Model DC72D Generator Controller Color: Dc70dr Overview The DC72D is a compact generator controller that integrates metering and control with an LCD and LED display for clear monitoring of operating status, faults, and metering data. Housed in durable ABS, it supports remote start functionality and flexible input and output options for automating diesel generator sets. Key benefits Simplifies generator management by combining control, metering, and fault display in one unit. Broad compatibility with DC and AC supplies for use on a wide range of generator installations. Multiple programmable relay outputs and dedicated start and fuel relays allow custom control logic for automatic transfer and engine management. RS485 communication for integration with external monitoring systems. Compact footprint and standard panel cutout for straightforward retrofit and installations.

Weight: 0.9 kg. I O details Fuel relay output: 16 A DC positive supply voltage. Start relay output: 16 A DC positive supply voltage. Programmable relay output 1: 5 A DC positive supply voltage. Programmable relay output 2: 5 A noncontact relay with normally open and normally closed outputs. Programmable relay output 3: 5 A noncontact normally open output. Programmable relay output 4: 5 A noncontact normally open output. Programmable relay output 5: 5 A noncontact relay with normally open and normally closed outputs. Excitation output: max 1 A DC positive supply voltage. Switch value input: available when connected to a battery. Note: ensure semaphore control cable is connected to the display as required by the installation. Practical applications Automatic standby power for commercial buildings: manage generator start, fuel, and transfer controls while reporting runtime and fault conditions to a building management system via RS485. Industrial equipment backup: integrate into machinery panels to automate start and stop sequences and provide clear fault indication for maintenance. Remote generator sets on sites such as farms, telecom sites, or construction projects: use programmable outputs to tailor control logic for sitespecific requirements and monitor status remotely. Installation notes Cut a panel opening of 186 mm by 142 mm for mounting. Add a waterproof rubber gasket between the controller and the panel to achieve IP54 protection. Verify DC supply voltage within 8 to 36 V and AC input wiring conforms to 30 to 276 VAC phN range. Connect the semaphore control cable and RS485 as required by the control scheme. This controller provides a balanced combination of monitoring, programmability, and compact design for reliable generator automation and integration.
