Abb Ct-mfe Multifunction Time Relay 1Svr550029R8100 0.05S-100H

The ABB CT-MFE (1SVR550029R8100) is a superior multifunction electronic time relay suitable for highly industrialized and demanding applications such as industrial control panels. Made by ABB Stotz-Kontakt GmbH, Bulgaria, the ABB CT-MFE relay has many timing functionalities integrated in one device, thus making the use of different relays unnecessary. The ABB CT-MFE relay features an incredibly wide timing range, which extends from 0.05 seconds to 100 hours in addition to featuring AC/DC voltage 24-240 V. Conforming to international standards IEC/EN 61812-1 & IEC/EN 60947-5-1, the ABB CT-MFE time relay is used widely by engineers around the world due to its reliability.

Key Features:

1. Wide time span: Ranges from 0.05 second to 100 hours within a single timer model and eliminates need for using several models of timing relays for performing short cycle and long cycle timing applications.

2. Various time function: Provides on delay, off delay, pulse and many other options which can be selected with the help of a front panel switch.

3. Universal power supply: Runs with AC/DC voltages ranging from 24-240 volts at a frequency of 50/60 Hz.

4. Single C/O output: Has an SPDT contact rated with 4 amps current (Ithe), 300 volts of Ui and impulse withstand voltage of 4 KV.

5. Electrical endurance: Rated for 3 A / 230 V in AC-15 and 2 A / 24 V in DC-13 — high electrical endurance for inductive loads during switching operations.

6. DIN rail mountable: Housing dimensions 5 × 4 × 4 inches in B 300 series, which can be easily mounted on DIN rail mounting facilities in an industrial control panel.

7. Compliance with international standards: ABB relay meets international standards including IEC/EN 61812-1, IEC/EN 60947-5-1, and GB/T 14048.5 and therefore can be installed anywhere in Europe, Asia, and the rest of the world without seeking further approvals or certifications.

8. Lightweight yet strong: Weights just 90 grams and strong enough to operate in industrial settings according to the ABB design specifications.

Application:

1. Automation in industry and PLC panels: Applies to control panels used in automated processes that regulate the start-stop time delay for motors, conveyor belts, and actuators.

2. Control of motors and star-delta starters: Determines the switch time from one state to another for star-delta starters, lowering inrush currents when starting up compressors, pumps, and fans.

3. HVAC and building management systems: Regulates timed cycles for ventilation systems, fan delays, and protection delays for compressors in heating, ventilation, and air conditioning applications.

4. Conveyors and production lines: Coordinates the timing of conveyor belts and other machines on the production line to ensure smooth operations without collision.

5. Control of lighting and signboards: Automatically controls timed operation cycles of industry lighting, advertisement panels, and staircase lights with a wide time range, which can be extended up to 100 hours.

6. Compressor and pump protection: Protects compressors and pumps from short cycles through delayed start times, hence increasing their life span.

7. Safety and alarm systems: Produces timed alarm pulses in fire, security, and process alarm panels to ensure that alarms run for prescribed periods and are handled correctly.

8. Water treatment plants: Operates dosing pumps, aerators, and filters in the treatment cycle of wastewater treatment and purification plants.
