The EX-A41 expansion module is a versatile solution that allows the expansion of telemetry modules to handle additional analog input/output signals. The device features a compact design, making it ideal for installation in spaces with limited room. Its industrial enclosure with a DIN rail mounting system enables easy installation in control cabinets. The detachable screw terminal blocks ensure secure and reliable signal connections and make connections easy without needing specialized tools.

The expander is equipped with four galvanically isolated analog inputs (4-20 mA) and one analog output (4-20 mA). The EX-A41 module can communicate with any Master/Client device supporting Modbus RTU or Modbus TCP standards, ensuring broad compatibility with various systems and devices, not only from the family of telemetry modules. A key advantage of this solution is its ability to be remotely configured and updated via the Ethernet interface.
