8x Universal Inputs : Universal inputs are compatible with

• passive sensors (Pt1000, NTC),
• active sensors (0-10Vdc)
• voltage-free contacts (DI)

See the datasheet for allowed types on each input.

4x Modulating Outputs : 0-10VDC analog outputs allow controlling modulating actuators.

Two of these points can be configured to function as digital inputs!

Real-Time-Clock

R/TIO modules host a battery backed-up real-time-clock. When used with Ontrol's touch-screen wall modules, weekly time schedules can be implemented that are fully configurable from the connected wall module or remotely from a supervisory system.

5x Relay Outputs : Five relay outputs are provided, each with 5A rating.

2x Triac Outputs : Flexible configuration options are provided, allowing control of on/off, thermo-electric (PWM) or floating actuators. The triacs can also be independently configured to control individual loads.

Expansion port : Up to two RK4 relay modules can be connected to the device with a ribbon cable, providing up to a total of 8 additional relay outputs
