Product & engineering

Understand the product.

PhotoMOS Optically Isolated Relay is a component that transfers electrical signals between two isolated circuits by using light. A PhotoMOS Optically Isolated Relay is a semiconductor relay with an LED as an input and MOSFET as an output. It is used in various fields to improve device reliability and reduce size. PhotoMos Optically Isolated relays find their use in the area of telecommunication, measurement & instrumentation, security devices, industrial control, Power Storage System and Medical Device. The input pins are connected to a light emitting diode which emits infrared light as soon as energized. Below the LED is an optoelectronic device that switches the output transistors. The whole unit is molded in translucent resin providing a galvanic separation between input and output.

Output resistance, capacitance, leakage and voltage range affect the signal path; optical isolation alone does not determine measurement accuracy.

What turns activity into demand

Switching requirements translate into poles, load duty, isolation and control interfaces. Replacement decisions also depend on contact wear, operating cycles and the surrounding protection circuit.

The commercial boundary

Mechanical-contact and semiconductor relays have different loss and failure behaviour. Coil supply or package similarity alone does not establish interchangeability.

What limits reliable small-signal switching?

Output resistance, capacitance, leakage and voltage range affect the signal path; optical isolation alone does not determine measurement accuracy.
