The ABB XZC826A102, also cataloged as part number 3BHE036348R0102, serves as a 4-channel input to 8-channel output signal splitter board for dual-path process signal replication and galvanically isolated distribution across ABB Advant OCS and System 800xA architectures.

Model Configuration

Ordering Code and Variant Identification

• Part Number / Catalog Number: 3BHE036348R0102
• Model Designation: XZC826A102
• Signal Splitting Ratio: 1:2 splitting configuration (4 configurable input channels mapped to 8 isolated output channels).

Hardware Specifications

Signal Conditioning and Isolated Distribution Architecture

Engineered for dual-path instrumentation loops, the XZC826A102 splitter board duplicates incoming analog or digital signals without loading down the primary control loop. Accepting up to 4 configurable input channels (4-20 mA, 0-10 V, or digital levels), the unit replicates each signal across 8 output channels in a precise 1:2 ratio. Operating on 24 VDC (+/-10%) with a power draw under 2 W, it provides 1500 VAC galvanic isolation between supply, input, and output circuits. A 10 kHz signal bandwidth, sub-millisecond response time (<1 ms), and full-scale accuracy of +/-0.1% ensure high-fidelity signal transmission for parallel monitoring, recording, or redundant control applications.

Installation and Wiring Considerations

• De-energize all 24 VDC power supplies and field instrumentation loops before mounting or making terminal connections.
• Verify input signal configurations (4-20 mA, 0-10 V, or digital) against field device outputs prior to applying power.
• Maintain proper separation between low-level signal cables and high-voltage AC or inductive load wiring to preserve the 10 kHz signal bandwidth and +/-0.1% FS accuracy.
• Ensure cabinet ambient temperatures remain within the specified operating envelope of -20 deg C to +70 deg C with non-condensing relative humidity below 95%.
• Ground the system enclosure in accordance with ABB grounding guidelines to maximize 1500 VAC isolation and surge immunity.
