Series 1501 Selectronic® Micro-Controller/Annunciator S15-96122B Revised 07-06 Catalog Section 50 ■ Alarm/Shutdown for 32 or 64 N.O. or N.C. Sensors ■ Operating Sequence Selection ■ Field Adjustable Sensor Nomenclature ■ Selectable Sensor Lockouts Class A, B, C or P ■ Built-In Tachometer/Overspeed Function ■ RS232 or RS485 Modbus RTU Communications ■ Two Start/Run Timers and Elapsed Time Meter ■ CSA Certified or NRTL Approved for Use in Class I, Div. 1 Grps. C & D Hazardous Locations NRTL/C Description Applications The Series 1501 instrument is a microprocessorbased 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 adjustments 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 terminal block to the head/monitor, and a Class I, Div. 1, explosion-proof power supply. The Series 1501 system is powered from 120 VAC or 12 or 24 VDC. The head/monitor is rated intrinsically 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. The Series 1501 system can be configured to monitor 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. Features 32 or 64 sensor inputs (N.O. or N.C.) for alarm or shutdown. ■ Easy operation/adjustments Six-button keypad. ■ RS232 or RS485 Modbus RTU communications. ■ Automatic Engine Control. ■ Two Start-Run Timers. ■ Seven Control Relay Outputs. ■ Pre/Postlube Time Delay. ■ Automatic Compressor Loading. ■ Specifications 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 such as Murphy Swichgage® instruments. Field selectable as a Class A, B1, B2 , C , P or ESD for shutdown, alarm, or control function. Outputs: 7-SPDT relay outputs, 5 A, 1/16 HP, 125/250 VAC/ 1 A, 30 VDC. NOTE: For hazardous areas an approved isolation 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.
