On-off delay relay

WAGO Corp.’s 859 DIN-rail timer relay module offers on-/off-delay timer modes and multiple time ranges for diverse applications.


WAGO Corp.’s 859 DIN-rail timer relay module offers on-/off-delay timer modes and multiple time ranges for diverse applications such as switch and package de-bounce sensors.

The 6-mm 859 carries a top-mounted potentiometer for fine-tuning delay time without removing the unit from the DIN-rail. On-delay mode prevents simultaneous excess inrush currents by delaying machine startup. Off-delay mode enables auxiliary components, such as fans, to continue operating after machine shutdown.

The timer comes with electromechanical or solid-state relay outputs. Four standard time delay ranges from 0.2 seconds to 10 minutes. Optional time delay ranges of 2.0 seconds to 35 minutes are also available.

Input voltage ranges from 19.2 to 28.8 VDC; outputs are 6A/24 VDC (electromechanical) and 2A/24 VDC (solid state).

And terminal block housing with jumpering and Cage Clamp spring pressure technology ensures terminations are maintenance-free and vibration-proof for conductors AWG 28 to14.

WAGO is a Germantown, Wis. manufacturer of spring pressure connection technology.
