MOD-IO9 and MOD-IO9-AI have been designed to be a compact wall mounted Modbus RTU input and output modules.

The module has 2 volt-free digital inputs for measurements e.g. for windows, occupancy sensors and so on. The module has 2 digital outputs, 24Vac triacs switching the plant items on/off. The IO9 modules has 2 inputs for measuring NTC10 temperature, resistive measurements (e.g. light level) or volt-free on/off signals.

The IO9-AI models have 2 inputs for measuring 0..10Vdc signals. The three analogue 0..10Vdc outputs complete the compact IO-modules. With the analogue outputs it is possible to control zone valves and other modulating plant equipment.

The units support Modbus RTU RS-485 communication (Modbus slaves), and parameters are available using Coils, Discrete Inputs, Input Registers and Holding registers.
