Description

The Renke RS-KB-1-N01-4-EX functions as a dedicated display and sensor interface unit, providing real-time visualization of environmental parameters. Its core sensing components deliver precise measurements, with temperature accuracy up to ±0.4°C and humidity accuracy up to ±2% RH, suitable for critical monitoring applications.

Engineered for industrial durability, the panel features a static LED display to eliminate flicker and ensure stable readability. The integrated RS485 interface with Modbus-RTU protocol allows for straightforward daisy-chaining and long-distance data transmission, making it ideal for integration into centralized building management systems (BMS), factory automation networks, and environmental monitoring stations.

Key Features

  • Large-Format Industrial Display: 22.4-inch LED digital tube provides excellent visibility from a distance and under varying lighting conditions.
  • Industrial Communication Standard: RS485 Modbus-RTU interface ensures reliable, noise-immune data transmission over distances up to 2000 meters.
  • High-Accuracy Sensing: Delivers precise environmental data with selectable accuracy classes for both temperature and humidity parameters.
  • Robust Mechanical Construction: Housed in a durable aluminum alloy frame with a protective acrylic panel, built for long-term use in demanding settings.
  • Low Operational Power: Consumes less than 0.8W, enabling efficient operation from standard 10-30V DC industrial power sources.
  • Real-Time Static Display: Prevents screen flickering for consistent, eye-friendly data presentation.
  • Optional Alarm Functionality: Supports configurable limit alerts for immediate notification of out-of-range conditions.
  • Wide Environmental Compatibility: Operates across a broad temperature and humidity range, suitable for diverse indoor industrial and commercial spaces.

Applications

  • Centralized environmental monitoring displays in manufacturing facilities and clean rooms.
  • Warehouse and storage area climate control system status panels.
  • Greenhouse and agricultural environment monitoring stations.
  • Laboratory and pharmaceutical storage area condition visualization.
  • HVAC and building management system (BMS) operator interface panels.

Frequently Asked Questions

What is the communication protocol and how do I connect this display panel to my system?

The panel uses a standard RS485 interface with the Modbus-RTU protocol. Connect the A and B data lines to your RS485 network master (e.g., PLC, SCADA system, or USB-to-RS485 converter). Ensure proper termination and use shielded cable for runs up to 2000 meters. The device supports daisy-chaining with other Modbus slaves on the same bus.

What power supply is required, and what are the wiring connections?

The unit operates on a 10-30V DC power supply, typical for industrial 12V or 24V systems. Connect the positive lead to the V+ terminal and the negative to the GND terminal. Polarity must be observed. The low power consumption (≤0.8W) minimizes load on the power source.

What is the difference between Class A and Class B accuracy specifications?

Class A represents the higher accuracy tier: ±0.4°C for temperature and ±2% RH for humidity under reference conditions (25°C). Class B offers standard accuracy: ±0.5°C and ±3% RH. The specific class of your unit is determined by the internal sensor component; refer to the device documentation or label for confirmation.

Can this display panel trigger an alarm if readings go out of range?

Yes, the RS-KB-1-N01-4-EX supports an optional alarm function. This typically involves configuring high/low limits via Modbus registers. When a monitored parameter (temperature or humidity) exceeds these preset thresholds, the unit can activate a visual alert on the display or signal an external device through its communication interface.
