10 Wiring and Installation
10.2.9. AP2 Wiring
The AP2 expansion module can be wired to voltage or current feedback transducers.
Use shielded twisted pairs for all connections to inputs and outputs. Route the transducer
wiring separate from other wiring. You must provide the power supplies needed by your
transducers. See Wiring Guidelines for general wiring information.
Wire clamp screws must be tightened to max 7 b-in (0.8Nm).
NOTE:
The example schematics do not include transducer pin numbers, color codes, or power supply
requirements, since these vary between different transducers. To determine your power
supply needs and connector pin-outs or cable color codes, consult your transducer
manufacturers documentation.
Wiring Diagrams and Instructions
Voltage Feedback Transducers
Voltage feedback transducers can be connected directly to the Input + and Input -
connections of the desired axis. The Anlg Cmn and Case pins may be shared by the
axes. The following configuration is recommended:
Current Feedback Transducers
Current feedback transducers are connected in the same way as voltage transducers
except that a jumper must be inserted between the Input+ and Jumper for 4-20 mA
pins. The label indicates where this jumper should be connected. This places a resistor
internal to the RMC across the two inputs, thus converting the current to a voltage input.
The following wiring diagram shows a suggested configuration:
