Field Wiring
Field wiring to the module shall consist of separate shielded twisted pair wires. The acceptable field wire gauge shall be AWG 20 to AWG 12. In a 2-wire field configuration, the maximum field wire length is a function of the required accuracy. Wiring between the module and the intrinsically safe field device should follow intrinsically safe wiring practices to avoid the transfer of unsafe levels of energy to the hazardous area.
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.
RTD/Resistance Input Wiring
When the Universal Input module is configured as a RTD/Resistance Input module, the maximum wire length (distance to a sensor) for a 3 or 4-wire configuration is 200 meters.
Thermocouple/Millivolt Input Wiring
When the module is configured as a Thermocouple/Millivolt Input module, the sum of thermocouple source or voltage source impedance and wire resistance should not exceed 200 ohms for rated accuracy.
Fixed Wiring System
The Quantum140 AII 330 00 Intrinsically Safe Analog Input module is designed with a fixed wiring system where the field connections are made to a 40-pin, fixed position, blue terminal strip which is plugged into the module.
Terminal Strip Color and Keying Assignment
The module’s 140 XTS 332 00 field wiring terminal strip is color-coded blue to identify it as an intrinsically safe connector.
The terminal strip is keyed to prevent the insertion of an inappropriate connector in the module. The following table provides the keying assignment.
