Universal 8-Output and 12-Input Control Board via RS485 and Modbus RTU
SKU: MD20004
EAN: 5902186335813
The MODIG Modbus RTU 8 OUT / 12 IN module is equipped with 8 electromagnetic SPDT relays and 12 galvanically isolated inputs. All outputs and inputs are controlled and read via standard Modbus commands transmitted through an RS485 interface. The control interface features robust galvanic isolation and surge protection, ensuring stable and reliable operation even in installations exposed to severe electromagnetic interference. Both communication parameters and operational functionalities of the module can be flexibly configured to meet the specific requirements of various applications.
