The Ocean Controls KTA-258 is a 4 channel opto-isolator with the ability to take signals from NPN, PNP, dry-contact and push-pull type sensors and present isolated NPN or PNP-style outputs. Each channel has a switch for selectable input and output configurations.

The card can be used to convert PNP sensors for use with NPN style inputs on a PLC or vice-versa. A 1,000 V isolation barrier between input and output sides prevents ground loops and electrical noise from coupling into your control system.
