Five relay outputs are provided, each with 5A rating. Triac
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 the use of both triacs.
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.
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.
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.
