Solid State Relays Common Precautions

■Application Circuit Examples

1. Connection to Sensors

The SSR connects directly to a Proximity Sensor or

Phot

oelectric Sensor.

2. Switching Control of Incandescent Lamps

3. Temperature Control of Electric Furnaces

4. Forward and Reverse Operation of Singlephase

Inductive Motors

Note 1. The voltage between the load terminals of either SSR 1 or SSR

2 when turned OFF is approximately twice as high as the supply

voltage due to LC coupling. Be sure to use an SSR model with

a rated output voltage of at least twice the supply voltage.

For example, if the motor operates at a supply voltage of 100

VAC, the SSR must have an output voltage of 200 VAC or

higher.

Note 2. Make sure that there is a time lag of 30 ms or more to switch

over SW1 and SW2.

* Resistor to limit advanced phase capacitor discharge current.

To select a suitable resistor, consult with the manufacturer of the

motor.
