Selection Notes
The illuminated ring gives a visual confirmation that the 24 V AC/DC supply is live and the station is armed, which the plain XALK178 does not provide. Choose this E-variant for 1NO+1NC output; where a second NC circuit is needed from the same illuminated ring, the XALK178W3B140G adds a third contact.
