TM-2

Device to monitor overheating

8-point temperature alarm. TM-2 acquires up to 8 NTC temperature sensors (range -10°C to 100°C) and signals the alarm visually via the respective LED and cumulative via relay with changeover contacts. TM-2 equips a test button to check operation; if pressed it activates the alarm relay and the lamp test function on the LEDs.

The alarm set points are individually programmable, in serial, from P.C through the TM-2 Utility program. Via serial interface with Modbus RTU protocol on RS-232 (or with RS-485 adapter), from P.C. o PLC., it is possible both to program the device and acquire the individual values of the detected temperatures and the status of the individual alarms

The typical application is monitoring, with the signaling of overheating, of electrical equipment inside the electrical panel in order to prevent the undesired intervention caused by the is thermal derating.
