Description

The Allen-Bradley 1746SC-INO4VI is a high-performance, 4-point isolated analog output module designed for the SLC 500 programmable logic controller system. This module provides precise control for industrial applications requiring isolated voltage or current signals, ensuring signal integrity and protection against ground loops in complex control environments. It features 16-bit resolution to deliver accurate signal conversion and control for actuators, variable frequency drives, and other analog-controlled field devices.

Features

4-point isolated analog output channels.
Supports multiple current ranges: 0-20 mA, 0-21 mA, and 4-20 mA.
Supports voltage output ranges including 0-5V.
High-precision 16-bit resolution for superior control accuracy.
Fast step response time of 1 ms to 95% of full scale.
Non-linearity rating of 0.02% of full scale.
Robust design for integration into standard SLC 500 chassis environments.

Applications

This module is typically utilized in process control systems where galvanic isolation is required to prevent electrical interference between the controller and field instrumentation. Common applications include controlling process valves, dampers, motor speed controllers, and instrumentation displays in manufacturing, water treatment, and energy sectors.

Installation Guidelines

Ensure the SLC 500 chassis power is disconnected before inserting or removing the module.
Verify that the module is firmly seated in the chassis slot and secured with the provided mounting screws to ensure proper backplane communication.
Use shielded twisted-pair cabling for all analog I/O connections to minimize electromagnetic interference (EMI).
Ensure proper grounding of the cable shields at the control cabinet end only to prevent ground loops.
Keep signal wiring separated from high-voltage power lines and AC motor drive cables.
Maintain adequate ventilation within the enclosure to accommodate the 5W maximum thermal dissipation.

FAQ

Is the 1746SC-INO4VI compatible with all SLC 500 chassis?

Yes, this module is designed to fit into standard SLC 500 I/O chassis. Please ensure your power supply has sufficient capacity to handle the module's power requirements.

Does this module require external power for the outputs?

The 1746SC-INO4VI is an isolated module; please refer to the specific wiring diagram in the user manual for your installation to confirm if external loop power is required for your specific current or voltage output configuration.
