Time Delay Relay Is Fully Programmable

The requirements of critical timing applications are said to be met with the SWDC Series of ac and dc delay-on-make time delay relays. The relays feature a 10-position binary coded DIP switch and digital CMOS circuitry. Widely specified for use in power supply sequencing and industrial and process control equipment, the devices are suited for any application where specific operations need to be delayed or sustained for precise intervals. Other uses include alarm systems, industrial vehicles, HVAC and safety control equipment. The SWDC Series offer three standard timing ranges, ±1% repeatability, 10A at 240 vac rating, and operation over a -45°C to 105°C temperature range.
