Description
(standard Series 1501)
The Series 1501 system can be configured to mon-
itor applications such as: Air and Gas
Compressors, Natural Gas Refueling, and other
Industrial Operations. For a list of applications and
our cataloged programs contact a Murphy sales
representative. Custom programming available at
additional charge.
The Series 1501 instrument is a microprocessor-
based alarm, shutdown and control system with
tachometer/hourmeter function. It annunciates
in alphanumeric characters the protective device
that has signaled an alarm or caused equipment
shutdown. Information is called up and adjust-
ments are made on a six-button keypad on the
face of the unit. Configurations such as: Alarm
or Shutdown Nomenclature, Preset Timers, and
Tachometer Calibration can be made in the
field.

Murphy’s Series 1501 system has seven SPDT
relays. On the standard model, the relays are
assigned to the following functions: Lube,
Crank, Ignition/Motor, Fuel Valve, Load,
Alarm, Shutdown.
The complete Series 1501 system consists of a
head (monitor), sensor input terminal strip (two
needed for 64 sensor models), 36 inch (914
mm) flat ribbon cable(s) for connecting the ter-
minal block to the head/monitor, and a Class I,
Div. 1, explosion-proof power supply.

Specifications
Interface Output: Factory configured for
RS232; field-selectable for RS485 (specify
for factory configured RS485).
Power Consumption: 120 VAC (7.5 VA);
12 VDC (3.5 watts); 24 VDC (3.5 watts).
Sensor Inputs: 32 to 64 N.O. and/or N.C. inputs
Alphanumeric Display: 2 lines, each line with

Power Supply Enclosure: Explosion-proof,
Class I, Division 1. Intrinsically safe barrier
built into the power supply, 120 VAC with 7
form “C” relay outputs for the following
functions (with standard S1501):
12 or 24 VDC. The head/monitor is rated intrin-
sically safe and includes a communication port:
RS232 or RS485 (Modbus RTU slave). This
port allows for remote control functions such as
Start/Stop, Load/Unload, etc., and for access to
Series 1501 registers.
Outputs: 7-SPDT relay outputs, 5 A, 1/16 HP,
125/250 VAC/ 1 A, 30 VDC.
NOTE: For hazardous areas an approved isola-
tion barrier must be used between sensor switch
and input terminals if the sensor output comes
from any energy storing device such as a relay or
transistor.
