1769-OF8C AB CompactLogix 8-Channel 4-20mA Output Card

1769-OF8C AB CompactLogix 8-Channel 4-20mA Output CardProduct Overview The Allen Bradley 1769 OF8C delivers high density analog control for CompactLogix (1768 1769) and MicroLogix 1500 controller series. This module provides eight high resolution current output channels specifically engineered to drive modulating control valves, Variable Frequency Drives (VFDs), I P transducers, and valve positioners. By utilizing a 16 bit Digital to Analog Converter (DAC), the 1769 OF8C enables extreme precision in PID

significantly lowering the total hardware investment per axis

1 dedicated current-only) Voltage Output Ranges +/-10 VDC

This protection allows for reliable operation in corrosive atmospheres (Class G3 per ISA S71

Q: How does the module react if the local CompactLogix controller transitions to Program Mode or suffers a communication fault

matching input limits from 95-130 VAC or 190-260 VAC without needing external step-down transformers

Plant operators deploy this module to secure mission-critical control data paths through automated physical link failover mechanisms

You establish the unique network node address by setting the physical rotary switches located on the side of the card body before sliding the module into the chassis
