Johnson Controls A70 Series Four-Wire, Two-Circuit
Johnson Controls A70 Series Four-Wire, Two-Circuit Temperature Control. Four-Wire, Two-Circuit Temperature Control. A70 Series. The A70 Series temperature control incorporates a vapor-charged sensing element. The A70G, A70H, and A70K have a 4-wire, 2-circuit contact block that contains two isolated sets of contacts.
Johnson Controls A70 Series | Low and High Heavy Duty
The A70 Series heavy-duty temperature-limit controls incorporate a vapor charged sensing element. A70G, A70H, and A70K have a four-wire, two-circuit contact block that contains two isolated sets of contacts. The contacts are designed to transfer at set point so that when the main contact opens, the auxiliary contact closes simultaneously.

How to Construct Wiring Diagrams | Industrial Controls
Wiring diagrams help technicians to see how the controls are wired to the system. Many people can read and understand schematics known as label or line diagrams. This type of diagram is like taking a photograph of the parts and wires all connected up. These diagrams show the actual location of parts, color of wires, and how they are connected.
