The MMU-16E series Malfunction Management Units (MMU) exceed all the requirements set forth in the NEMA Standard TS2-2016 , Part 4. These units are intended to provide basic conflict and voltage monitoring for NEMA TS-2 traffic controller assemblies while maintaining downward compatibility with NEMA TS-1 assemblies.

The model MMU-16E includes a RYG Full Intersection display along with an RS232 port which is used to communicate with a Personal Computer using EDI ECcom software. Monitor status, event logs, and Signal Sequence History logs are stored in nonvolatile memory for diagnostic and archival purposes.
