The MTL RTK 725B combined annunciator & event recorder is the ideal solution for monitoring critical alarms whatever the size or complexity of the system. The 725B uses CANBUS communication technology and a multi-redundant design to offer a combination of reliability, flexibility, usability and cost of ownership. This also means that there is no single point of failure.

The 725B is supplied with comprehensive diagnostics to monitor all aspects of the system operation. Any fault that is detected will be indicated on the front LEDs and can also drive a diagnostic relay for external indication. It will monitor the field contact voltage and also provide an early warning of wiring problems and ground faults.

The 725B features modular construction. Units can be assembled in almost any shape and size from 1 to 256 channels with a choice of three window sizes and six colors. It is fully configurable for each individual point by connecting the unit to PC or laptop through a standard USB connection.
