Mod-Tronic’s MT300 consists of a three-channel transformer temperature monitor and alarm system that controls three relay outputs based on user-programmable set points. The system offers users a completely programmable monitor and alarm with improved measurement range and universal inputs. The microprocessor-based design maintains accuracy over a wide range of temperatures and conducts regular self-checks to ensure correct operation. Additionally, one of the relay outputs is specifically designed for control of a cooling fan, and the user-configurable fan exercise option extends the fan life and reduces bearing lock-up. Applications include use in pumps, compressors and motors.
