Operating temperature: -25°C to +60°C
Storage temperature: -40°C to +85°C
Relative humidity: 5–95% (non-condensing)
Protection class: IP20 (suitable for control cabinets, preventing solid particle intrusion and direct water splashing)
Compliance: Meets EU directives 2014/30/EU (EMC) and 2014/35/EU (LVD); exempt from EU Directive 2011/65/EU (RoHS) per Article 2(4) (for industrial control components); electromagnetic immunity compliant with industrial-grade IEC 61000-6-2 standards.
Key Notes for Installation and Use
Mounting: Designed for rack mounting within ABB S100 I/O enclosures. Follow ABB’s S100 I/O Installation Manual for proper alignment, grounding, and wiring—critical for maintaining signal integrity and preventing electrical noise interference (common in industrial environments).
Field Wiring: Ensure connected devices operate at 48 VDC and do not exceed the board’s input current limits (refer to ABB’s technical datasheet for exact limits). Use shielded cables for long runs to minimize electromagnetic interference (EMI).
Regulatory Documentation: Retain ABB’s EU Declaration of Conformity (3BSE088609) for regulatory audits, as the product is RoHS-exempt.
End-of-Life Disposal: Dispose of the unit in compliance with local WEEE regulations (Category 5) to minimize environmental impact.

Strong Anti-Interference & Isolation Performance
Adopts optical isolation technology between input circuits and the main control unit, effectively blocking ground loops and electrical noise from industrial sites.
Complies with industrial-grade electrostatic discharge (ESD) protection standards, with ±8 kV contact discharge and ±15 kV air discharge resistance, avoiding component damage during installation and maintenance.
Meets IEC 61000-6-2 electromagnetic compatibility (EMC) standards, resisting interference from frequency converters, high-voltage motors, and other on-site equipment—ensuring accurate signal reading without false triggers
Compact Design & Easy Installation
Features a slim profile with dimensions optimized for dense rack layouts (typical: ~220mm length × 20mm height × 230mm width), fitting into narrow control cabinet spaces.
Supports tool-less mounting on 35mm DIN rails, enabling quick installation and module replacement, reducing on-site construction time and labor costs.
Lightweight design (0.38kg) minimizes load on rack structures, suitable for multi-module stacking scenarios in large-scale control systems.
