Altronic DD-40NTV

The latest version of Altronic’s industry standard annunciator, the DD-40NTV series monitors up to 40 electrical contacts that represent limits on critical operating parameters such as engine or process pressures, temperatures, levels, etc. Upon detection of a fault from one of the monitored points, the annunciator displays the corresponding 2-digit fault code for that point and generates an output signal (typically to close a fuel valve and ground the ignition). The DD-40NTV annunciator offers integral tachometer and hourmeter functions as well as overspeed protection adjustable from the front keypad. The DD-40NTV series also provides a ModBus compatible, RS-232/RS-485 serial communications interface for connection to an RTU or PLC.
