Technical Specifications
Model XVC772 A102. Order number 3BHE032285R0102. 16 single-ended voltage inputs 0 to 10 V DC. Resolution 16 bit. Accuracy plus minus 0.1 percent full scale True C1. Isolation 1500 V AC channel-to-channel and field-to-system, dual-layer. S800 bus 10 Mbps. Hot-swap TM I/O Safe. Auto temperature drift calibration. Operating temperature -25 to plus 70 C. Dimensions 60 mm by 125 mm by 120 mm. Conformal coat. Certifications CE, UL, IEC 61131-2, IEC 61326. Some listings add 4 to 20 mA and RTD support on extended variant.
Functional Features
Per-channel open-wire, over-range and hardware fault diagnostics. Live insertion without loop disruption. Native Control Builder M plug-and-play. HART pass-through on HART variant. Software-visible sensor trim and fault codes.
Application Scenarios
Power generation turbine vibration and stator temperature. Boiler drum level and flue gas O2 in thermal plants. Reactor temperature and tank level in petrochemical. Fermenter pH and dissolved oxygen in pharma. Pump station pressure in water treatment.
Material and Structure
S800 I/O card, metal front plate, 16-channel ADC array, opto-isolated bus interface, LED per module, gold backplane fingers.
Working Principle
Field 0 to 10 V applied to input, precision ADC converts to digital, module tags value with channel status, publishes to S800 bus mapped to AC 800M memory, auto-calibration compensates zero and span versus temperature.
Installation Requirements
Insert into S800 I/O rack with correct terminal base, shield field cables to cabinet ground, separate from power wiring, keep bus terminator installed.
Usage Notes
Voltage-only variant, for 4 to 20 mA use 250 ohm shunt or AI current module. Do not exceed 10 V DC per channel. Verify True C1 accuracy class in Control Builder channel configuration.
