*The PT3000 sensor is not recommended for floating control (real time - discharge or return configured as space sensor). The PT3000 sensor is intended for monitoring or differential (staged) control.

Outdoor Air Humidity:

Type: Voltage/Current.

Supported Sensors: C7600B1000 and C7600B1018 (2 to 10V), C7600C1008 (4 to 20mA).

Return Air Humidity:

Type: Voltage/Current.

Supported Sensors: C7600B1000 and C7600B1018 (2 to 10V), C7600C1008 (4 to 20mA).

Outdoor Air Enthalpy:

Type: Current.

Return Air Enthalpy:

Type: Current.

Supported Sensors: C7400A1004 (4 to 20mA).

Air Filter Differential Pressure:

Type: Voltage.

Supported Sensors: Third party 2 to 10V, 0 to 5 inw ( 0 to 1.25 kPa) differential pressure sensors.

Space CO2 Sensor:

Type: Voltage.

Supported Sensors: Third party 0 to 10V, 0 to 2000 ppm CO2 sensors.

Outdoor Air CO2 Sensor:

Type: Voltage.

Supported Sensors: Third party 0 to 10V, 0 to 2000 ppm CO2 sensors.

Outdoor Air CO Sensor:

Type: Current.

Supported Sensors: Third party 4 to 20mA, 0 to 300 ppm CO sensor.

Monitor Sensor for network use:

Type: Voltage.

Supported Sensors: Third party 2 to 10V, 2 to 10 volts displayed.

Digital Inputs:

Dry-contact inputs are sensed using a 9 milliamp at 4.8 volts detection circuit. It is very important that the device used contains high quality, noncorroding contacts with resistivity that does not degrade; that is, increase over time. Use noble metal (such as gold or silver) or pimpled or sealed contacts to assure consistent, long-term operation.

Triac Outputs:

Triac Outputs on the RIO:

—Power ratings: 20 Vac to 30 Vac at 25 mA MIN to 500 mA MAX current for any voltage.
