Field Wiring Field wiring to the module should consist of separate shielded, twisted pair wires.
The acceptable field wire gauge should be AWG 30 to AWG 18. 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.
Fixed Wiring
System
The Quantum140AIO33000 Intrinsically Safe Analog Output 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 140XTS33200 field wiring terminal strip is color-coded blue to identify
it as an intrinsically safe connector.
The terminal strip is keyed to prevent the wrong connector from being applied to the
module. The keying assignment is given below.
