Verified Technical Data

System Fit and Applications

The module connects four binary field sensors to an AS-Interface network in conveying, material handling, packaging and machine-automation installations. Its compact K45 housing and M12 connections support decentralized installation where IP67 protection is required.

Application Boundaries

This is a four-input standard slave with no digital outputs. It should not be substituted with an A/B slave, M8 connector version, output module or another pin assignment without checking the AS-i master, profile and field wiring.

Compatibility and Procurement Checks

• Match the complete order number 3RK1200-0CQ20-0AA3.
• Confirm four M12 digital inputs and no digital outputs are required.
• Verify AS-i Specification 2.0 compatibility and slave profile 0.0.F.
• Check the 200 mA total sensor-supply limit and two-/three-wire sensor wiring.
• Order the correct 3RK1901-2EA00 or 3RK1901-2DA00 mounting plate separately.
