Description

The Allen-Bradley 1746-OB6EI is a specialized high-current discrete output module designed for the SLC 500 programmable logic controller platform. This module provides six (6) sourcing DC outputs, each capable of handling up to 2.0 Amps of continuous current. Engineered for demanding industrial environments, the module features electronic protection and individual channel isolation, allowing for the use of independent power sources across different output points.

Features

High Current Capacity: Supports up to 2.0 Amps per point, with a total module capacity of 12.0 Amps.
Electronic Protection: Integrated thermal cut-out and current-limiting circuitry protect against short circuits and overcurrent conditions.
Individually Isolated: Each of the six outputs is isolated, providing flexibility in power supply configuration.
Auto-Reset Function: Channels automatically resume operation after cooling below the thermal threshold following a fault.
Status Indicators: Front-panel LEDs provide clear visual feedback on output status.

Applications

This module is ideal for controlling high-current DC loads such as solenoids, contactors, and actuators directly from the SLC 500 backplane. Its individual isolation makes it suitable for applications requiring mixed-voltage control or complex power distribution schemes.

Installation Guidelines

Power Down: Always disconnect backplane power before inserting or removing the module from the chassis.
ESD Precautions: Use a grounded wrist strap when handling the module to prevent electrostatic discharge damage to internal components.
Wiring: Ensure all field wiring is properly secured. Note that this module does not provide reverse polarity protection; verify DC polarity before connecting power.
External Protection: The internal electronic protection does not replace the requirement for external, code-compliant fuses or circuit breakers.
Environment: Ensure adequate ventilation within the enclosure to maintain operating temperatures within specified limits.

FAQ

Does this module include fuses?

No, the 1746-OB6EI features internal electronic protection (current limiting and thermal cut-out). This does not replace the need for external, code-compliant fuses or circuit breakers in your control circuit.

Can I use different power supplies for each output?

Yes, because the outputs are individually isolated, you can connect different DC power sources to each channel, provided they fall within the 10-30V DC operating range.
