DOLD multifunction timer relays with selectable time functions

A multifunction relay is a timer whose operating mode is chosen on the device itself, so one part number can cover many jobs and keep timing functions cost-effective. Available functions include flasher, cyclic timer, pulse former, start-up and shut-down relay, and on-delay and off-delay. If you are not sure which mode fits your circuit, describe it to us and we'll help you set it up.

Most units set function and range by rotary switch. The 17.5 mm IK 7817N/200 and SK 7817N/200 and the 22.5 mm MK 7850N cover 0.02 s to 300 h at AC/DC 12 ... 240 V and have an input to interrupt or add time; MK 7850N adds a second changeover contact that can act as instantaneous. RK 7817 comes in dual- and single-voltage versions with UL approval, and BC 7935N offers 10 ranges up to 300 h.

For other needs, the MK 7830N is a digital timer with two separately settable times from 0.02 s to 9999 h. The EO 9920/200 is programmed on the front for on-delay, release delay and fleeting functions with 2 changeover contacts, and the 52.5 mm SN 7920 lists DIN EN 50155 and high DC switching capacity, with 1 NC + 2 NO delayed contacts.
