HN800 is the redundant, 4.0 MBps IO bus of the Symphony Plus DCS SD Series system. Electrical HN800 bus is made up of horizontal (row) or vertical (columns) bus segments. Horizontal row mount bus segments are comprised of SD Controllers (SPCx00), SD Series I/O and communication moduled mounted between cHBX01L (left side) and cHBX01R (right side) bus eXtenders. The cHBS01 Compact Horizontal Bus Spacer mounts between IO modules within a row and is specifically designed to create a 45mm space for field signal wiring.
cHBS01 has no active components. It is only intended to provide space for field signal wiring in horizontal rows.
