Combo

The Combo module is the most complete expander in the range and allows to configure the following: 1 universal analogue input (tension/current/temp.probe). 1 analogue input in tension or current. 2 analogue outputs. 3 digital inputs. 3 digital outputs one solid state and two relay

The expander communicates through Modbus Protocol on RS-485
