Overview
The Allen-Bradley 700-HC24Z24 Series B is a 4-pole miniature ice cube relay optimized for general-purpose industrial switching and control applications. Bulletin 700-HC Miniature Square Base Relays are 4-pole plug-in relays for low-energy switching applications. This compact, translucent relay features 24 V DC general ice cube relay specifications including four changeover contacts (4PDT) 7 A and silver contacts. Its plug-in design enables quick installation and replacement in standard relay sockets.
Key Features
- 4PDT Contact Configuration: 4-pole double-throw (4PDT) contact configuration with 24V DC coil, offering reliable control for signaling, automation, and switching applications.
- Compact Ice Cube Design: Plug-in relay from the 700-HC Series, commonly referred to as an “ice cube” relay due to its compact, translucent enclosure.
- Silver Contacts: Silver nickel contact material rated for 7 A contact rating.
- Plug-in Socket Mount: Plug-in socket compatibility for quick installation with standard 700-HN series relay sockets.
- Industrial Reliability: 100,000 electrical operating cycles with CCC, CE, CSA, CUL, KC, and UL certifications.
