Description
Feature
■
32 sensor is (N.Ond/or N.C.) for
alarm or shutdown
125/250 VAC/3A, 30 VDC.
The Series 1400 is a microprocessor based fault
annunciator. It tells in alphanumeric characters
which protective device has signaled an alarm or
caused equipment shutdown. Basic programming
for each application is completed at Murphy and
can be changed in the field by simply plugging in
a new preprogrammed microchip. Information is
called up and adjustments are made on a six-but-
ton keypad on the face of the unit.
NOTE: An isolation barrier (such as the Murphy
CDT-ISB) must be used between the sensor
itcnd input terminals if the sensor output
omrom aenergy storing device such as a
relr trator.

Four SPDT relays are available for alarm and/or
shutdown functions. A digital output version
(S1400-SP) port interfaces with micro-controllers
(7 bit straight binary code).

Run Sensing: Either ignition or switch input.
The S1400 and S1400-SP are powered from a
120 VAC or 12/24 VDC Class I, Division 1
explosion-proof power supply. The monitor is
rated intrinsically safe.
Operating Temperatures: 32 to 122°F (0 to 50°C).

Murphy provides various standard preprogrammed
configurations. If a customer sensor input configu-
ration is needed, Murphy will custom program
your unit at the time you order. Call for quote.
Case: ABS plastic, 1/4 DIN (90 x 90 mm).
Applications
†
Interface Output: Digital, 7 bit straight binary code.
Although designed primarily as an intrinsically
safe annunciator for gas compressors, the Series
1400 can be programmed to monitor most engine
or motor driven process applications, such as:
Display: Alphanumeric dot matrix, 2 line
32-character display.
Power Supply
Specifications
Power Consumption: 120 VAC (8 watts),
24 VDC (7.2 watts) or 12 VDC (2.5 watts).
Enclosure: Explosion-proof, Class I, Division 1.
Barrier: Intrinsically safe barrier built into
power supply, 120 VAC and 12 or 24 VDC
