12 Solid State 24V DC Source Output Module

Publication 1762-IN011B-EN-P - June 2013

Sourcing Output - Source describes the current flow between the I/O module and the field

device. Sourcing output circuits supply (source) current to sinking field devices. Field devices

connected to the negative side (DC Common) of the field power supply are sinking field devices.

Field devices connected to the positive side (+V) of the field supply are sourcing field devices.

Typical Loading Resistor - To limit the effects of leakage current through solid-state outputs, a

loading resistor can be connected in parallel with your load. Use a 5.6k ohm, 1/4 W resistor for

transistor outputs, 24V DC operation.

Recommended Surge Suppression - Use a 1N4004 diode reverse-wired across the load for

transistor outputs switching 24V DC inductive loads. For additional information, refer to

Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley publication 1770-4.1.
