Wiring the Digital Output
DANGER
EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-hazardous.
Performing this operation in a hazardous area could result in an explosion.
The digital output connection is on the terminal plate under the rear cover. Route the DO wires
through the conduit fittings and connect them on the terminal plate. There is one connection for
the DO and another for ground.
Note
When using the digital output to drive an inductive load (such as a relay coil), place a suppression
diode across the load. This protects the DO from the reverse Electro-Motive Force (EMF) spike
generated when the inductive load is switched off.
