Active AS-i Modules in South Africa - Price, Stock & Availability at Communica

Overview of Active AS-i Modules

Active AS-Interface (AS-i) modules are widely used in South African automation, manufacturing, and process control for simplifed field device connectivity. These modules allow for easy integration of IO devices on the AS-Interface network - providing digital or analog expansion, device status feedback, and machine safety features. Communica stocks a diverse range from leading brands, supporting both compact field modules and panel-mount types.

What Is AS-Interface (AS-i)?

AS-i, or Actuator-Sensor Interface, is an open, cost-effective network protocol enabling connection of sensors, actuators, and control devices via a simple two-wire cable. It is popular in process plants, packaging, food & beverage, and material handling industries across South Africa for its:

• Easy wiring with unshielded flat cable
• Quick device add/remove for scalable automation projects
• Robust operation and broad industry adoption

How to Select an AS-i Module for Your Application

To achieve reliable fieldbus integration and value for your spend, consider the following selection steps:

1. List IO requirements: Count your sensors and actuators, and decide on digital vs. analog channels.
2. Match form factor: Choose between rugged IP67 block modules (for field) or IP20/DIN modules (for control panels).
3. Confirm voltage and current specs: Check your site's AS-i master supply (usually 24VDC in South Africa industrial use) and device draw.
4. Review compatibility: Use models compatible with your network master and field devices.
5. Consider brand preference: If standardising, Communica supplies matching connection and expansion accessories for key brands.

Example: Price Breakdown (South African Scenario)

Suppose your automotive automation project in Gauteng needs 8 channels of digital IO. At current rates, a Pepperl+Fuchs 8DI/8DO AS-i block module might cost approximately R2,500 VAT incl. Similar models from Turck or IFM are also stocked; always check stock status and request a VAT invoice or quote for bulk/education use.
