Opto 22 120D10 DC Control Solid State Relay, 120 VAC, 10 Amp, 4000 V Optical Isolation, 1/2 Cycle Maximum Turn-On/Off Time, 25 - 65 Hz Operating Frequency

Key features

• Solid state relay for fast response and high vibration resistance
• Panel mount for attaching to a conductive panel or heat sink
• Zero-voltage switching to reduce arcing and extend the life of the device
• Built-in snubber for preventing arcing across contacts
• UL Recognized for safety, CSA and CE certified for quality assurance

This Opto 22 120D10 solid state relay provides faster response time than an electromechanical relay and resists vibration. The panel mount requires the use of a thermal interface material such as a pad or compound (not included) placed between the back of the relay and the conductive panel or heat sink and is attached with screws (not included). On the front of the relay, four terminal screws attach control and load wires. The diode has an optical isolation of 4,000 VAC, and the device has a voltage rating of 120 VAC and a current rating of 10 amp. It has zero-voltage switching to reduce arcing and to extend the life of the device, with a maximum 1/2 cycle turn on/off time. It also has a built-in snubber for preventing arcing across contacts. This solid state relay is suitable for use in industrial process control applications such as temperature control, motors, lamps, solenoids, valves, and transformers, among others.
