TIMERS AND MODULAR PROTECTION

Product catalog summary
Overview
This document is a technical catalogue from EL.CO. S.r.l. detailing modular timers and protection relays. It includes specifications, features, and technical data for various series of timers and relays.
Modular Timers
  • Compact Size: All timers are compact, occupying 1 module (17.5mm).
  • Universal Power Supply: Operates on 24-110VDC/24-240VAC.
  • DIN Rail Mounting: Designed for easy installation on DIN rails.
  • Multi-Scale and Multi-Function: Offers various time scales and functions.
Specific Timer Series
  • TEMSA Series: Programmable asymmetrical timer with a time range of 0.2 seconds to 20 hours, featuring a green LED for power indication and a red/green LED for output indication.
  • TEMS Series: Multi-scale timer with a time range of 0.1 seconds to 10 days, featuring a green LED for power indication and a red LED for output indication.
  • TEMFS Series: Multi-function timer with 10 selectable functions and a time range of 0.1 seconds to 10 days.
  • TESD Series: Star-delta timer with specific models for different voltage levels (115, 240, 415 VAC), featuring a time delay for start and transition.
Modular Protection Relays
  • Compact Size: All relays are compact, occupying 1 module (17.5mm).
  • DIN Rail Mounting: Designed for easy installation on DIN rails.
  • Phase Sequence and Monitoring: Includes relays for phase sequence, voltage, and current monitoring.
  • Liquid Level Control: Relays available for monitoring liquid levels.
Technical Data Highlights
  • Power Supply: Universal supply for both DC and AC voltages.
  • Rated Load: Maximum rated load of 2000 VA for AC1 applications.
  • Contact Life: Electrical life of 20 million operations and mechanical life of 100,000 operations.
  • Protection Degree: IP 20 or IP 40, depending on the model.
  • Operating Temperature: Ranges from -10°C to +50°C.
Standards Compliance
The products conform to various EC standards, ensuring reliability and safety in operation.
Power Supply and Relay Specifications
Power supply indication is shown by a green LED. The output relay can handle a maximum load of 2000 VA (AC1) with a rated current of 8A and operational voltage of 250 VAC/24 VDC. The contact life is 20 million electrical operations and 100,000 mechanical operations. Inrush current is 10A for less than 3 seconds. Minimum switching load is 5VDC at 10mA. Output indication is shown by a red LED.
General Features
Factory-set hysteresis is +/- 2% of the trip level. Response time is 100 ms, with a time adjustment range of 0.2 to 10 seconds. Power-on delay is 1 second. Operating temperature ranges from -10°C to +50°C, and storage temperature from -30°C to +70°C. The device has an isolation voltage of 4 kV and a protection degree of IP 40. It supports relative humidity up to 95% and weighs 60 grams. Dimensions are 98 x 17.5 x 64 mm. It complies with EC standards and is designed for DIN rail mounting.
Voltage Monitoring and Control
The device monitors its own supply and detects if one or more phases exceed set over-voltage trip levels. It measures phase-to-phase voltage and allows adjustment for under-voltage trip levels and time delay from over-voltage conditions. It is suitable for controlling over-voltage and phase sequence, with specific models addressing phase failure and neutral loss.
Liquid Level Control
The LVE24/LVE230 series is designed for controlling conductive liquid levels. It features adjustable sensitivity from 2.5K to 50K, automatic resetting, and supports up to three probes. The maximum cable length varies with sensitivity settings. It is suitable for maintaining maximum and/or minimum levels of conductive liquids.
Motor Protection Relay
The MPR24/MPR230 series provides motor protection with PTC sensors. It supports both manual and automatic reset, and includes a sensor test function. The relay operates with a power supply of 24VAC/DC or 90-264VAC and is designed for DIN rail mounting. It complies with several EN standards and features a compact size of 17.5 mm module width.
