MW241 Small I/O module for control of LED lights and sunblinds

Triac power amplifier

MW241 is a small I/O module featuring 2 DI and 2 DO (solid state relays). It is used for control of two lighting groups (using switches or buttons) or as a simple I/O module with no embedded bindings between inputs and outputs – the logical functionality is implemented in a master PLC.

  • Control of two lighting groups, with override from a PLC or SCADA over the bus 
  • Control of a blind 
  • I/O module 2×DI, 2×DO for general use 
     
In a plastic casing suitable for monting into a flush box there is a board with terminals, and other components. As the device is energized the the outputs set into predefined states and then are controlled either by input signals, or by bus commands, or by combination of both. Priorities may be set: the outputs permanently copy the states of the inputs (local control), or change their states as input states change (the last command is valid), with optional override over the bus.
 
It is also possible to set the function of bus override: relays are updated either at each change of the bus command, or at each bus command, or permanently with no regards of bus commands frequency. See details in the Modbus map domat-int.com/en/downloads/technical-documentation/modbus-tables
