PRODUCT DESCRIPTION
3RK7243-2AA30-0XB0 AS-Interface master communication module
Siemens 3RK7243-2AA30-0XB0 is the CM 1243-2 AS-Interface master communication module for SIMATIC S7-1200. It connects a compatible CPU to AS-Interface sensors and actuators for distributed machine-level I/O.
The module implements AS-Interface version 3.0 master profile M4 through one AS-i port. It supports up to 62 slaves with digital I/O capacities of 496 inputs and 496 outputs. The controller backplane supplies module electronics, while the AS-i circuit requires its specified supply arrangement; cycle time depends on the number of connected slaves.
