Description

The Series 1500 is a microprocessor based alarm
and/or shutdown system. It tells in alphanumeric
characters which protective device has signaled an
alarm or caused equipment shutdown. Basic config­uration for each application is programmed at
Murphy and can be configured in the field.
Information is called up and adjustments are made
on a six-button keypad on the face of the unit.

The S1500 system consists of a monitor, a sensor
input terminal strip (rail mount type), a 36 inch
(914 mm) flat ribbon cable for connecting the ter­minal strip to the monitor, and a power supply
which includes the control Inputs/Outputs and
intrinsically safe barrier with cable assembly.

Four SPDT relays are available for alarm and/or
shutdown functions. A built-in RS232 communica­tion port allows interfacing with IBM
patible computer systems and micro-controllers.

The S1500 is powered from a 120 VAC or 12 or
24 VDC, Class I, Division 1 explosion-proof power
supply. The monitor is rated intrinsically safe.

Intrinsically Safe Barrier

Murphy’s LCDT-ISB intrinsically safe barrier for
hazardous applications, is designed for use with
two Normally Open sensors. This external barrier
accepts non-intrinsically safe, normally open inputs
and converts them to intrinsically safe outputs.

Applications

The Series 1500 can be configured to monitor
applications such as:■Generators

■

Air compressors

■

Gas compressors■Water treatment

■

Fire pumps

■

Sewage pumps

Features

■

32 sensor inputs (N.O. and/or N.C.) for alarm
or shutdown.

■

Six-button keypad for easy operation and
adjustments.

■

RS232 output for interface with computers and
micro-controllers (modem required).

■

Engine Automatic.

■

Series 1500 System

Power Consumption: 120 VAC (8 watts), 12 or 24 VDC (2.5 or 7.2 watts).

®

Sensor Inputs: 32 N.O. and/or N.C., such as Murphy SWICHGAGE

instru­ments. Inputs are factory-programmed as a Class A, B, C or P for shutdown,
alarm, or control function (specify).

Opto-Isolated Input: 12-120 VDC or 24-120 VAC, the opto-isolated input is

typically used as a run input, magnetic pickup and ignition.

Outputs: 4-SPDT relays, 4 A, 1/20 HP, 125/250 VAC/3A, 30 VDC.

NOTE: An approved isolation barrier must be used between the sensor
switch and input terminals if the sensor output comes from any energy stor­ing device such as a relay or transistor. (See LCDT-ISB

Barrier, at right).
