CAUTION
UNWIRED INPUTS CAUSE INVALID READINGS
When configured for voltage inputs (no jumper installed between INPUT(+) and ISENSE terminals), if a broken field wire occurs, readings will be non-zero and not predictable. The field wiring terminal strip must not be removed when the module is operating.
Failure to follow these instructions can result in injury or equipment damage.
The following figure shows the wiring diagram for the 140 ACI 030 00 module.
External Wiring Recommendation
  1. The user supplies the current and voltage sources (installation and calibration of fuses are at the discretion of the user).
  2. Use shielded signal cable. In noisy environnements, twisted shielded cable is recommanded.
  3. Shielded cables should be connected to PLC’s ground.
  4. A Shield Bar (STB XSP 3000 and STB XSP 3010/3020) should be used to connect the shielded cable to ground.
  5. The maximum channel to channel working voltage cannot exceed 30 Vdc.
  6. N / C = Not connected.
NOTE: if polarity is reversed the analog values becomes zero nothing happens to channel. The module is polarity sensitive and will read in one direction and not in the other direction but stay on zero.
NOTE: When field wiring the I/O module, the maximum wire size that should be used is 1-14 AWG (1.5 mm²) or 2-16 AWG (2 mm²); the minimum size is 20 AWG.
NOTE: The tightening torque must be between 0.5 Nm and 0.8 Nm.
NOTICE
DESTRUCTION OF ADAPTER
  • Before tightening the locknut to the torque 0.50...0.80 Nm, be sure to properly position the right-angle F adapter connector.
  • During tightening, be sure to maintain the connector securely.
  • Do not tighten the right-angle F adapter beyond the specified torque.
Failure to follow these instructions can result in equipment damage.
