Product Description
The Series S1501 system is a microprocessor based alarm, shutdown, and control system
with tachometer/hourmeter function. It tells in alphanumeric characters which protective device
has signaled an alarm or caused equipment shutdown. Application programming is completed
at Murphy and can be changed in the field.
The system consists of:

S1501 Head

Power Supply - explosion proof

Terminal Block Assembly, rail mount type, accommodates 32 sensors (2 needed for 64
sensor models)

Flat Ribbon Cable - 36 inch (914 mm) to connect the terminal block to the head.
The S1501 is powered from 120 VAC or 12/24 VDC. It is approved for Class I, Div. 1, Groups
C & D areas.
S1501 Head
The Head is the brain of the micro-controller system. It contains a microcomputer, an
alphanumeric display and keypad for operator access to field adjustable functions, and 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 S1501 data
registers.
Alphanumeric Display
The S1501 Head displays each mode of operation . The display is a dot matrix alphanumeric
32-character display arranged in two lines (each with 16 characters). By observing the monitor,
the operator can determine the operating status of the control system.
Power Supply
An explosion-proof enclosure designed for Class I, Division 1, Groups C & D hazardous
locations contains the supply voltage conditioning circuits, head power supply, and the
intrinsically safe barriers for isolation between the power supply and the low energy head
circuits. The power supply accepts 120 VAC, 50-60 Hz and/or 12-24 VDC input power.
12-24 VDC power can be used as primary power or as a backup source of power when
120 VAC is used.
