Key Features

• 8‑Channel High‑Density Input: Provides eight independent single‑ended analog input channels, reducing rack space and wiring complexity for multi‑sensor applications.
• 12‑Bit High Resolution: Delivers 4,096 discrete digital steps per input range, enabling precise detection of small signal changes for accurate process monitoring.
• Dual Voltage Range Support: Accepts both 0–10 VDC unipolar and ±10 VDC bipolar signals, compatible with standard industrial voltage transmitters and sensors.
• Enhanced Galvanic Isolation: Features 400 VDC channel‑to‑channel isolation and 1,000 VDC channel‑to‑ground isolation, eliminating ground loops and protecting control system electronics from high‑voltage transients.
• High Accuracy and Stability: Maintains ±0.1% full‑scale accuracy at 25°C with minimal drift over temperature and time, ensuring reliable long‑term measurement performance.
• Software‑Configurable Ranges: Allows selection of input voltage ranges via the system backplane BIU (Backplane Interface Unit), eliminating hardware jumper changes and simplifying system reconfiguration.
• Robust Noise Rejection: Incorporates common‑mode noise suppression and on‑board filtering to reject electrical interference from motors, VFDs, and other industrial equipment.
• Compact Industrial Design: Built with a rugged metal casing and conformal‑coated PCBs to withstand vibration, dust, and moisture in factory floor and outdoor installations.
• Seamless System Integration: Connects directly to GE Series 670 and Horner Field Control I/O racks, supporting high‑speed data exchange with PLCs, HMIs, and SCADA systems via the backplane bus.

Applications

• Process Industries: Monitors pressure, temperature, flow, and level sensors in chemical, petrochemical, pharmaceutical, and food and beverage processing plants.
• Power Generation: Acquires analog signals from turbine sensors, generator exciters, and boiler transmitters in thermal, hydroelectric, and cogeneration power stations.
• Manufacturing & Automotive: Supports assembly line monitoring, machine tool condition sensing, and robotic system feedback in automotive, aerospace, and general manufacturing facilities.
• Water & Wastewater: Measures signals from level, pressure, and flow transmitters in water treatment plants, sewage systems, and pumping stations for process control and regulatory compliance.
• Oil & Gas: Deployed in upstream drilling rigs, midstream pipelines, and refineries to monitor pressure, temperature, and vibration sensors for equipment protection and process optimization.
• HVAC & Building Automation: Integrates with temperature, humidity, and pressure sensors in large commercial buildings, data centers, and airports for climate control and energy management.
• Legacy System Upgrades: Serves as a direct replacement for older GE analog input modules in existing Series 670 installations, extending the life of legacy control systems while maintaining compatibility.

Additional Notes

• The HE670ADC830 is a core component of GE/Horner’s Field Control I/O ecosystem, widely used in legacy and retrofit projects across heavy industries.
• It is fully compatible with Horner’s OCS (Operator Control Station) and GE’s RX3i/PACSystems platforms, enabling mixed‑vendor system integration.
• For new installations requiring higher channel counts or digital communication, Horner offers modern analog input modules with Ethernet/IP and Modbus TCP interfaces, while retaining backward compatibility with the HE670ADC830 for spare parts and replacements。
