Product Description

The Vemer memo DW E is a digital modular time switch designed for the management of electric utilities in time with maximum precision. It mounts in a 2-module DIN-rail container and features a large backlit display that shows date, time and relay status, supported by a clear text guide on the front. A sealable front cover and a rear cover allow access for battery replacement while helping to protect the keypad.

This daily/weekly time switch offers ON, OFF, PULSE (from 1 to 59 seconds) and HOLIDAY operating modes, with a single relay output that can be controlled automatically or via manual override, either temporary or permanent. A random switching function is available for the outputs, and the device automatically updates for summer time. An internal lithium battery provides back-up for programming, with low battery signalling and keypad lock by password for added security. The menu is available in five languages: Italian, English, Spanish, German and French.
