Sensata / Crydom M SERIES Series Interface Relay Module, PCB Mount, 5V dc Coil, 18mA Load

Need to make sure your equipment powers through emergency conditions? This interface relay module from Sensata | Crydom has got your back. It combines an optical isolation of 4kV with surge protection to provide a clean output that you can use to power heaters, motors and lamps. A current rating of 3A means it's just the thing for use in low-power systems. Through-hole mounting ensures a secure connection to your PCB, even when things get shaky.

• Wide operating temperature range of -30°C to +80°C for use in demanding environments
• Maximum turn-on time of 0.1ms for rapid-fire switching

Optical isolation involves converting the incoming electrical signal into a light signal using an LED. A light-sensitive component such as a photodiode then reverses the process to provide a clean electrical supply to your devices. The light signal acts as an effective barrier between the input and output electrical signals, protecting components from overvoltage or transient voltages in the power supply.
