XTM Test Plugs and Card Extenders

Applications
The XTM test plug is available for testing modular type relays. The connection plugs can be removed from the modular relay, and the XTM test plug can be inserted for current injection testing and input/output access. The modular relays have two connection plugs and require two test plugs, one right-hand test plug and one left-hand test plug. The handle of the test plug may be pulled out and turned to the right for easy access to connection points.

The card extender provides versatility for testing plug-in modules in relay. The module to be tested can be removed from the relay, the card extender inserted in place of the module, then the module can be instered into the card extender. This gives complete access to module card for test purposes.
