MODBUS Module: Converts 4-20 mA signal to MODBUS.
MODBUS Panel: Retrofit control panel allowing MODBUS controls
CORUS involvement in the design
- Proposed design that can fit into the back of a family of gas detection products that takes the 4-20 mA signal and converts it into a MODBUS signal. Design allows access to the relays on the gas detector.
- Firmware upgrades on detector and panel allow for automatic detector identification.
- Daughter PCBA on panel allows for MODBUS communication over serial port.
- Addition of addressable MODBUS communication expands panel capacity from 12 analog to 99 sensors – 12 analog and 87 MODBUS.
