A range of general-purpose timeswitches which provide a single output circuit. The range includes a simple 24-hour electro-mechanical model plus an electronic model which offers 7-day or 5/2 day operation.

All three units fit the GP wallplate and have an identical wiring configuration allowing systems to be upgraded without the need for rewiring. Please note this unit is for replacement purposes only (no backplate included)

The electro-mechanical 103 has a Timed Off Constant switch and a thumbwheel which allows early selection of future switching operations.All models show clearly the current state of the output.

 

Compatible alternatives with same backplate & wiring:
Danfoss Randall 103E (obsolete)
Danfoss Randall 103E5 (obsolete)
Danfoss Randall 103E7 - 7 day digital version of 103
