MODBUS Interface Module

MODBUS Interface Modules connects to the RS-485 peripheral bus of the ZX series fire alarm control panels and allows panel interrogation by Modbus control system.

MODBUS interface module consists of a circuit card mounted on a steel plate within a polycarbonate IP67 rated enclosure, as shown above. Pre-pressed knock-outs on the box sides allow cable entry glands to be fitted for power and communication line wiring. A DC supply in the range of 18-28V DC, typically 24V DC, rated at 150 mA, is required to power the interface, An on board switch mode power supply isolates this input from all communication circuitry.

Features & Benefits:
  • Modbus protocol supported
  • IP67 rated enclosure
  • Integrates seemlessly with ZX control panels
  • RS232 third party data port
