TURCK Inc. has expanded its Diagnostic Power Conditioner (DPC) system with a single segment redundant backplane that can combine two isolated power supply modules into one FOUNDATION fieldbus segment. The backplane includes an integrated diagnostic unit used to monitor the redundancy of the external bulk power supply along with the H1 power supply -- aiding in the availability of the H1 segment. System status is available via a relay contact. The backplane’s small footprint (113 mm high x 42 mm wide x 210 mm long) is designed for DIN rail mounting, and features separate connections for grounding and shielding. The cable shield may be connected via shield clamps or screw terminals. Three-pole screw terminals with flange connections are also available to connect the segment outputs.
