Digital Inputs) and then, based on these inputs, control the system behaviour (activates or de-activates
outputs of the controller).
The system image is made available to external clients by means of the RS-485 digital link with the MODBUS
protocol. The serial communication enables connection to external automation systems or mimic panels.
1.3 Device characteristics
Basic functionalists
handling up to 32 gas detectors,
8 relays outputs,
4 binary inputs,
presentation of the gas detectors status (operation, exceeding the thresholds, its special
conditions and diagnostic status) – only Sigma MOD LED,
presentation of historical states (exceeding the thresholds, failures) – only Sigma MOD LED,
presentation of the relays status – only Sigma MOD DO,
control of the entire system operation.
The control unit module is designed to work with:
Line 4.0 Gas Detectors,
Control Unit Module Sigma MOD DRV,
other devices compatible with the built-in input-output interfaces.
Control Unit Modules Sigma MOD LED and Sigma MOD DO are designed for installation in
control rooms, inside control cabinets and other locations inside buildings. They are not
suitable for operation is potentially explosive atmospheres.
Control Unit Modules Sigma MOD LED and Sigma MOD DO offer vast opportunities of
configuration. However, to simplify understanding of this manual, many functionalities are
described based on the default configuration.
