Step-by-Step Wiring Instructions

The wiring diagram for Deltrol Controls Relay S155D is straightforward, and with a few instructions, you can wire it up easily. Here are the step-by-step instructions for wiring S155D relay:

Step 1: Connect the Coils

The first step is to connect the coils to the power source. Take the coil with the positive connection marked, and connect it to the positive terminal of the power source. Take the other coil and connect it to the negative terminal of the power source.

Step 2: Connect the Switching Arm Assembly

The next step is to connect the switching arm assembly. Take the moving contact and connect it to the common terminal of the load. Take the stationary contact and connect it to the NO or NC terminal of the load, depending on the switch logic required.

Step 3: Connect the Terminals

The third step is to connect the wire to the screw terminals. Take the wire on the moving contact and connect it to the common terminal of the relay. Take the wire on the stationary contact and connect it to the NO or NC terminal of the relay, depending upon the switch logic required. Repeat the process for both sets of coils.

Step 4: Close the Enclosure

The last step is to close the enclosure and make sure it is securely fastened. This will protect the relay from dust, moisture, and other contaminants.
