2DI2DO | GC5

1M series

The SFAR-1M series of I/O modules is the generation of the devices for the industrial automation and robotics. There are 7 different types with the range of built-in I/O  from 2 to 4, which makes these modules perfect solution for measuring a small number of signals at one point. Built-in RS485 interface allows to easy connection over Modbus RTU/ASCII protocol with a PLC makes the modules an external I/O.

2DI2DO

The module has 2x DI (Digital Inputs) and 2x DO (Digital Outputs). DI can work as fast pulse counter up to 1 kHz and support PNP or NPN input types. DO are PNP transistor outputs with maximum load 250 mA, 55 V DC. Built-in RS485 interface allows to easy connection over Modbus RTU/ASCII protocol with a PLC makes the modules an external I/O. The use of 32-bit ARM core processor provides fast processing and communication with the baud rate from 2400 to 115200 bps. The module is equipped with a set of LEDs used to indicate the status of inputs, outputs, power supply and RS485 communication. This feature is useful for diagnostic purposes and helping to find errors.

Built-in mini USB allows for initial configuration of the unit without power supply.
