Description

The Allen-Bradley 1746-NO8I is an eight-channel analog output module designed specifically for the Allen-Bradley SLC 500 modular control system architecture. This module provides high-density current output capabilities for sophisticated industrial automation tasks requiring precise conversion of digital controller values into analog control signals. Each of the eight channels is independently configurable, allowing seamless integration with various current-driven actuators, valves, drives, and instrumentation loops within a single slot footprint.

Engineered for deployment in standard SLC 500 chassis environments (excluding slot 0), the 1746-NO8I interfaces directly with the system backplane to receive update data from the processor. It features robust channel-to-backplane optical and transformer isolation, protecting sensitive controller logic from ground loops and field-side electrical transients. Onboard status indicators provide continuous visual confirmation of individual channel activity and module health, minimizing troubleshooting downtime in continuous process and discrete manufacturing applications.

Features

  • Eight independently configurable current output channels supporting standard industrial control ranges
  • Compatible with any standard SLC 500 I/O chassis slot except slot 0 (Processor slot)
  • Selectable backplane or external 24VDC power sourcing via internal jumper J4 configuration
  • Integrated LED status indicators for real-time module health and individual channel monitoring
  • Robust 500VDC isolation barrier between field wiring and system backplane
  • Factory-calibrated analog circuitry ensuring long-term signal stability and precision across fluctuating ambient temperatures

Applications

  • Proportional valve and damper actuator positioning in process control loops
  • Speed and torque reference signal generation for variable frequency drives
  • Interfacing with analog chart recorders and external data acquisition systems
  • Closed-loop temperature, pressure, and flow regulation in chemical and water treatment facilities
  • Multi-axis coordinated motion control reference distribution

FAQ

Can the Allen-Bradley 1746-NO8I be placed in slot 0 of an SLC 500 chassis?

No. Slot 0 of an SLC 500 modular chassis is strictly reserved for the system processor or PLC controller. The 1746-NO8I module can be installed in any other available I/O slot within the chassis.

What output signal ranges are supported by the 1746-NO8I module?

The module supports independently configurable current ranges, specifically 4 to 20 mA and 0 to 20 mA across its eight available output channels.

How is power supplied to the 1746-NO8I analog output channels?

Power can be supplied via the system backplane (5VDC and 24VDC) or from an external 24VDC power source, depending on the configuration of the internal jumper J4.

Does the 1746-NO8I provide electrical isolation?

Yes, the module features 500VDC isolation between the field wiring and the system backplane to protect controller electronics from noise and ground loops.
