KS3002

The KS3002 module by Beckhoff is a robust member of the KS Digital Input Modules series, designed for precision signal acquisition in demanding industrial environments. It provides 2 inputs with signal voltage range of -10 +10 V and features an internal resistance exceeding 200 kilo-ohms to prevent circuit loading. Housed in a compact polycarbonate enclosure measuring 12 mm (W) × 100 mm (H) × 68 mm (D), it mounts effortlessly on a 35 mm DIN rail in compliance with EN-60715. Power is supplied directly via the K-bus, minimizing external cabling and simplifying panel layouts. Optimized for industrial automation, the KS3002 ensures consistent performance under typical factory conditions.

In terms of technical capabilities, the KS3002 achieves a Conversion Time of approximately 2 ms, enabling swift response to changing inputs. The module delivers a Resolution of 12 bit (11 bit for the 0 – 10 V range) and maintains a Measurement Error/uncertainty of less than ±0.3% relative to full-scale value. It supports a Bit Width In The Process Image of 2 × 16 bit data with optional 2 × 8 bit control/status words. With a Common-mode Voltage Ucm tolerance of up to 35 V and a typical Current Consumption on the K-bus of 65 mA, the KS3002 balances low power draw with high signal integrity. The module’s differential input circuitry, combined with its high internal resistance, ensures accurate acquisition of analog signals across the full voltage range.

Operationally, the KS3002 meets rigorous safety and performance standards, holding Approvals/markings including CE, CCC, UL, ATEX, and IECEx certifications. It operates reliably across a temperature span from -25 °C to +60 °C and can be stored safely between -40 °C to +85 °C, ensuring durability in harsh conditions. The polycarbonate housing incorporates spring-actuated connectors compatible with ferrule-ended, flexible, or solid conductors, enabling tool-free wiring and rapid maintenance. Visible signal LEDs provide immediate status feedback, facilitating quick troubleshooting in live systems. Side-by-side mounting via a double slot and key connection guarantees seamless mechanical and electrical continuity between adjacent terminals.

Integration into existing automation architectures is straightforward: the KS3002’s power supply via the K-bus reduces wiring overhead, while DIN rail mounting simplifies panel design. It interfaces natively with a variety of fieldbus systems and couplers, including CANopen, CANCAL, DeviceNet, ControlNet, Modbus, RS232, and RS485, ensuring flexible deployment across numerous control platforms. Ideal for machine building, process control, and remote I/O applications, the KS3002 enhances system modularity and scalability with minimal engineering effort.
