Information

This Harmony XAL, single contact block uses screw-clamp terminals and has 1 x NC contact. It is compatible with Harmony XB5 control and signaling units and XAPS control stations. This contact block allows fast and easy replacement and configuration of your push buttons and selector switches. It is easily installed and replaced on XB5 complete push-button units and selector switches and XAPS control station and connects to control circuits with simple screw-clamp connections. It protects operators from unexpected contact with live circuits thanks to its IP20 protection index. Simple modular design facilitates post installation servicing, modification and adaption of machines by non-specialists. 1 million cycle high endurance allows less maintenance and damage in your installation. Vibration resistant screw clamp connection terminals ensure high vibration resistance making product suitable installation on high impact machine.
