• • • • • 1. Product Model & Basic Introduction

          Model: DSIH90K Keyboard Module (also designated as 5735 202‑A / DSIH90K)
          This module is part of ABB’s industrial control system accessories, functioning as a keyboard input interface for operator panels. It is intended for integration into large‑scale control or monitoring systems, allowing keystroke input, command entry and parameter adjustment by an operator.

          2. Technical Specifications

          • Model: 5735 202‑A / DSIH90K Keyboard Module.

          • Installation dimensions (example): approx. 460 mm (depth/length) × 290 mm (height) × 65 mm (width).

          • Weight (example): approx. 3 kg.

          • Environment: Panel / control‑cabinet mounting for industrial automation.

          • Structure: Industrial keyboard module, likely metal or ruggedized housing, with key‑input area and possibly status indicators.

          • Connections: Integrated into system control cabinet, via backplane or terminal connections (specific interface not documented).

          • System usage: Found as part of “TESSELATOR” series or “Master Control System” accessory modules.

          • Availability: The model appears to be less current, commonly found as spare/ex‑inventory parts.

          3. Advantages and Features

          • Dedicated industrial keyboard interface: Enables reliable operator input for commands and adjustments in automation systems.

          • Panel‑mount friendly size and form‑factor: Suitable for mounting in operator consoles or control cabinets.

          • Designed for complex control systems: Its usage in advanced systems (e.g., TESSELATOR) indicates suitability for demanding automation tasks.

          • Effective for maintenance/stock spares: Given limited public information and newer replacement parts, this module serves as a useful spare item in legacy systems.

          • Industrial grade robustness: By design expectation, the module supports frequent operator use and fits in industrial environments, contributing to system reliability.

          • Ease of replacement: Using a standard keyboard module component simplifies system maintenance and prolongs system lifecycle.

          4. Typical Application Areas

          • Operator control panels in power plants or large process control systems.

          • Panel‑mounted keyboard units in petrochemical, steel, manufacturing facilities automation systems.

          • Legacy control systems (like TESSELATOR) where such keyboard modules serve as part of master control systems.

          • Maintenance, retrofit or spare parts supply for industrial automation systems to ensure continuous operation of operator interfaces.

          5. Usage Notes & Precautions

           

          • Before installation, verify that the module’s physical dimensions, panel cut‑out size and rear connection style match the existing system.

          • Confirm compatibility of the module with the control system’s architecture (cabinet model, system series, interface type).

          • Since the model is somewhat legacy, confirm key‑layout, key functionality, indicator lights (if any) and compatibility with user interface needs.

          • In panel installation environments, ensure the cabinet has good ventilation, proper grounding and minimal vibration or electromagnetic interference.

          • When using as a replacement spare, confirm the module matches the original in version, function and interface to avoid operational mismatches.

          • For modules kept as spares, periodically verify keyboard operation, key sensitivity and module physical condition to avoid failure when needed.

          • Although this is a keyboard module, standard safety procedures still apply: during maintenance or installation, disconnect control power, follow ESD precautions, and avoid unintended system inputs.
