The IGUIC-24JB provides the connection between one door and a standard 24 V IGUIC controller.
The junction box connects to the main controller using two RJ45 cables. Door-side equipment is then connected to clearly defined screw terminals within the junction box.
Typical connections include:
24 VDC door lock or maglock
Request-to-exit button
Red and green indicators
Door contact
Lock monitor
Break-glass or emergency-release device
Access-control release
Automatic-door interface
Programmable relay connections
One door interface is required for each door connected to an IGUIC4-24 or IGUIC8-24 controller. Individual IGUIC-24JB units are particularly suitable where the interfaces are installed locally near each door.
Additional features
Enclosure dimensions: 200 × 155 × 80 mm
