Attached is a wiring diagram that shows you how to monitor the on/off state of a 24VAC circuit using the RX3000 station. In addition to the RX3000 and the RXMOD-A1 Four-Channel Analog Input module, you will need to obtain the following:

(1) IK Ohm Resistor

(1) 10K Ohm Resistor

(1) 24VAC-powered relay with one N/O contact available
