Product Overview

The ABB 3BDH000690R1 CI920AS is a sophisticated communication interface designed for the Advant AC800M distributed control system. This module is specifically built to bridge the gap between high-level control logic and field instrumentation in demanding industrial sectors. With built-in redundancy capabilities, the CI920AS ensures maximum uptime and system availability. Its rugged design makes it suitable for hazardous locations, providing intrinsically safe connectivity without compromising signal speed or reliability.

Core Technical Advantages

Explosion Protection and Hazardous Safety

Safety is a cornerstone of the CI920AS design. It is fully certified for ATEX Zone 1 environments, making it an ideal choice for oil and gas, chemical processing, and mining operations. By utilizing intrinsic safety principles, the module limits electrical and thermal energy to levels that cannot ignite a surrounding explosive atmosphere, ensuring the safety of both personnel and plant assets.

G3 Level Corrosion Resistance

Industrial environments are often filled with airborne contaminants that can degrade sensitive electronics. The 3BDH000690R1 meets the ISA-S71.04 G3 standard for corrosion resistance. This means the module is protected against harsh gases and high humidity (up to 93 percent), allowing for a longer service life and reduced maintenance costs in coastal or chemically intensive locations.

Optimized Form Factor for Cabinet Density

With a width of only 20mm, the CI920AS allows for high-density mounting within automation cabinets. This compact footprint, combined with its lightweight 0.14 kg profile, facilitates easy installation and integration into existing AC800M racks. Despite its small size, it maintains full functional integrity and climatic resilience within a wide temperature spectrum.

Technical FAQs

Q1: What does the ATEX Zone 1 certification imply for installation?

A1: This means the CI920AS can be safely installed in areas where an explosive atmosphere is likely to occur occasionally during normal operation, provided it is part of an intrinsically safe system.

Q2: What is the recommended shipping weight for this module?

A2: While the net weight is 0.14 kg, for international logistics, we suggest a gross shipping weight of approximately 0.35 kg to include protective anti-static padding and industrial-grade boxing.

Q3: How does G3 corrosion resistance benefit the module?

A3: G3 rating protects the internal PCB and components from severe sulfur and chloride levels, preventing trace corrosion that often causes intermittent communication errors in wastewater or industrial plant environments.
