Communica supplies AS-Interface (AS-i) user modules suitable for machine automation, process control, and industrial IO applications used by South African integrators, OEMs, and educational labs. AS-Interface is a fieldbus system designed to connect binary devices-such as sensors and actuators-to controllers with minimal wiring, fast installation, and high reliability.

Why Choose AS-Interface User Modules?

  • Rapid device integration on the AS-i bus for digital IO, analog IO, or mixed modules
  • Simple 2-wire redundant cabling for power and data reduces costs and drives up reliability
  • Wide compatibility with PLCs and automation brands like ABB and Siemens
  • Decentralised installation-mount modules directly on machinery or in cabinets
AS-Interface modules are key for scalable distributed field IO, with rapid expansion and simplified troubleshooting-ideal for panel builders and system upgraders across South Africa.

Available AS-i User Module Options

Type Channels Mounting IP Rating Popular Brands
Digital Input 2/4/8 DIN, Field IP20/65/67 ABB, TURCK
Digital Output 2/4/8 DIN, Field IP20/67 Pepperl+Fuchs
Mixed IO 4 DI / 4 DO Field, Panel IP65/67 Siemens
Analog IO 2 AI / 2 AO Panel IP20 TURCK
Modules are specified for process and discrete control environments-confirming input voltage (e.g., 24V DC typical), channel type, and enclosure IP rating is recommended for new system builds or field upgrades.

Key Specifications

  • Input/Output: digital, analog, or combination
  • AS-i profile (e.g., standard or safety modules)
  • Mounting style: DIN-rail, panel, or field install
  • IP rating for local or harsh conditions
  • Integrated diagnostics for easy troubleshooting
When quoting, Communica can provide datasheets for stocked brands and offer compatibility guidance with leading PLCs and automation systems.
