Safety certifications: UL (US Canada), ATEX (Explosion proof), CE (Low Voltage/EMC/ATEX Directive), RoHS compliance

System configuration and upgrade requirements

configuration scheme

Pure compact chassis configuration: only using Compact 200 Series chassis

Mixed configuration: Compact mixed with standard 200 Series baseboard (supports compact in front/back)

Maximum scale: Up to 32 FBMs per single bottom chain, 4 bottom chains supported per FCP280

Upgrade requirements

Space requirement: The installation location should have sufficient horizontal DIN rails

Power Requirements: Supports FPS480-24/FPS400-24/FPS220-24/FPS120-24 power supplies

Cooling requirement: 1 fan tray is required for every 2 adjacent compact baseboards (1 for each baseboard when deployed separately)

Cable replacement: The terminal cable of the standard 200 Series FBMs needs to be replaced with a Compact series adapter cable

Electrical and safety regulations

Grounding requirements: comply with IEC 61000-5-1/5-2 standard (or regional equivalent standard)

Power configuration: 24V DC power supply, supports single/redundant power distribution, triggers icon color change, system alarm, and print notification in case of power failure

Isolation level: FBMs support channel isolation, differential isolation, and group isolation, with some terminal components (TA) providing additional channel isolation

Wiring characteristics: FBMs are hot swappable and do not affect external field device wiring and internal cable connections

Key questions and answers

Question 1: What are the core advantages of the Compact 200 Series I/O subsystem? What scenarios are applicable?

Answer: The core advantages are concentrated in three points: ① High reliability and availability, achieved through ASIC integrated design with high availability of single module 0.999974 and redundant module 0.9999964, suitable for continuous operation requirements; ② Flexible deployment and compact design, with a volume only half of the standard 200 Series, supporting distributed DIN rail/rack installation, reducing wiring costs; ③ Strong environmental adaptability and compatibility, Class G3 pollution protection, 60 ℃ high temperature tolerance, and compatibility with existing 100/200 Series I/O devices, supporting seamless system upgrades. Applicable scenarios include: continuous/batch/discrete control tasks in industrial sites, harsh polluted environments (such as chemical and metallurgical industries), large factories that require remote distributed deployment, and existing I/A Series ®  System upgrade project.
