CONNECTING THE RLY OUT

The RLY OUT connector provides access to the internal relay’s contacts for remotely controlling an external low voltage device or circuit. This internal relay is rated for 70V (DC or ACrms), 250 mA (switched) and is isolated from ground. There is one common terminal, one normally-closed contact terminal and one normally- open contact terminal. These are labeled as C, NC and NO on the rear panel. When the relay is not energized, the C terminal is connected to the NC terminal and the NO terminal is not connected; when the relay is energized the C to NC connection is opened and the C to NO connection is closed.

.

CONNECTING THE MONITOR CHAIN IN/

OUT

The MONITOR CHAIN connector is a five pin version of the “Phoenix”-type connector. The center pin is the shield connection for both the input and output of the monitor chain. Note also that the positive terminal of the input and output connections are on the outer pins of this connector.

DO NOT CONNECT VOLTAGES EXCEEDING 70 VOLTS (DC or AC rms) TO THE RLY OUT CONNECTOR! DAMAGE TO THE CM16a COULD RESULT OR CREATE HAZARDOUS OPERATING CONDITIONS!
