Connecting Analog Outputs (OUTP302, OUTP303)
With the purchase of OUTP302 or OUTP303, the controls are equipped with analog
outputs. OUTP302 provides 2 connections for monitoring temperature and humidity or
CO2. OUTP303 provides 3 connections for monitoring temperature, humidity and CO2.
Analog outputs are either milliamps (4-20mA) or voltage (0-5V) signal output that
represents each of the displayed temperature, humidity or CO2 values. These options
can be used for connection to in-house data acquisition, recorder, or alarm system.
Parameter Analog Output Current Corresponding Value

Connect shielded wires to the appropriate signal terminals: I(+) for current (mA) or V(+)
for voltage (DC). For both current and voltage outputs, COM(-) is common terminal.
