DC engine and equipment control module designed for DC power systems from 8V to 36V Key benefits Broad voltage compatibility supports a wide range of vehicles and equipment powered by DC 8V to 36V, reducing the need for multiple control units. Low standby and run power consumption conserves battery power: at 24V standby up to 1W, running up to 5W. Accurate engine speed input and long runtime logging enable reliable monitoring and diagnostics with an engine speed signal range of 200 to 10000 Hz and maximum cumulative running time recording up to 99999.9 hours (minimum storage interval 6 minutes). Flexible outputs and configurable relays provide applicationspecific control without additional hardware. current outputs for direct actuator or motor control simplify wiring and installation. Switch input accepts a negativepole connection to the battery to improve conversion rates and ensure reliable signal detection in common DC setups. Main functions and specifications Operating voltage: DC 8V to 36V continuous supply. Power consumption (measured at 24V): standby maximum 1W; operation maximum 5W. Engine speed signal input: accepts 200 to 10000 Hz. Runtime logging: cumulative running time up to 99999.9 hours; minimum storage interval 6 minutes. Fuel output: 16 Amp DC positive supply voltage output. Motor output: 16 Amp DC positive supply voltage output. Excitation output: maximum 1 Amp DC positive supply voltage output. Configurable relays: Relay 1: 5 Amp DC positive supply voltage output. Relay 2: 5 Amp passive contact with one normally open and one normally closed output. Relay 3: 5 Amp passive contact normally open output. Relay 4: 5 Amp passive contact normally open output. Relay 5: 5 Amp passive contact with one normally open and one normally closed output. Switch input: effective when connected to the negative pole of the battery to improve conversion rates. Compatibility and performance Designed for integration with DCpowered engines, motors, and equipment that provide an engine speed signal within 200 to 10000 Hz. Outputs rated for current control (16 Amp) for fuel and motor drivers allow direct interfacing with many actuators and motor controllers. Multiple configurable relays provide both powered outputs and passive contact options to match a variety of control architectures. Typical applications Generator sets: control fuel and motor circuits, monitor engine speed, and log cumulative run time for maintenance scheduling. Agricultural and construction machinery: manage engine and motor outputs and switch auxiliary systems using configurable relay logic. Mobile equipment and fleet vehicles: integrate with vehicle electrical systems operating from 8V to 36V, capture engine speed signals, and provide robust outputs for actuators and starters. Installation notes Ensure the system supply is within the DC 8V to 36V range for continuous operation. Provide engine speed signal in the specified 200 to 10000 Hz range for correct RPM detection. Connect the switch input to the negative pole of the battery where required for improved conversion rates and reliable switching. Use the appropriate relay type or powered output based on whether a powered positive supply or passive contact is required by the controlled circuit. This control module offers versatile I/O, low power draw, and precise engine monitoring for a wide range of DCpowered equipment and vehicles.
