The SM3 module is destined to collect logic states or to count pulses coming from the inputs and make them available to computerized systems working on the base of RS-485 interface.
The SM3 module has 2 logic or pulse inputs and RS-485 interface with MODBUS RTU and ASCII transmission protocols. The programming of the modules is possible using RS-485 or RS-232 interface and LPConfig software.
Module parameters:
The SM1 - 2 channels module of analogue inputs is destined to convert standard signals, resistance or temperature signals into numerical data accessible through the RS-485 or RS-232 port by means of the MODBUS protocol.
