Allen Bradley 1746-FIO4V SLC 500 Fast Analog Combination Module

Product Overview

The Allen Bradley 1746-FIO4V functions as a high-speed, fast-response analog combination input/output module within the legacy SLC 500 automation platform. This hardware consolidates multi-channel processing into a single slot by hosting two analog inputs and two analog voltage outputs simultaneously. It intercepts real-time field signals from pressure transmitters or flow meters and modulates proportional output control signals to drive high-speed servo valves, actuators, and variable frequency drives. We guarantee this unit arrives in 100% brand new, original factory-sealed condition.

Technical Specifications

Engineering Advantages

• Ultra-Fast Sub-Millisecond Task Execution: The module boasts an internal channel update time of 512 microseconds. Combined with a blazing-fast 2.5-millisecond output step response, this hardware solves a critical industrial pain point by eliminating propagation lag in time-sensitive, closed-loop pressure or tension control applications.

• Dual-Function High-Density Consolidation: By pairing 2 inputs and 2 outputs on a single circuit board, the card saves valuable space inside small chassis racks. This high-density layout allows engineers to deploy standalone machinery or compact hydraulic skids without requiring multiple dedicated analog input and output cards.

• High-Precision Signal Synthesis: The 14-bit output digital-to-analog converter generates exceptionally smooth, step-free voltage curves between –10V and +10V. This high resolution prevents actuator jitter and minimizes mechanical stress on sensitive proportional control valves on the factory floor.

• Robust Noise Attenuation: The 7 kilohertz input frequency bandwidth ensures crisp signal tracking while filtering out high-frequency electromagnetic interference (EMI) generated by surrounding motor cabling and heavy industrial switchgear.

FAQs

• Does this 1746-FIO4V module arrive with its original factory packaging?

  Yes. We supply this module as a 100% brand new, authentic factory item inside its original Rockwell Automation box. It retains all corporate anti-static packaging, factory inspection tags, and tracking bar codes unblemished.

• Can I wire a 4–20 mA current sensor directly to the input channels?

  Yes. The input channels support standard 0 to 20 mA signals natively, which comfortably accommodates 4–20 mA industrial instrumentation loops. You configure the selection between voltage or current input types via the internal circuit jumpers before sliding the module into the rack.

• Does the 1746-FIO4V output stage support a 4–20 mA current loop out?

  No. The 1746-FIO4V features voltage-only outputs, delivering a –10 to +10V DC signal. If your field actuators require a current loop (mA) control signal, you must select the alternative 1746-FIO4I module instead.

• What are the specific chassis slot limitations for installing this card?

  The module utilizes standard backplane dimensions and fits into any available I/O slot of a 1746 chassis, except for Slot 0 on the far left, which always hosts the primary SLC 5/0x processor. Ensure you verify your power supply capacity against the 55 mA (5V) and 150 mA (24V) backplane draws before installation.
