Multiple Automatic Relay Tester
This highly modular system includes the RM software, a data router/power unit and (up to 16) test nodes. This configuration permits testing of multiple (up to 128) relays in one 15 to 20 minute block of time. Special connectivity components and techniques allow rapid, flexible and safe connection to the relays under test.

These features and the other features of the RM software comprise the most time efficient, accurate, and reliable field relay test system available today. For any operation with either many smaller control points or one (or more) large interlocking control points, the Multiple Automatic Relay Tester provides a terrific ROI and a convenient and effective, completely data-based, record keeping system.

Cab Signal Master

Cab Signal Master is a icroprocessor-based system specially developed to test all cab signal equipment in railroad locomotives and transit cars. Programmable default settings and straightforward operation allow simple "plug it in, turn it on" operation with very little instruction. The large easy-to-read display and weather-proof controls provide a rugged user interface. The portable tester accurately simulates both cab signal code rates and speed signals simul-taneously and can measure loop current while coding. For the most experienced technicians, the test system can be configured to automate tests.

Contact Resistance Measurement System (CRMS)

The CRMS is a system designed to allow any user to measure the resistance
of each set of relay contacts associated with the relay under test.
The test system consists of a CONTACT RESISTANCE MEASUREMENT
UNIT (CRMU), a MULTIPLE RELAY TEST RACK, as well as an
interconnect CABLE ASSEMBLY. Either DC or AC energy to pick and
drop relay coils under test for all contact measurements is supplied from
the CRMU and easily interfaces with the Multiple Relay Test Rack.
