Product Description:

The KL4031 model is known as an analog output terminal. It provides a differential signal voltage output ranging from -10 V to +10 V. The apparatus is engineered for small and resilient automation systems. This terminal is manufactured by Beckhoff. The electrical isolation between the Kbus and signal voltage is up to 500 V

The Beckhoff's KL4031 provides a single channel output with superior 12-bit resolution for precise processing. This falls under the KL series of analog input modules. It has a fast conversion time of about 1.5 ms for efficient operations. The gadget takes power from the K-bus with a typical current consumption of 75 mA. The process image displays the analog output with a width of 1 × 16-bit data and optionally 1 × 8-bit control. The module can withstand loads up to 5 kΩ and is short-circuit-proof. Temperatures in which KL4031 is operating are 0°C to 55°C. The weight of KL4031 is approximately 85 g. Power transfer is ensured by the maximum current load on power contacts of 10 A. The terminal is protected against shock and vibration as per EN 60068-2/27 standards. The design has a KS-12-8 pin terminal box with pluggable wire levels. It supports flexible wiring using solid or flexible conductors and ferrules. The KL-12-8pin has a stripping length of 8-9 mm and KS-12-8pin is 9-10 mm.

The Beckhoff KL4031 module provides a solid conductor connection of 0.08-2.5 mm² with ferrules up to 1.5 mm². The KS-12-8pin type allows up to 1.5 mm² for versatile wiring possibilities. The KL4031 supports side-by-side mounting using key connection method. It provides pluggable wiring for KSxxxx Bus Terminals. Get this analog output terminal today from Wake Industrial.

Frequently Asked Questions about KL4031:

Q: How does the 500 V electrical isolation in KL4031 improve system safety?

A: The 500 V isolation in KL4031 protects the control system from electrical surges and faults. This ensures stable and safe analog signal processing under demanding industrial conditions.

Q: Why is a 12-bit resolution important for the KL4031 analog output?

A: A 12-bit resolution in KL4031 enables finer voltage adjustments with minimal quantization error. It ensures precise signal representation for sensitive process applications.

Q: Why is the KL4031 suitable for side-by-side mounting with double slot and key connections?

A: The double slot and key system in KL4031 ensures secure and vibration-resistant installation. It simplifies wiring and module expansion on the DIN rail.

Q: How does the KL4031 optimize power efficiency without using power contacts?

A: KL4031 draws power directly from the K-bus instead of separate contacts. This reduces installation complexity and avoids additional cabling needs.

Q: How do approvals like ATEX and IECEx increase the value of KL4031?

A: The ATEX and IECEx certifications enable KL4031 to be safely used in explosive environments. This makes it suitable for oil, gas, and chemical processing industries.
