6AG1350-2AH01-4AE0
Product Profile
6AG1350-2AH01-4AE0 is a SIPLUS S7-300 FM 350-2 Counter Module from Siemens, based on the standard 6ES7350-2AH01-0AE0 with conformal coating for enhanced environmental protection. It is an intelligent 8-channel counter module designed for universal counting and measurement tasks in demanding industrial environments.
The module operates with a supply voltage of 24 V DC and supports a maximum counting frequency of 20 kHz. It features 8 digital inputs and 8 digital outputs, and supports multiple encoder types including 24 V incremental encoders, direction encoders, initiators, and NAMUR sensors.
The SIPLUS version is approved for an extended temperature range of 0°C to +60°C and is resistant to condensation, chemically active substances (Class 3C4), and biologically active substances (Class 3B2) in accordance with EN 60721-3-3. The product is currently commercialized and available as a standard product.

System Role
The 6AG1350-2AH01-4AE0 functions as an intelligent 8-channel counter module for the SIMATIC S7-300 and ET 200M systems. It performs high-speed counting and measurement tasks independently, offloading the CPU from time-critical pulse processing.
The module supports 7 operating modes, including continuous counting, single counting, periodic counting, frequency measurement, speed measurement, cycle duration measurement, and dosing. Except for dosing mode, all channels can operate independently in any mode.
The FM 350-2 provides hardware interrupts and diagnostic alarms for rapid response to process events. It includes a red SF (group error) LED for fault indication. The module is configurable via STEP 7 with the included configuration package, which provides parameter assignment screens and standard function blocks (FC 2, FC 3, FC 4, FC 5) for data exchange with the CPU.
