The C85 Series Relay
is a base 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 pulse will step the relay. Coils are for momentary duty only. The C85 may be
supplied in any sequence up to 12 steps. Contacts are single throw.
