamped alarm data directly into the MES or SCADA historical database for safety compliance auditing.
