Overview
The 6ES7194-4CC10-0AA0 is a Siemens SIMATIC DP connection module for the ET 200pro EM 2 Count 24V technology module, carrying two M12 connectors for the counter inputs. It operates at 24 V and is rated for in-cabinet use within the ET 200pro distributed I/O system. The module weighs 372 g and measures 14.1 x 6.8 x 6.5 cm, fitting the ET 200pro form factor for direct mounting on the backplane without additional enclosure space.
Function & operation
This connection module bridges the ET 200pro EM 2 Count 24V electronic module to the field wiring via two M12 circular connectors, providing a sealed interface for high-speed counting applications in harsh environments. The 24 V supply powers both the module and the connected sensor circuits, with the M12 pinout carrying power, signal, and shield in a single connector. The module is part of the EM 2 Count 24V series, designed for two-channel counting. The M12 connectors simplify field wiring and reduce installation time compared to screw-terminal blocks.
Applications
The ET 200pro system is Siemens' distributed I/O platform for applications outside the control cabinet — common on conveyor systems, packaging machines, material handling, and automotive assembly lines. The EM 2 Count 24V connection module supports encoder and pulse counter inputs on these machine sections, feeding position and speed data back to the controller over PROFIBUS or PROFINET.
