Multi-Functioning Relays

Multi-Fuction Relay

Model 68-1

The Series 68 Nuilmatic Multi-Functioning Relays are used to measure and control circuits to perform general functions, such as totalizing, accelerating, averaging, subtracting, amplifying, and reducing. As such, they provide excellent solutions to many control problems involving feedforward, computing, interlocking, and multi-element circuits
