The 85 series relay is a panel mounted, screw terminal, open style sequencing relay. This two pole relay has a single coil which operates a ratchet wheel. Control cams, on the ratchet wheel shaft, step from one position to the next on each impulse to the coil. A 50 millisecond pluse will step the relay. Coils are for momentary duty only. The 85 series may be supplied in any sequence up to 12 steps. Contacts are single throw.

For Additional Configuration please contact the manufacturer.
