- Monitor Engine or Motor Driven Pumps and Compressors
- 47 Normally Open (N.O.) or Normally Closed (N.C.) Sensor Inputs
- CSA* and Factory Mutual** Listed
- Rated for Hazardous Locations
Power: Supplied by CD ignition of an engine, 120 VAC line, or by 12 or 24 VDC battery.
Power Inputs (Operating Voltage):
LCDT-PS-CD (R)-P: 90-250 VDC, CD ignition, positive ground.
LCDT-PS-CD-N: 90-250 VDC CD ignition, negative ground.
LCDT-PS-120/24/12: 120 VAC (6 VA), 24 VDC (1 watt), 12 VDC (0.5 watts).
Sensor Inputs: Accepts up to 47 sensors (NC version only 45) via a ribbon cable. The LCDT system was designed to be used with sensor switches having normally open or normally closed contacts such as Murphy Swichgage instrument. NOTE: An approved isolation barrier such as a thermocouple type barrier, must be used between sensor switch and input terminals if sensor outputs come from any energy storing device such as a relay or transistor.
