CM-20

The CM-20 is a programmable control unit designed to operate with one or two 4-20 mA gas detectors. It is supplied in a wall-mounted enclosure. Straightforward programming via push buttons and an alphanumeric display allows alarm and pre-alarm set points to be defined for each detector. Front-panel LEDs and a buzzer summarise the status of the system (alarm and fault). The configuration software simplifies the set-up and commissioning of the CM-20. An extensive library of configurations makes it easy to get started. Custom messages can be configured.

RS485 interface boards

The REM-485-T0 is an optional module for CM-80 control panels. It provides 12 SPST relays rated 5 A/30 VDC and is also available in an ABS enclosure (240 x 191 x 107 mm) under the reference REM-485-T0-B. It connects to the control panel over an RS485 Modbus RTU serial link (or CAN bus). The status of the board is indicated by LEDs (power present, status of the 12 relays, Tx/Rx communication channels). Connections are made on pluggable terminals.
