Theanalog input devices to which analog inputs are wired are typically current loop or voltage range devices like 4-20 mA transmitters or0-10V transmitters. Refer to Analog Input Module Specifications on page 10 for module details.Note: Ground the shield on one end only. It is recommended to limit the cable impedance by keeping the cable length as short aspossible. Limiting the distance from ground to the shield is also recommended. The recommended cable is a Belden TM 8761 orequivalent.Note: When an input channel in not used, jumper from V to C eliminating noise from causing erroneous readings for that channel.Figure 37: Analog Input Wiringa) Input Moduleb) Jumperc) Shield (Ground One End Only)d) Current Input Devicee) Voltage Input Devicef) Shield (Ground One End Only)Wire Type Wire Size Terminal TorqueSolid Cu-90°C #14 - # 22 AWG 4.5 in-lbsStranded Cu-90°C #16 - # 22 AWG 4.5 in-lbs12345678I0C0V1I1C1V2I2C2V3I3C39101112- +JIC-0012V0IV acde fb
