R/TIO and M/TIO Input Output Modules

General :

R/TIO modules provide a compact input/output solution for Ontrol's R-ION series programmable touch-screen controllers. With the R/TIO module, the installation on the wall-unit side is greatly simplified, as the IO module can be located close to the terminal unit being controlled, with only comms wiring into the R-ION wall unit. The mains powered versions eliminate the need for additional power-supplies or transformers further reducing cost and installation labor.

R/TIO input/output modules are not independently communicating devices. They can only be used with the R-ION controllers. On the other hand, M/TIO modules are general purpose input/output modules with industry-standard, open-protocol modbus RTU communications.

Both modules have the same I/O configuration, the only difference is the communications protocol.

These modules also host a battery backed-up real-time-clock.Therefore, time schedules can be implemented directly on the device, fully configurable locally from the connected R-ION or remotely from a supervisory system.

Universal Inputs :

8 inputs are provided, which can be configured as follows:

Input Pt1000 NTC 0-10 V Contact
In1 - Yes - Yes
In2 - Yes - Yes
In3 - Yes - Yes
In4 - Yes - Yes
In5 Yes - - Yes
In6 Yes - Yes Yes
In7 Yes - Yes Yes
In8 Yes - Yes Yes

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

Triac Outputs : 2 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) configuration requires use of both triacs.

Modulating Outputs : Four 0-10VDC analog outputs are provided for controlling modulating valve or damper actuators. Two of these points can be configured to function as digital inputs.

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

Real-Time-Clock : 4 time-schedules can each be independently associated with a relay output through configuration parameters. Each schedule allows 28 sets of start/stop times per week.
