2.15 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.
