NEW 6ES7138-4HA00-0AB0

Model and Series Identification: This product, designated 6ES7138-4HA00-0AB0, is part of the SIMATIC ET 200S distributed I/O system, classified as a “Counter Module 2xHS” (2-channel high-speed counter). It is engineered to capture and process high-frequency digital signals from encoders, pulse generators, or other counting devices, enabling accurate position, speed, or event counting in industrial processes.

Core Functionality: Its primary role is to perform high-speed counting operations on digital input signals, supporting various counting modes to meet diverse application requirements. It can measure pulse frequencies, count events, track positions via incremental encoders, and generate output signals based on predefined count values, making it suitable for motion control, packaging machinery, material handling, and quality inspection systems.

Counting Specifications: The module features 2 independent high-speed counting channels, each capable of handling input frequencies up to 100kHz, ensuring precision even for fast-moving processes. It supports multiple counting modes, including:

Electrical Characteristics: It operates on a 24V DC power supply (19.2-28.8V DC) with reverse polarity protection to prevent damage from wiring errors. The input circuits are optically isolated from the backplane bus, providing immunity to electrical noise in industrial environments. Each counting channel draws a maximum current of 7mA at 24V DC, ensuring efficient power usage.

Mechanical and Integration Features: Designed for the ET 200S modular system, it mounts on a standard 35mm DIN rail and connects to the system’s backplane bus via a terminal block. The module has a compact width of 25mm, optimizing space in control cabinets. It features LED indicators for power, module status, and channel activity, simplifying diagnostics and troubleshooting.

Configuration and Compatibility: Configurable via Siemens’ STEP 7 or TIA Portal software, it integrates seamlessly with ET 200S stations and SIMATIC controllers (e.g., S7-300, S7-400, S7-1200/1500) through the PROFIBUS or PROFINET network. It supports data exchange with the controller via process data objects (PDOs), enabling real-time monitoring and control of counting operations.

Environmental and Compliance Standards: The module operates in a temperature range of -25°C to 60°C (storage: -40°C to 70°C) and is resistant to vibration and shock, meeting industrial durability standards. It complies with international regulations such as IEC 61131-2 and RoHS, ensuring compatibility with global industrial requirements and environmental safety.
