700-FSM4UU18 High Performance Multi-Function Timing Relay | Allen Bradley

Product Overview

The Allen Bradley 700-FSM4UU18 stands as a high-performance, multi-function timing relay designed for precision sequencing in complex control circuits. This versatile unit consolidates multiple timing modes into a single DIN-rail mounted device, providing critical delay and interval logic for motor starters, conveyor systems, and industrial automation panels. Despite the manufacturer’s discontinuation in early 2022, we offer this unit as 100% Brand New original factory stock, ensuring your legacy systems maintain peak operational integrity without the need for immediate hardware redesign.

Technical Specifications

Engineering Advantages

• Universal Voltage Compatibility: The 700-FSM4UU18 operates across a wide power spectrum from 24V to 240V AC/DC. This wide-range input eliminates the need to stock multiple variations for different control voltages, simplifying your spare parts inventory and preventing installation errors caused by mismatched voltage levels.

• Massive Timing Flexibility: The module covers an expansive timing envelope from 0.05 seconds up to 60 hours. Rotary switches on the front face allow for immediate, tool-free adjustments. This flexibility makes the relay ideal for both rapid-cycling applications and long-duration process delays.

• High-Density Control (DPDT): The unit features 2 changeover contacts (DPDT). This allows a single relay to switch two independent circuits simultaneously, reducing the total component count in your control cabinet and saving valuable DIN-rail space.

• Rugged Timing Precision: Engineered for high-performance industrial environments, the internal circuitry maintains high repeatability and accuracy even under fluctuating temperature conditions. It replaces standard timers that drift over time, ensuring your process sequences remain synchronized.

FAQs

• How do I select the specific timing function on the 700-FSM4UU18?

  The front panel features dedicated rotary dials. You select the primary function (such as On-Delay, Off-Delay, or One-Shot) and the time range using the top dials, then fine-tune the specific time setting using the percentage-based potentiometer on the bottom.

• Can I use this relay in a DC-powered control system?

  Yes. The "UU" designation in the part number indicates a universal voltage range that supports both AC and DC inputs. It functions perfectly on 24V DC battery systems as well as standard 120V or 230V AC plant power.

• Since the manufacturer discontinued this model in 2022, is this a used or refurbished unit?

  Absolutely not. This 700-FSM4UU18 is 100% Brand New and has never been installed or energized. It ships in its original factory packaging, providing the exact same reliability and service life as a unit manufactured prior to the discontinuation date.

• What should I consider during installation for electromagnetic compatibility?

  Ensure secure terminal connections to prevent arcing. While this relay features internal shielding against industrial noise, you should route high-power motor leads away from the timing relay control wiring to prevent induced interference in sensitive timing sequences.
