Intrinsic safety cassette KSI-1 (Industry)
CERTIFICATE:
Designed for installation outside the hazardous area, the intrinsic safety cassette is an auxiliary device used to install intrinsic safety barriers (e.g. BSI), which, in turn, are used to power equipment installed in potentially explosive atmospheres. The KSI-1 cassette is designed for installation in 19'' racks having the IP rating of at least IP20.

DESCRIPTION
Cassette consisting of a control device with 64-pin controllers, in a body made of aluminum profiles with auxiliary guides for installation of intrinsically safe barriers (push-on).
FEATURES/TECHNICAL SPECIFICATION
The cassette in the rear part has three corpses of connectors:
- intrinsically safe connectors for connecting intrinsically safe lines to receivers
- connectors on the non-intrinsically safe side intended for connecting the control panel line (or non-intrinsically safe automation)
- non-intrinsically safe power connector -48VDC

The cassette allows the removal and insertion of the barriers under voltage (Hot Swap)
If it is necessary to connect more barriers, multiple KSI-1 cassettes connected to one power supply (of appropriate power) can be used in a 19" cabinet.
