The 856-IS-DP provides a barrier between RS485 and RS485-IS to interface Standard Profibus DP and Intrinsically Safe Profibus DP.

With two IS channels it enables two BIM modules to operate in redundant mode and will support up to 13 MTL8000 1/1 nodes on the segment.

The 859-PL-DP connector (see 856-IS-DP datasheet) is designed for use on the IS Profibus side of the interface and can provide appropriate termination at that end of the segment. Pull-up and pull-down resistors are available in the 856-IS-DP for biasing where necessary.
