Product overview This controller module accepts a wide range of DC and AC supply voltages and provides multiple outputs and configurable relays for engine and equipment control. It is designed for reliable operation, low power consumption, and flexible integration into generator, engine control, and power management systems. Key benefits Wide input compatibility: Accepts DC continuous supply from 8 V to 36 V and AC inputs across single phase, twophase, and threephase systems at 30 VAC to 276 VAC (phase to neutral), reducing installation complexity in mixed environments. Low power usage: Very low standby and operating power draw limits battery drain and keeps auxiliary power needs minimal. Standby at 24 V is maximum 1 W; operation at 24 V is maximum 5 W. Flexible control outputs: current fuel and motor outputs rated at 16 A DC positive allow direct drive of key actuators. Multiple configurable relays provide tailored control logic and alarm functions. Broad engine compatibility: Accepts engine speed signals from 200 Hz to 10 000 Hz, supporting a wide range of engine and alternator sensors. Long runtime tracking: Maximum cumulative running time records up to 99 999.9 hours with a minimum storage interval of 6 minutes, useful for maintenance scheduling and service records. Efficient excitation and switching: Provides an excitation output up to 1 A DC positive, and a switch input optimized for connection to the battery negative to improve conversion efficiency. Key functions and specifications Operating voltage: DC 8 V to 36 V continuous supply AC voltage input: Singlephase twowire 30 VAC to 276 VAC (phase to neutral); Twophase threewire 30 VAC to 276 VAC (phase to neutral); Threephase fourwire 30 VAC to 276 VAC (phase to neutral) Machine power consumption: Standby at 24 V maximum 1 W; Operation at 24 V maximum 5 W Engine speed signal: 200 to 10 000 Hz Maximum cumulative running time: 99 999.9 hours (minimum storage time 6 minutes) Fuel output: 16 Amp DC positive supply voltage output Motor output: 16 Amp DC positive supply voltage output Configurable relays: Relay 1: 5 Amp DC positive supply voltage output Relay 2: 5 Amp passive contact with both normally open and normally closed outputs Relay 3: 5 Amp passive contact normally open output Relay 4: 5 Amp passive contact normally open output Excitation output: Maximum 1 Amp DC positive supply voltage output Switch input: Effective when connected to the battery negative pole to improve conversion rates Performance and compatibility notes Designed to work with DC battery systems in the 8 V to 36 V range, making it suitable for common automotive, industrial, and standby power architectures. AC input tolerance from 30 VAC to 276 VAC phase to neutral supports use with a wide range of mains and generator outputs in single phase and multiphase installations. Engine speed input range accommodates typical ignition and alternator pickup frequencies, enabling compatibility with many engine types and existing tachometer sensors. Relay outputs include both powered and passive contacts so the module can drive loads directly or interface with external contactors and alarms. Practical applications Diesel or gas generator control: Use the fuel and motor outputs and configurable relays to control engine start, stop, and safety interlocks while monitoring cumulative run time for service intervals. Industrial enginedriven equipment: Integrate into pump, compressor, or mobile equipment control panels where wide AC and DC input compatibility and flexible relay logic are required. Backup power and standby systems: Monitor engine speed and run time, trigger alarms and transfer logic through the configurable relays, and use low standby power consumption to minimize battery drain. What this product solves Eliminates the need for multiple different controllers by supporting broad DC and AC input ranges and multiple phase configurations. Reduces wiring and external relay complexity by offering both powered outputs and multiple configurable relay contacts. Simplifies maintenance planning with a long cumulative runtime meter and consistent power consumption figures to manage battery and auxiliary power requirements. Technical reminders Ensure the switch input is connected to the battery negative pole for effective operation and improved conversion performance. Observe current limits on the 16 Amp fuel and motor outputs and the 5 Amp relay ratings when designing load circuits. Use the engine speed input within the 200 to 10 000 Hz range for reliable sensing and control logic. This module provides a reliable, technically flexible solution for engine and power control tasks where wide voltage compatibility, configurable outputs, and low power consumption are required.
