PASS BOX CONTROLLER

Pass Box is used for material transfer from one Clean room to another clean room. It consists of a rectangular box with two doors. The two doors are interlocked such that both doors cannot be open at the same time, to prevent pressure losses and cross contamination.

Radix Pass Box Controller DXC421 achieves this by ensuring that before Door 1 of a Pass Box is opened, the Door 2 is closed. There are two LCD Display Cum Operator Panels (LCD Display Panels), one each to be mounted above each door. The panel has a 2 x 16 backlit LCD, information and status display for UV Time Totaliser, Door Status, etc. The LCD is also used during configuration of DXC421.

DXC421 also has provision to connect UV lamp, CF lamp and FAN.
