SM4 - Modbus Logic Output Module

The SM4 logic output module is designed to control devices , final control elements which have been assigned a logic status. Control commands are recieved via RS-485 from a master device (EG SMC).The SM4 module has 8 OC outputs or 4 relays (depending on the ordering code) and the RS-485 interface with MODBUS RTU and ASCII transmission protocols. Programming of the module is achieved using an RS-485 or RS-232 interface in conjunction with LPConfig software.
 
Output: 8 outputs of OC type or 4 relay outputs
Communication: RS-485 MODBUS RTU and ASCII protocols, configurable baud rate:2400, 4800, 9600, 19200, 38400, 57600, 115200 bits/s
Programming interface: Frontal plate RJ connection (RS232)

Dimensions: 45 x 120 x 100mm
PLC SM4 logic output module Modbus rs485
