ABB IMCIS22 – Serial Communication Interface Module for Symphony/INFI 90 systems

The ABB IMCIS22 is a communication interface module typically used to bring serial devices—like flow computers, drives, analyzers, bar code readers, weigh feeders, or legacy PLCs—into ABB Symphony/INFI 90 control architectures. From my experience, it’s a practical way to extend an installed base without overhauling field wiring. You might notice that it behaves like a reliable serial gateway inside the rack, speaking Modbus RTU or ASCII on the line side and handing clean data to the controller over the backplane.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days from shipment
• Lead time: 1 week if in stock; no more than 1 month latest
• Payment: 50% advance payment; full payment prior to delivery
• Express options: FedEx, UPS, DHL

Key Features

• Dual serial channels – Typically provides independent serial ports for connecting multiple field devices.
• RS-232/RS-485 support – Commonly configurable per channel, enabling point-to-point (RS-232) or multi-drop (RS-485) wiring.
• Modbus RTU and ASCII – Often used as Modbus Master or Slave; ASCII framing helps with smart instruments or printers.
• Backplane integration – Interfaces with the Symphony/INFI 90 module bus for deterministic data exchange to the controller.
• Isolated ports – Electrical isolation (in many cases) reduces ground loop issues and protects upstream electronics.
• Configurable baud rates – Typical speeds from low baud up to 115.2 kbps, covering most legacy serial devices.
• Rack-friendly form factor – Single-slot plug-in design for standard ABB mounting units; easy to service or replace.

Technical Specifications

Related or Supporting Products

• ABB IMCIS12 – Earlier-generation serial interface; typically fewer configuration options and lower supported baud rates.
• ABB INNIS01 / INNIS21 – Network interface modules for INFI-NET; used when plant networks need bridging or expansion.
• ABB INNPM12 – Network processing module; often paired for higher-level network management in Symphony systems.
• Shielded RS-485 cables and 120 Ω terminators – Recommended for long multi-drop lines to minimize noise and reflections.

One thing I appreciate is how easily the IMCIS22 slots into existing I/O bays. A utilities client used it to consolidate six legacy analyzers over a single RS-485 trunk; downtime was under two hours, mostly wiring and address checks. It seems to be a straightforward path to add field data without touching the main controller program much.

Installation & Maintenance

• Panel/Cabinet – Install in a standard ABB mounting unit within a clean, ventilated cabinet. Keep ambient within the stated temperature range.
• Grounding & shielding – Bond shields at one end (typically the host side). Maintain a solid control ground; avoid ground loops.
• RS-485 wiring – Use twisted pair, 120 Ω terminations at both ends, and bias resistors as required. Keep stubs short to reduce reflections.
• Surge protection – In noisy or outdoor runs, add surge arrestors/isolators at panel entries.
• Configuration – Set baud, parity, addressing, and framing to match field devices. Validate with a serial test tool before going live.
• Routine maintenance – Inspect connectors quarterly, clean dust with dry air, review diagnostic counters. Firmware updates (where applicable) should be aligned with site change control.
• Spares strategy – Keep one spare per critical rack, especially where serial links aggregate multiple instruments.

Quality & Certifications

• CE marking and UL recognition are typically available for ABB Symphony/INFI 90 modules of this class.
• RoHS conformity varies by production period; many later revisions comply. If you need a specific RoHS statement, share the exact hardware revision.
• Manufacturer warranty is commonly 12 months; we provide a 365-day warranty from shipment on supplied units.

Note: Minor variations can exist between IMCIS22 hardware/firmware revisions. If you can provide the part number suffix and firmware level, we’ll align compatibility and configuration details to your installed base.
