Description

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-but­ton keypad on the face of the unit.

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).

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.

Applications

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:

■

Air compressors

■

Gas compressors■Water treatment

■

Fire pumps

■

Sewage pumps

■

Generators

■

Process control

■

Burner systems

Series 1400 System

The basic S1400 system consists of (1) the monitor, (2) a sensor input termi­nal strip assembly (rail mount) (3) a 36 inch (914 mm) flat ribbon cable for
connecting the terminal strip to the monitor, (4) a power supply which
includes the control Inputs/Outputs and an intrinsically safe barrier, with
cable assembly. S1400SP; same as the S1400 system except the (1) monitor,
includes an extra connector (port) for connection to S14BCM92 relay board
expansion or for a digital output to interface with micro-controllers.

NOTE: Each unit is programmed to the customer specifications.

Accessories

S14RSA92 Adapter: Used to interface the S1400 opto-isolator input (also

called run input) to CD ignition systems. (Not approved by CSA.)

S14BCM92 Relay Board Expansion: Can either be used to expand the

S1400 relay capabilities an additional 7 relay control outputs, or for binary
representation of the alarm/shutdown terminal number(s) to a PC board.
(Not approved by CSA.)

LCDT-ISB Intrinsically safe barrier for N.O. sensors

accept non-intrinsically safe normally open inputs and convert them to
intrinsically safe outputs. Each LCDT-ISB provides for two (2) channels.

Warranty

A two-year limited warranty on materials and workmanship is given with this
Murphy product. Details are available on request and are packed with each unit.

In order to consistently bring you the highest quality, full featured products, we reserve the right to change our specifications and designs at any time.
