SFAR-1M-1TI1DO

Modbus I/O module with 1 temperature input and 1 digital output.

Modbus I/O Module
SfAR-1M-1TI1DO is designed for controlling ON/OFF heaters following temperature measurement.

1 Temperature Input & 1 Digital Output
The module has 1 temperature input (TI) and 1 digital output (DO). A temperature input can work with the most popular resistance temperature sensors and a wide range of thermocouples. A digital output is a NPN transistor output. All inputs and outputs are isolated from the logic with optoisolators.

Simplified Configuration and Commissioning Process
A built-in RS485 interface allows an easy connection over the Modbus RTU/ASCII protocol. A 32-bit ARM core processor provides fast processing and communication.
The module is equipped with a set of LEDs used to indicate the status of I/Os, power supply, and RS485 communication.
Configuration of the module is carried out with our free software, the SfAR Configurator. A built-in mini USB allows for performing a primary configuration of the unit without an additional power supply.
