南平LYK Series Digital Signal Isolator

Suitable for receiving switch or proximity switch inputs from the field, with isolated output relay contacts. Each channel can be independently configured for either in-phase or out-of-phase control of input and output, and it also features an input line fault detection and alarm indication function.

Product Description

Product Overview Product overview

The LYK series digital signal isolator converts input switch signals or proximity switch signals into relay or transistor signals via isolation, while ensuring complete electrical isolation among the power supply, input, and output.
