General Information

• Brand: Emerson
• Model: A6210
• Product Type: Analog Input (AI) Module (for DeltaV DCS)
• System Compatibility: Exclusively designed for Emerson DeltaV DCS (compatible with DeltaV v11.3 and later software versions). Works with DeltaV controllers (e.g., M-series, S-series) and DeltaV I/O racks.
• Core Function: Converts analog signals (voltage, current, thermocouple, RTD) from field sensors/transmitters into digital data readable by the DeltaV controller. Supports high-precision measurement and advanced diagnostic features to ensure process reliability.

Technical Specifications

1. Analog Input Configuration

• Channel Count: 8 independent differential input channels (isolated between channels to eliminate cross-interference).
• Supported Signal Types (configurable per channel via DeltaV Explorer software, no hardware jumpers):
  • Current: 4–20 mA DC (two-wire/four-wire transmitters), 0–20 mA DC, 0–10 mA DC.
  • Voltage: ±5 V DC, ±10 V DC, 0–5 V DC, 0–10 V DC.
  • Thermocouple: Type J, K, T, E, R, S, B, N, C (with integrated cold-junction compensation, CJC).

• Input Resolution: 24-bit ADC (analog-to-digital converter) – delivers ultra-high measurement precision for critical processes.
• Input Impedance: ≥10 MΩ (for voltage signals); ≤100 Ω (for current signals) – minimizes signal attenuation from field wiring.

2. Electrical Performance

• Measurement Accuracy (at 25°C / 77°F, ±0.05% of full scale (FS) unless specified):
  • Current (4–20 mA): ±0.02% FS.
  • Voltage (±10 V): ±0.02% FS.
  • Thermocouple (Type K): ±0.1°C (range: -100°C to +1250°C).
  • RTD (Pt100): ±0.05°C (range: -200°C to +600°C).
• Common-Mode Rejection Ratio (CMRR): ≥90 dB (at 50/60 Hz) – suppresses electrical noise from industrial power lines and motor drives.
• Power Supply:
  • Backplane power: 5 V DC (supplied by DeltaV I/O rack), typical current draw: 0.6 A.
  • Isolation power: 24 V DC (external, for signal isolation), typical current draw: 0.3 A.
• Isolation: 2.5 kVrms between channels, between channels and backplane, and between channels and power supply (per IEC 61010-1) – protects the module from field-side voltage surges and ground loops.

3. Physical & Environmental Specifications

• Dimensions: 101.6 mm (W) × 152.4 mm (H) × 38.1 mm (D) [4.0” × 6.0” × 1.5”] – fits DeltaV standard 1U I/O racks.
• Mounting: 19-inch rack-mounted (installs into DeltaV I/O chassis, e.g., DeltaV Electronic Marshalling Chassis).
• Operating Temperature: -40°C to +70°C (-40°F to 158°F) – suitable for extreme industrial environments (e.g., outdoor cabinets, high-temperature process areas).
• Storage Temperature: -40°C to +85°C (-40°F to 185°F).
• Humidity: 5%–95% RH (non-condensing) – resistant to moisture in chemical or offshore facilities.
• Vibration Resistance: 5 g (10–500 Hz) per IEC 60068-2-6 (sinusoidal); 10 g (100–2000 Hz) per IEC 60068-2-27 (random).
• Shock Resistance: 25 g (11 ms half-sine wave) per IEC 60068-2-27 (transient).
• Protection Class: IP20 (front panel) – designed for enclosed control cabinets (prevents dust ingress; not waterproof).

4. Safety & Compliance

• Certifications:
  • CE (EN 61326-1 for EMC immunity/emissions, EN 61010-1 for safety) – no interference with DeltaV system components.
  • UL 508 (industrial control equipment) – compliant for North American markets.
  • CSA C22.2 No. 14 (Canadian safety standard) – meets Canadian electrical codes.
  • ATEX/IECEx (optional variant: A6210-EX) – for use in explosive environments (Zone 2/22).

Key Features

1. Ultra-High Precision: 24-bit ADC and low-drift components ensure long-term measurement stability (drift <0.01% FS/year), critical for processes requiring tight control (e.g., pharmaceutical batch manufacturing, refinery distillation).
2. Flexible Signal Support: Each channel can be independently configured to different signal types (e.g., 4–20 mA, Type K thermocouple) via software, eliminating the need for multiple dedicated modules and saving rack space.
3. Advanced Diagnostics:
   • Built-in Self-Test (BIST): Automatically checks ADC, power supply, and isolation circuits on startup; sends fault alerts to the DeltaV controller for remote monitoring.
   • Field Device Diagnostics: Detects open/short circuits in RTD/thermocouple wires, overrange/underrange signals, and HART device communication errors (if paired with HART-enabled sensors).
   • Status LEDs: Dedicated LEDs for power (green), communication (yellow), and channel faults (red) – enable quick visual troubleshooting.
4. Hot-Swappable Design: Supports hot swapping in DeltaV redundant I/O racks – allows module replacement without shutting down the DCS, minimizing downtime for 24/7 operations.
5. HART Integration: Compatible with HART 7.0 protocol – enables bidirectional communication with HART-enabled field devices (e.g., pressure transmitters) for device configuration and health monitoring, without disrupting analog signal acquisition.
6. Electronic Marshalling Compatibility: Works with DeltaV Electronic Marshalling (EM) chassis – simplifies wiring by allowing remote configuration of signal routing, reducing installation time and wiring errors.
