General Description

First introduced in 1991, the Series 9000 INTRINSPAK has quickly become the industry standard for intrinsic safety barrier design. Within the series the user can choose from the Type 9001 single channel, Type 9002 dual channel, or for applications requiring up to 3/4W of power, the Type 9004 single channel with electronic current limitation.

All three types share a common 1/2" wide housing which snaps directly to a 35mm DIN rail. Once mounted, an electrical connection is formed between the barrier and the rail. This rail now serves as the intrinsic safety ground bus when connected to the designated grounding point. Two additional ground lugs are provided and may be used as a redundant grounding method or for terminating shields.

Each barrier also contains a replaceable 160mA fuse cartridge for each channel. This fuse is located within the front faceplate and protects the barrier from pole reversal and voltage spikes at the input side (terminals 1 and 2). Unlike other safety barrier designs, this fuse will not blow should the field wiring be shorted to ground.

Safety barriers are polarity sensitive devices. Therefore they are available in +DC, -DC, and AC voltage ratings. They also contain an internal resistance which may cause loading problems in some applications. STAHL safety barriers have been designed to minimize this resistance and offer the lowest available ratings in the industry.
