M-TIO
Modulo I/O Modbus RTU
M-TIO modules provide a compact input/output solution for Modbus RTU master controllers. The unit has incredibly flexible input/output configuration that allows many applications to be controlled by a single device. A combination with any Modbus wall unit greatly simplifies installation on the wall-unit side, as the IO module can be located close to the terminal unit being controlled, with only communication wiring into the wall unit. The mains powered versions eliminate the need for additional power-supplies or transformers further reducing cost and installation labor M-TIO also hosts a battery backed-up real-time-clock.
Relay Outputs: 5 relay outputs are provided. Each relay can be used independently, and a specific set of three can be configured for 3-speed fan control.
Triac Outputs : 2 triac outputs are provided with flexible configuration options, allowing control of on/off thermoelectric (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: :4 0-10VDC analog outputs are provided for controlling modulating valve or damper actuators. Two of these can be configured to function as digital inputs.
Expansion port: up to two RK4 modules can be connected to the device with a ribbon cable, providing 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 day of the week.
