Beijer ST-2744 Digital output module

  • 4 relay outputs
  • Max 250 VAC
  • 2.0 A

  • Brand: BEIJER
  • Product Code: ST-2744


The FnIO S series is a micro modular remote IO-system from Crevis, which contains a wide selection of digital and analog modules as well as special modules. Together with a selected bus/ node module, the system is easily combined to make standalone IO-nodes.

The IO-system, which has an IP20 enclosure, is installed on a standard 35 mm DIN rail. Stable communication between the modules in the node is guaranteed via a unique sliding contact system.

A standard IO module is only 12 mm in width, and when using 16 channel IO modules a complete node is made up of 64 IOs of only 90 mm in width.

The FnIO S series supports known bus systems such as Profibus DP/V1, CC-Link, CANopen, Modbus-TCP, Modbus-RS232, and Modbus-RS485.
