Modules
3-7
8.
Configure the I/O point.
3.2.3 Removing an I/O Module
To remove an I/O module:
1.
Remove the wire channel cover.
2.
Unscrew the two captive screws holding the module in place.
3.
Gently pull the module’s lip out and remove the module from the
slot. You may need to gently wiggle the module.
4.
Install a new module or install the module cover.
5.
Screw the two captive screws to hold the module or cover in place.
6.
Replace the wire channel cover.
3.2.4 Wiring I/O Modules
All modules have removable terminal blocks for convenient wiring and
servicing. The terminal blocks accommodate wire sizes between 12 and
22 AWG.
Caution
Failure to exercise proper electrostatic discharge precautions (such as
wearing a grounded wrist strap) may reset the processor or damage
electronic components, resulting in interrupted operations.
To connect the wire to the removable block compression terminals:
1.
Bare the end (¼ inch or 6.3mm maximum) of the wire.
2.
Insert the bared end into the clamp beneath the termination screw.
3.
Tighten the screw.
Expose a minimum of bare wire to prevent short circuits. Allow some
slack when making connections to prevent strain.
Note
:
All modules have removable terminal blocks for convenient
wiring and servicing. Twisted-pair cable is recommended for I/O
signal wiring. The removable terminal blocks accept wire sizes
between 12 and 22 AWG.
3.2.5 Analog Input (AI) Modules
The Analog Input (AI) modules (AI-12 and AI-16) have four scalable
channels, which typically measure either:
4 to 20 mA analog signal, with the use of a precision resistor
(supplied).
1 to 5 Volts dc signal.
