1. Product Overview

2. Technical Specifications

2.1 Electrical Parameters

• Communication: Proprietary SUNID RS232 serial protocol, optimized for later WEStation mainboard communication definition, backward compatible with partial SUNMD ports for field replacement flexibility.

• Power Supply: 5VDC direct power feed from internal console control circuit, total power consumption below 1W.

• Hardware Configuration: Integrated left/right operation pushbuttons + dedicated embedded drive PCB inside housing; built-in ESD suppression circuit to mitigate EMI interference from nearby cabinet relays and power modules.

2.2 Mechanical & Environmental Parameters

• Enclosure: Black integrated industrial plastic shell for flush panel embedded mounting, same standard cabinet cutout dimension as H01 for direct drop-in interchange installation.

• Dustproof Structure: Reinforced rubber surrounding dust barrier to block control room fine dust into internal rolling mechanical assembly.

• Working Temperature: 0℃ ~ +55℃ (in-control-room operating range); storage range: -40℃ ~ +85℃, applicable humidity 5%~95% RH non-condensing, compliant with industrial CE component standards.

2.3 H02 Version Exclusive Features

1. Black outer casing is the most visible distinction versus H01 white housing.

2. SUNID serial communication instead of H01 SUNMD, customized for third-gen WEStation upgraded system firmware.

3. Optimized internal ball roller structure for smoother cursor positioning and longer continuous service life on 24/7 running DCS console.

4. Fully interchangeable with H01 mechanically without panel modification for emergency site replacement.

3. Core Functions

1. Primary cursor control input replacing standard mouse for selecting pump, valve and other field equipment icons on WDPF process graphic screens.

2. Cooperate with panel membrane keyboard to complete setpoint modification, alarm reset, screen switching and control logic parameter download for DCS daily operation.

3. Standard factory HMI component for retrofitting upgraded WEStation consoles of thermal & nuclear power WDPF distributed control systems.

4. Application & Supply Information
