MURPHY TTDJ Series Digital Fault Annunciator

The innovative new TTDJ Series now gives you a
unique configurable annunciator with a built-in power
supply and hourmeter. A new modular design for easy
retrofit to most existing systems features an alphanumeric Liquid Crystal Display window with 1/2 inch
(13 mm), easy-to-read characters. It displays any fault
from the sensor inputs, elapsed engine running time,
and engine speed (optional, TTDJ-DC-T and TTDJIGN-T models only). Also located on the faceplate are
membrane keys for easy operation and configuration.
Highly reliable and versatile, the TTDJ accepts 32 sensor inputs supplied from normally open and normally
closed sensors. Plus each of the first 16 inputs can be
easily configured for Shutdown or Alarm Before
Shutdown*, can be locked out by one of two Start-Run
timers or configured as a Class C lockout. The StartRun timers are adjustable from:
0 to 5 minutes (B1); 0 to 9 minutes 59 seconds (B2).
The TTDJ-DC and TTDJ-DC-T are capable of communicating with controllers, PLC’s, computers or SCADA
systems by an RS485 serial communications port. An
optional Tachometer with Overspeed sensing feature
is available for all TTDJ Series models.
Test mode is provided for testing sensor circuits without
shutting down the equipment, plus on-board Elapsed
Time Meter is standard with all models.
Models are available for 12 or 24 VDC systems or for
negative ground CD Ignition systems.
