A general purpose timer that offers good functionality along with the flexibility of its mounting options making it an ideal choice for many applications. The key programming feature enables away from site programming and uniform programming of multiple locations. Text based menu system and self explanatory symbols displayed on a large, back-lit dot matrix area to provide two high resolution text lines. Pulse programming allows you to set small bursts (e.g. school bells) in 1 second steps. The 23871 can be extremely quick and easy to program, it can be programmed with supply disconnected and has the ability to program via your computer using Sangamo's optional Easy Vue software and USB link (25195 - not supplied) and backed up or transferred via a programming key (25193 - not supplied). Can be mounted on a panel, surface or DIN rail (95587 Mounting Kit required) making this an adaptable timer for a variety of situations.
