# Module Addressing The J1939 source address is configured with the `ADR0` and `ADR1` pins. | ADR0 | ADR1 | Address | | ------ | ------ | --------- | | N/C | N/C | 80 (0x50) | | Ground | N/C | 81 (0x51) | | N/C | Ground | 82 (0x52) | | Ground | Ground | 83 (0x53) | # Output Overcurrent Blanking Time To prevent transients from causing outputs to turn off due to overcurrent, a blanking time is added which allows outputs to briefly stay in overcurrent. If the output stays above the current limit for this duration, the output is turned off. ![[overcurrent-blanking.svg]] # Coil Economising Each output can be configured to apply an economising sequence. The delay period and duty cycle can be configured to suit the load. By setting the duty cycle to 0%, this feature can also be used to generate output pulses with predetermined durations. ![[coil-economising.svg]]
