This Opto 22 Z240D10 solid state relay provides faster response time than an electromechanical relay and resists vibration. The diode has an optical isolation of 4,000V for insulating the circuits, and the device has a voltage rating of 240 VAC and a current rating of 10 amp. It has push-on, quick-connect terminals for high-volume applications. It has zero-voltage switching to reduce arcing and extend the life of the device. This relay is UL Recognized for safety, CSA and CE certified for quality assurance.

Relay switches (also called an electrical relay or an electrical relay switch) use a small amount of power to control a larger source of power connected to electrical devices such as car motors, computers, and lighting installations. A basic relay switch has a control circuit with an electromagnetic coil and a load circuit with contacts and a lever. When current flows into the relay switch, it moves through the coil and a magnetic field is created, which causes the lever in the load circuit to move between contacts, either turning the device on or off. In a normally open (NO) relay switch, when power is supplied to the relay, the load circuit is closed and the power source connected to the relay is turned on. In a normally closed (NC) relay switch, when power is supplied to the relay, the load circuit is open and the power source connected to the relay is turned off. In other types of relay switches, non-moving parts such as transistors or semiconductors can be used as the control circuit to operate the switching mechanism. Relay switches can be controlled with an external switch, such as a light switch, or they can be connected to an automatically switched power source, such as a car ignition. One relay can operate multiple switches, and multiple relays can be operated with a single switch, with each relay operating independently from the other relays in the system.
Opto 22 manufactures controllers for automating equipment, input/output (I/O) systems, solid-state relays, and software products that link electric, mechanical, and electronic devices to networks and computers. The company, founded in 1974, is headquartered in Temecula, CA.

Perfect for my temperature control project. This is not a "cheapy" SSR - it is high quality. I like the panel mount ears, makes it easy to mount. Use 1/4 quick connects to make connections easy.

Needed a way to automatically turn on/off an older DVI-D plasma display connected to my receiver's HDMI output. Built a DIY 12vdc to 120vac control box to utilize the receiver's 12vdc trigger output to supply 120vac power to the panel only when a video source was selected. I selected the Opto 22 Z240D10Z because it supports a wide range 3-30vdc input and can handle most 120-240vac devices drawing up to 10 amps. The Opto 22 Z240D10Z works perfectly.
