Configurable Inputs: Can be individually configured as Digital, 4-20mA, 0-10VDC or 10K thermistor.

When set to Digital the inputs can be used to monitor and count pulsed signals from multi utility meters such as electricity, gas and water, or fault/ status signals from 3rd party equipment.

When set to the analogue ranges, the inputs can be used to monitor standard sensors such as temperature, humidity and light level.

Digital Inputs: Can be used to monitor and count pulsed signals from multi utility meters such as electricity, gas and water, or fault/ status signals from 3rd party equipment.

Digital Outputs: Can be used to control equipment and machinery by switching external contactors or relays.

Analogue Outputs: Can be used to control 3rd party equipment which requires a 0-10V signal, such as set-point control on AC, ventilation equipment, valves and boilers.
