Timers and digital time relays

Timers and digital time relays are essential components in modern electrical systems, providing automated control and enhanced functionality for various applications. Timers allow for precise time-based control of devices, ensuring actions occur at specific intervals. Digital time relays offer advanced features, including multiple time functions, programmability, and precise control over switching operations.

• Multifunction Time Relay with Supply Voltage Disconnection (CRM-72TO):
  • This relay ensures timing continues even after power disconnection, making it suitable for backup power systems and emergency applications. It offers a time delay range from 0.1 seconds to 10 minutes, adjustable through a rotary switch.

• Multifunction Time Relay (CRM-91H, CRM-93H):
  • These relays provide versatile time-based control with 10 functions, including time functions controlled by supply voltage and control input, and a memory (latching) relay function. They support a time scale from 0.1 seconds to 10 days, divided into 10 ranges, and feature user-friendly function and time settings via a rotary switch.

• Time Relay (CRM-2H):
  • This relay is designed for cyclic operations with two time functions: cycler starting with pulse and cycler starting with pause. It features a time scale from 0.1 seconds to 100 days, split into 10 time ranges, with rough time setting through a rotary switch.

• Delay ON Star/Delta Relay (CRM-2T):
  • This relay generates motor starting cycles for star-delta configurations. It provides adjustable time settings for both the star (t1) and delay (t2) phases.

• Digital Time Switch (SHT-1, SHT-1/2):
  • These switches provide daily, weekly, monthly, and yearly program capabilities. They feature automatic summer/winter time conversion, 100 memory locations, and a clear LCD display.

• Digital Time Switch (SHT-13/2):
  • This all-in-one digital time relay offers a wide range of programs, including daily, weekly, yearly, astronomical, mixed, and random. It has a built-in web server for setup via Wi-Fi and supports time synchronization through an NTP server.

• Analog Electromechanical Time Switch (APC-D1, APC-DR1):
  • These switches control electrical installations based on daily programs, with or without battery backup. They feature a manual switch with a permanent ON position and offer a simple dial time setting with a minimum switching time of 15 minutes.

• Mechanical Time Switch (ATS-1DR):
  • This switch offers a cost-effective alternative to digital time switches, suitable for controlling heating, ventilation, cooling, lighting, or pumps. It features a daily program and operates based on real time, with a power reserve of up to 100 hours.

• Multifunction Relay (SMR-T, SMR-H, SMR-B):
  • These relays are designed for installation in wiring boxes and offer various functions, including time-based control, memory relay operation, and control via an independent input.

• Time Switch (ASTROCLOCK-2):
  • This time switch features two independent programmable output contacts and supports 40 daily and weekly programs. It includes astronomical or fixed-time maneuvers, automatic summer/winter time switching, and a backup power supply.

• Digital Time Switch (ETICLOCK-R1):
  • This digital time switch controls electrical installations with various operations, including ON/OFF, short-term operations, pulses, and repetitive cycles. It features automatic DST changes, 4 holiday periods, and adjustable screen brightness.
