Wire the Finger-safe Terminal Block
When wiring the terminal block, keep the finger-safe cover in place.
1. Loosen the terminal screws to be wired.
2. Route the wire under the terminal pressure plate.
You can use the bare wire or a spade lug. The terminals will accept a
6.35 mm (0.25 in.) spade lug.
3. Tighten the terminal screw making sure the pressure plate secures the wire.
Recommended torque when tightening terminal screws is 0.68 Nm (6 in-lb).
Configure the 1769-OG16 Module
The following I/O memory mapping lets you configure the 1769-OG16 module.
Output Data File
For each module, slot x, word 0 in the output data file contains the state of the
module’s output points. The module implements inverted logic on the TTL outputs.
An Output Data File bit set to 1 results in a logic low output voltage on the
corresponding output point. An Output Data File bit cleared to 0 results in a logic
high output voltage on the corresponding output point.
TIP
The terminal screws are non-captive. Therefore, it is possible to use a ring lug
[max 1/4 in. o.d. with a 0.139 in. minimum i.d. (M3.5)] with the module.
TIP
If you need to remove the finger-safe cover, insert a screwdriver into one of the
square, wiring holes and gently pry the cover off. If you wire the terminal block
with the finger-safe cover removed, you will not be able to put it back on the
terminal block because the wires will be in the way.
