ALSTOM UT150-1

Description

Product Description

The ALSTOM UT150-1 is a specialized timing relay or multi-function time-delay module from Alstom’s range of industrial control components. Designed for precision timing operations within automation panels and motor control circuits, this model provides reliable and adjustable control of time-based sequences. The primary function of the ALSTOM UT150-1 is to introduce precise delays in the operation of contactors, solenoids, and other loads, enabling processes such as star-delta motor starting, pump sequencing, or conveyor interlocking. Integrating the UT150-1 into a control system adds a layer of temporal logic that is crucial for safe and efficient machine operation. For engineers building or maintaining systems with Alstom components, the genuine ALSTOM UT150-1 offers a validated and compatible solution for implementing delay functions.

Product Parameters

• Manufacturer / Brand: Alstom

• Product Type: Timer Relay / Time-Delay Relay

• Model: UT150-1

• Series: Part of the UT series of timer relays.

• Timing Function: Offers a specific timing mode such as On-Delay (TON), Off-Delay (TOF), Interval, or Flasher, as denoted by the suffix “-1”.

• Time Range: Features an adjustable time delay, typically covering a wide range from fractions of a second (0.05s) up to several hours (e.g., 0.05s – 300h), adjustable via a potentiometer or selector switches.

• Supply Voltage: Operates on standard control circuit voltages (e.g., 24-240V AC/DC), powering the internal logic and output relay.

• Output Configuration: Contains at least one changeover (Form C) relay contact rated for switching control circuit loads (e.g., 5-10A at 250V AC).

• Mounting: Designed for DIN-rail mounting (35mm) for easy installation in control enclosures.

• Time Setting Method: May feature a rotary knob with a calibrated dial, DIP switches, or a potentiometer for setting the delay period.

• Status Indication: Includes LED indicators for power and relay status.

Advantages and Features

• High Timing Accuracy: Provides consistent and repeatable time delays, which is critical for coordinating sequential industrial processes.

• Versatile Functionality: The available timing functions (On-delay, Off-delay, etc.) make the ALSTOM UT150-1 suitable for a wide variety of control applications.

• Robust and Durable: Built to withstand the electrical noise, vibration, and temperature variations typical in industrial environments.

• Easy Installation and Setting: The DIN-rail format and clear time-setting interface allow for quick commissioning and adjustment.

• Clear Visual Feedback: LED status indicators provide immediate confirmation of power and the state of the timing cycle, aiding in troubleshooting.

• Compact Design: Saves valuable space in control panels compared to larger, older electromechanical timers.

Application Cases in Key Fields

• Motor Control Centers (MCCs: Used for implementing star-delta starting sequences, where the UT150-1 provides the precise delay between switching from star to delta configuration.

• Industrial Automation Sequences: Controls timing in automated assembly lines, such as delaying the start of a conveyor after a packaging operation or managing dwell times in machining processes.

• HVAC and Building Management: Manages pump sequencing in heating systems, controls fan delay after heater shutdown, or provides off-delays for ventilation in commercial buildings.

• Lighting Control: Used for staircase lighting, where the timer provides an off-delay to automatically switch lights off after a preset period.

Comparison with Competing Products

When compared to timer relays from other major manufacturers like Siemens (3RP), Schneider Electric (TeSys T), or Eaton, the ALSTOM UT150-1 offers comparable core timing functionality and reliability. Its primary advantage is its alignment with Alstom’s broader system specifications and its historical use in panels originally designed with Alstom components. Competing products may offer features like digital displays, more timing functions in a single unit, or network connectivity. However, for maintaining legacy systems, fulfilling specific project specifications that call for OEM parts, or ensuring guaranteed form-fit compatibility in existing Alstom-centric panels, the ALSTOM UT150-1 remains the specified and lower-risk choice.

Selection Suggestions and Precautions

• Verify Timing Function: Confirm that the timing mode (e.g., On-Delay, Off-Delay) indicated by the “-1” suffix matches your application’s requirements.

• Check Voltage Ranges: Ensure the module’s supply voltage range (e.g., 24-240V AC/DC) is compatible with your panel’s control voltage. The operating voltage must be within this range for proper function.

• Confirm Time Range: Verify that the adjustable time range of the ALSTOM UT150-1 covers the specific delay period you need for your process.

• Output Contact Rating: Match the relay’s output contact rating (current and voltage) to the load you intend to switch (e.g., a contactor coil). Do not exceed the specified ratings.

• Wiring and Mounting: Follow the manufacturer’s wiring diagram precisely. Ensure it is mounted securely on a DIN-rail in a well-ventilated part of the panel.

• Source Authentic Components: To ensure performance and safety, procure the ALSTOM UT150-1 from authorized distributors or reputable suppliers specializing in automation spares to avoid counterfeit or inferior products.
