MURPHY POWER IGNITION
MPI Control Systems utilize the latest microprocessor based designs to provide improved programming and diagnostics for today's industrial gas engines.
Operators of MPI controllers have more information to be used locally or remotely, giving them "full authority" to fine tune their operations for enhanced efficiency.
• 16-bit and 32-bit microprocessor controllers
• Five Timing Reference Options including Camless Operation
• Remote PLC engine management system or cellular communication
• Field-programmable from front panels
• Run-time diagnostics and prognostics
• Two field-adjustable timing schedules
• 4-line window display (local or remote)
• True Primary and Secondary Diagnostics
• Highly accurate and stable timing (±0.25°)
• Two analog inputs for remote timing control
BENEFITS• Increased spark life
• Equalizes cylinder output
• Less RPM variations
• Reduces unscheduled downtime
• User friendly: no chips to change or remove
• No PC or handheld programmer required
• Easier operation
Power Requirements:
MPI-16/8: 18-32 Volts (24 VDC nominal) 3.0 Amps max.
Note: The input current is dependent on firing rate.
MPI-32: 18-32 Volts, 6.0 Amps max.
Temperature: Operating Range : –20° , +70° C.
CSA Certified for Class I, Div 2, Groups B, C, D
MPI-16: Fires 16 outputs, no simultaneous pairing.
MPI-8: Fires 8 outputs, no simultaneous pairing.
MPI-32: Fires 32 outputs, 2 outputs can fire simultaneously.
Energy Storage:
MPI-16/8: 125 mJ max, per tank cap
MPI-32: 180 mJ max, per tank cap
Output Electrical Specifications:
MPI-8: Single tank capacitor
MPI-16: Dual, alternately fired tank capacitors
MPI-32: Quad, alternately fired pairs of tank capacitors
Ignition Outputs are High-side firing referenced to the “T” pin on the output harness. Note: These outputs are not ground referenced unless the “T” lead is grounded. Recommend careful adherence to installation instructions.
Maximum Output Current Pulse Rating: 40 Amps
Note: Current pulse amplitude is dependent on the coils in use and the tank cap voltage.
IT-230 Series coils: 7 Amp pulse @ 230Volts
IT-150 Series coils: 35 Amps @ 150 Volts
IT-250 series coils: 20 Amps @ 250 Volts
4/20 mA Inputs:
4/20mA A: This input retards timing (if programmed) when schedule A is active.
4/20mA B: This input retards the timing (if programmed) when schedule B is active.
Communications:
MPI-8/16: An auxilliary comm port is available, RS-485 interface, Modbus protocol
Note: This port has a user programmable slave ID, runs at 9600 baud. All parameters available and can be modified in parallel with main front panel display.
Note:
MPI Controllers have multiple inputs/outputs for all operating parameters. Please consult the Operating Manual for each MPI unit.
