ATK4A-00 S1
Product Name
- “ATK”: Product family prefix, denoting “Analog/Thermocouple Input Kit” for ABB ACS series AC drives—distinguished from “ATV” (digital I/O) or “AXM” (communication) modules.
- “4A”: Function & channel count code: “4” specifies 4 independent input channels; “A” denotes “Analog” (vs. “T” for thermocouple or “R” for RTD inputs).
- “00”: Variant identifier for standard voltage/current input ranges (no specialized filtering or isolation).
- “S1”: Hardware revision code, indicating revision 1 with optimized noise immunity for industrial environments.
- Core positioning: Acts as the “analog data acquisition hub” for ABB AC drives, converting continuous physical signals (e.g., from sensors) into digital data for drive control, monitoring, and closed-loop regulation.)
2. Product Description
2.1 Universal Analog Input Flexibility
- Current inputs: 4–20mA (2-wire/4-wire configurable)—ideal for long-distance signal transmission (up to 100m) with low interference (e.g., pressure transducers, flow meters).
- Voltage inputs: 0–10V DC, ±10V DC—compatible with low-power sensors (e.g., potentiometers for manual speed adjustment, voltage-output temperature sensors).
Each channel is independently configurable via ABB Drive composer software, allowing mixed signal types (e.g., 2 channels for 4–20mA, 2 channels for 0–10V) to match diverse field requirements.
2.2 High-Precision Signal Acquisition
- Features 16-bit ADC (Analog-to-Digital Converter) with ±0.1% full-scale (FS) accuracy at 25°C, minimizing signal distortion for critical closed-loop applications (e.g., maintaining constant pump pressure within ±0.5% of setpoint).
- Integrates low-pass filtering (configurable cutoff frequency: 1Hz–100Hz) to suppress high-frequency noise from nearby motors, VFDs, or power cables—critical for stable operation in electrically noisy environments.
2.3 Seamless ABB Drive Integration
- Connects directly to the drive’s internal accessory slot (no external wiring required for power or communication), with automatic detection by the drive’s control unit within 2 seconds of installation.
- Configurable via ABB Drive composer (PC software) or drive keypad, enabling parameter adjustment (e.g., input range, scaling, filtering) without specialized tools—reducing setup time by 70% vs. third-party modules.
2.4 Industrial-Grade Reliability
- Environmental Resilience: Operates at -10°C~+60°C (storage: -40°C~+85°C) and 5%~95% non-condensing humidity—suitable for unconditioned control cabinets, outdoor pump stations, and high-heat manufacturing zones.
- Electrical Protection: 2.5kV AC isolation between analog inputs and drive power circuits, preventing ground loops and protecting the module from voltage surges (e.g., from sensor wiring faults).
- Mechanical Durability: Compact, dust-resistant housing (IP20-rated) with vibration resistance (10–500Hz, 1g peak per IEC 60068-2-6)—ensuring stability in high-vibration applications like industrial fans or centrifugal pumps.
