Selection Notes
The added 1NO contact lets this key-release station feed a status signal back to a controller while the 1NC breaks the safety circuit, the same logic that separates the turn-to-release XALK178E from the base XALK178. Where only a safety 1NC is needed with key release, the XALK188 covers it.
