    Description

    SM4, RS-485 MODBUS Module with Logic Outputs

    The SM4 module with logic outputs from LUMEL is destined to control simple actuators through assignment of logic states received from the master device through the RS-485 interface.
    The module can have 8 logic outputs or 4 relay outputs (please select when ordering!) and RS-485 and RS-232 interfaces with MODBUS RTU and ASCII transmission protocols.
    The RS-232 and RS-485 ports are galvanically isolated from output signals and the supply voltage.
    The module programming is possible by means of the RS-485 or RS-232 port through the free LPConfig software.
    An interface cable†to connect the module with a computer (RS-232) is included to the SM4 module set.


    Module parameters:
    • 8 outputs of OC type or 4 relay outputs,†
    • RS-485 communication interface with MODBUS RTU and ASCII transmission protocols to work in industrial systems with an optical transmission signalling on LEDs
    • Configurable baud rate: 2400, 4800, 9600, 19200, 38400, 57600, 115200 bits/s
