Overview

Core Product Advantages (Extracted from 3BSE043446R501 Official Specs)

1. Robust Industrial Mechanical & Environmental Protection

• Front panel IP66 / NEMA 4X indoor sealed design, rear housing IP20 protection; powder-coated aluminum back casing with outstanding chemical resistance against weak acid, salt water, diesel, edible oil and cleaning agents

• 640×480 64K color TFT touchscreen with Autotex F157/F207 overlay, withstands 1,000,000 touch operations; screen surface resists acetone, isopropanol and toluene long-term erosion

• Mounting cutout dimension 188.5×137.5mm, compatible with cabinet plate thickness 1.5–9.0mm; vertical mounting ambient temperature range 0~50°C, horizontal installation 0~40°C, storage temperature -20~70°C, 5–85% non-condensing humidity.

• Overall weight only 1.2kg, mounting depth 56mm (156mm with heat dissipation clearance), compact structure for standard industrial control cabinets

1. Multi-Channel Isolated Communication Architecture

• Integrated rich native ports: Shielded RJ45 Ethernet (with galvanic DC/DC isolation, anti-ground loop interference), 25Pin RS422/485 D-sub, 9Pin RS232 serial, USB1.1 Host/Device dual interfaces, Type I/II Compact Flash internal expansion slot

• Supports optional CB801 Profibus DP expansion module (87×70×30mm, 0.1kg weight) for fieldbus distributed control; CB810 USB-to-Ethernet adapter available for offline project download via PC crossover cable

• Ethernet port features independent galvanic isolation separate from the 24VDC power supply; RS232/RS485/USB share a common internal ground; an external isolation module is recommended for multi-device networking to eliminate communication glitches caused by ground potential differences.

• RS485 bus built-in 120Ω terminal resistance with fail-safe circuit design; standardized bus wiring specification, shielded twisted pair cable with single-end grounding or 0.1μF capacitor floating grounding for long-distance transmission

1. Complete System Debug & Recovery Function via DIP Mode Switches

2. Four rear-mounted DIP mode switches support multi-operation modes without software intervention:

• 0000 Run Mode: Standard factory production operation state

• 0010 System Restore: Reset file system & registry, revert to factory original firmware version, and recover from fault states.

• 0100 Image Load Mode: Full system firmware batch upgrade, overwrite all local project files, and recover from firmware faults.

• 1000 Service Menu: One-click IP address modification, touch screen calibration, project data erasure

• 1110 Self-test Mode: Hardware self-inspection for display, communication, and storage modules

• Hardware hard reset function via switch No.4 for unbootable fault recovery.

1. Expandable Storage & Stable Power Supply Design

• Built-in 12MB native flash memory for project, font and alarm recipe storage; internal CF card slot supports SiliconSystems/SanDisk industrial CF I/II cards for memory expansion

• Standard 20–30VDC 24V SELV power input, rated current 0.4A, peak max 0.9A; internal 3.15AT 5×20mm DC fuse for overcurrent protection

• CR2450 lithium RTC battery (Sanyo/Panasonic UL certified) with minimum 3-year service life; real-time clock precision ±20PPM, monthly maximum time deviation ≤1 minute at 25°C ambient temperature

1. Strict Global Safety & Hazardous Area Compliance

• UL 1604 Class I Division 2 Groups A/B/C/D explosion-proof certification: Strict operation rules for hazardous zones – power cut before disconnecting modules, no random component replacement to maintain explosion-proof performance

• CE EMC compliance: EN61000-6-4 emission standard & EN61000-6-2 industrial immunity standard, DNV marine industry certification available

• Low Voltage Directive 72/23/EEC & EMC Directive 89/336/EEC certified, meets IEC 60950 safety standard for industrial control equipment.
