R/MIO Input/Output Module

R/MIO modules provide a compact input/output solution for Ontrol's R-ION series programmable touch-screen room controllers.

This combination greatly simplifes installation on the wall-unit side, as the IO module can be located close to the terminal unit being controlled, with only comms wiring into the wall unit.

The mains powered versions eliminate the need for additional power-supplies or transformers further reducing cost and installation labor.

R/MIO input/output modules are not independently communicating devices. They can only be used with the R-ION controllers.

Inputs / Outputs

Fan Speed Control : 3-relays are provided specifically for 3-speed fan control. These relays can not be used independently.

Triac Outputs : 4 triac outputs are provided with flexble configuration options, allowing control of on/off thermoeelectic (PWM) or floating actuators or relays.  The triacs can be independently configured to control different loads. However, due to internal connections, all loads must be supplied from the same AC voltage. Floating (three-position) configuation requires use of two triacs.

Modulating Outputs : Two 0-10VDC analog outputs are provided for controlling modulating valve or damper actuators.

Relay Output : A single relay output with 10 A rating is provided.

Digital Inputs : Voltage-free contacts can be connected to the two digital input terminals.

Aux. supply output to field devices : Some mains-powered versions provide 24 VAC output for fied devices such as valve and damper actuators.

Expansion port : One RK4 relay module can be connected to the device with a ribbon cable, providing 4 additional relay outputs
