Logic Or Counter Inputs Module

Module of logic inputs
The SM3 module of two logic inputs is destined to collect logic states of logic inputs and make them accessible to computer-based industrial systems working on the base of the RS-485 interface. The module has 2 logic inputs and RS-485 interface with MODBUS RTU and ASCII transmission protocols. RS-485 and RS-232 ports are galvanically isolated from input signals and supply. The module programming is possible by means of the RS-485 or RS-232 port. In the SM3 module set there is a connecting cable to connect with the PC computer (RS-232).

Module as an impulse converter
The SM3 module working as an impulse converter is destined to add measuring devices equipped with impulse inputs, e.g. watt-hour meters, heat-meters, gas-meters, flow transducers a.s.l., to computer systems. Then, the SM3 converter enables the remote readout of the counter state in automatized accounting systems. The converter has 2 impulse inputs and RS-485 interface with MODBUS RTU and ASCII transmission protocols, what enables its application in computer systems with LUMEL-3000, Wizcon, Fix, In Touch, Genesis 32 (Iconics) and other visualization programs.
