CONNECTING THE RLY/TRG IN

The RLY/TRG IN connector is a two-pin terminal block connec- tor. When using this input for a switch-closure (or opening) event, the two terminals should be connected to the switch contacts directly. This type of event detection can be used with relay contacts as well.

If used with a logic-type device, the low-end of the logic connection should be connected to the minus (–) terminal and the active-end should be connected to the plus (+) terminal. This input is compatible with TTL & CMOS logic family de- vices. For the defined limits of input to this connector , please refer to the specification section.

TIP- This input can be used to switch between stand-alone preset operating modes without the need of a computer. Setup for this feature is avail- able through RS-232 or Telnet communications.

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 nor- mally-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 5-pin terminal block con- nector. 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.

ATTENTION! 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! If there is a need to switch

higher voltage or current levels with the CM16a, contact Technical Services for suggested solutions.
