BIU Testing

The ACMT-5000 CMU Tester will run a series of comprehensive tests on the CMU used in the ATC Cabinet monitoring system to verify that it is functioning in compliance with the published standard. The tester is compatible with both the high voltage and low voltage CMU models (CMU-2212-HV and CMU-2212-LV). The CMU under test plugs into a slot in the front of the tester. No external cables or fixtures are required.

Where do you keep your big box of suspect BIUs; under your desk or tucked nicely out of sight on that dusty old shelf?  No longer do traffic signal techs have to play the "BIU Swap Game"!  Quickly and reliably check any BIU with the BIUT-820 which provides comprehensive, fully automated testing in the field or at the shop.
