Purpose and Description of the Module
The SfAR-1M-4DO module is an innovative device that provides a simple and cost-effective extension of the number of outputs in popular PLCs.
This module is connected to the RS485 bus with a twisted-pair wire. Communication is via Modbus RTU or Modbus ASCII. The use of 32-bit ARM core processor provides fast processing and quick communication. The baud rate is configurable from 2400 to 115200.
The module is designed for mounting on a DIN rail in accordance with DIN EN 5002.
The module is equipped with a set of LEDs to indicate the status of inputs and outputs which is useful for diagnostic purposes and helping to find errors.
Module configuration is done via USB by using a dedicated computer program. It also allows for changing the parameters using the Modbus protocol.
