Latching / Sequencing Relays

85 Series
Screw Terminal Sequence Relays

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.

255 Series
Industrial Latching Relays

The 255 Series is a two coil latching version of the general purpose type 219 relay. When the operate coil is momentarily energized, contacts transfer and remain so even after coil power is removed. The second coil when momentarly energized, provides electrical reset of the contacts. All contacts operate from a common armature to prevent contatct overlapping. Coils are rated for continous duty. Both coils can be energized at the same time with no damage. The operate coil is dominant.

311 Series
Industrial Sequencing Relays

The 311 Series relays are sequencing (stepper) relays built on the industrial 219 style frame. Hold down clip is integral to the relay base. Double pole contacts transfer on energizing of coil or de-energizing. Dual cam movement allows contacts to operate together or separately. Works equally well with application of continous voltage to coil or energy saving impulse. No continuous voltage required for memory. Numerous custom switching arrangements are possible over 8 steps per revolution of the cams.
