iD double pole junction box for connection of roller shutter contacts, wired doors, problem sensors etc. Contains opto-couplers to enable longer sensor wires. Often used to remedy problem circuits on iD CASTLE panels.
Note: These units utilise a high-spec opto-coupler to avoid problems with some black iD biscuits. Be aware that other makes of iD junction boxes experience problems with some black iD biscuits because they use a low-spec opto-coupler.
Unused stock, tested.
