Hardwire Electronics PDM25 V2 The PDM25 V2 is the newest PDM (Power Distribution Module) from Hardwire Electronics, a natural update to the outgoing PDM25 V1. With new features such as High/Low side outputs, 9 Axis IMU, improved CAN bus and more. CANBus compatible with most Standalone ECUs such as FuelTech, MoTeC, Haltech, Holley, ECUmaster, Link, and more A PDM is a device used to replace conventional relays and fuses in a vehicle electrical system. The Hardwire Electronics PDM25 takes inputs from physical switches, analogue voltages, or the CAN bus, and provides power to different electronic devices such as radiator fans, fuel pumps and head lights. The current being drawn from each connected device is continuously monitored. If the measured current is too high due to a fault, the PDM switches off the respective output to prevent further damage to the wiring loom or the connected device. The PDM can then retry the output to see if the fault has cleared. Product Details Included PDM25 4x DT/AT Connectors + Contacts + Wedgelocks 1x M8 Ring Terminal 1x Ring Terminal Cover USB Flash Drive with Pro PDM Configurator Software and Instruction preloaded 2m USB Cable Printed A4 instruction manual 2x Hardwire Electronics Stickers Technical Specification General Size 200 x 160 x 54 mm Weight 690g Operating Temperature -55 – 90C [ -67 – 194 °F ] Construction Glass Fibre reinforced plastic IP Rating IP67 Water and Dust Ingress Protection Connectors 4x DT/AT Inputs Type 16 analogue inputs which can also serve as digital inputs. Measurement Range Each input can measure voltages between 0-28V, independent of the battery voltage. Measurement resolution 12-bit or 0.01V Frequency Measurement Automatic frequency measurement up to 300Hz Protection Fully protected for input voltages between -24V to 40V. Pull Up/Down Resistors Each input has a permanent 200K Pull-up and 40K Pull-down resistor Added Features Configure as active high or low. Configurable Hysteresis voltage. Latching or momentary operation. Outputs Type 4 high/low side outputs 80A peak, 20A continuous (Pin-limited to 13A @125degC), with reverse current protection. 21 high side outputs 80A peak, 20A continuous (Pin-limited to 13A @125degC) Combined 120A combined output maximum current Output current control steps 100mA Protection Each output is overcurrent, overtemperature, load dump and reverse polarity protected. Soft Start PWM soft start can be enabled on outputs to limit inrush current. PWM Each output can be Pulse Width Modulated based on a user defined variable. This can limit the speed of radiator fans, fuel pumps, and dim lights. 1000Hz maximum PWM frequency Added Features Outputs can be configured to stay on for a specified time after the input is removed, useful for thermo-fans. Outputs can be retried multiple times after an over-current event is detected. CAN Bus Interface 1x CAN2.0A/B ports Bus Speed 50, 100, 125, 250, 500, 1000 kbps Termination Resistor Both CAN bus ports have software selectable CAN termination resistors. Input Stream 100x inputs, fully customisable variable parsing with bit masking, math functions, and compound CAN message filtering Output Stream 100x Outputs, Fully customisable CAN frame construction with math functions CAN Keypad Support for Blink Marine, Grayhill, Motec, Haltech and Marlin CAN keypads.
