8AI2DO | GC5

S series

The SFAR-S series of I/O is the generation of the modules for the industrial automation and robotics. There are 12 different types with the range of built-in I/O  from 6 to 16, which makes these modules very cost effective solution. Built-in RS485 interface allows to easy connection over Modbus RTU/ASCII protocol with a PLC makes the modules an external I/O. To simplify installation the modules have been equipped with Quick Connector system.

8AI2DO

The module has 8x AI (Analog Inputs) and 2x DO (Digital Outputs). AI can work in 7 modes as voltage or current input. DO is an NPN type open collector output with maximum load 500 mA, 55 V DC. All inputs and outputs are isolated from the logic with use of optoisolators. 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.

To simplify installation the modules have been equipped with Quick Connector system. Using dedicated SFAR-S-LINK cable allows to connect up to 15 modules which provide both RS485 communication and power supply.
