Schneider Electric TSXCTZ1A Counter Module

TSXCTZ1A Modicon TSX Micro Single-Channel Counter Module

Product Introduction

The Schneider Electric TSXCTZ1A counter module adds high-speed counting capabilities to the Modicon TSX Micro automation platform. This module features one counting input, supporting resistive 24 V DC sensors and 2-wire or 3-wire proximity sensors. It is ideal for applications requiring pulse counting, position monitoring, or frequency measurement.

Specifically, the TSXCTZ1A operates at counting frequencies up to 40 Hz and network frequencies up to 100 Hz. The input accepts both 5 V DC and 24 V DC voltage levels, providing flexibility for various sensor types. With a response time of 1.5 ms for event processing and 8 ms for the master task, this module ensures timely counting updates for your control application.

The module's positive logic input configuration simplifies integration with standard industrial sensors. Although not a Green Premium product, the TSXCTZ1A remains a valuable option for maintaining and expanding existing TSX Micro installations that rely on counting functions.

Input Specifications and Performance

The TSXCTZ1A offers clear input characteristics for dependable counting. For 24 V DC inputs, the state 1 threshold is ≥11 V, while state 0 is ≤5 V. For 5 V DC inputs, state 1 is ≥2.4 V and state 0 is ≤1.2 V. These well-defined thresholds ensure reliable signal detection even with moderate noise.

Current consumption for the TSXCTZ1A is only 15 mA, making it a low-power addition to the TSX Micro system. Input impedance is 1.4 kΩ for 24 V DC and 0.27 kΩ for 5 V DC at rated voltage. For 5 V DC at 2.4 V, impedance is ≥0.44 kΩ. These values provide adequate loading for most industrial sensors.

The module includes a sensor power supply of 2.5 V, supporting 2-wire and 3-wire proximity sensors. The input type is resistive 24 V DC, complying with IEC 1131 Type 2 standards. This compliance ensures compatibility with widely available industrial sensors.

Response Time and Counting Capabilities

The TSXCTZ1A processes counting events with a response time of 1.5 ms. This fast event processing ensures accurate counting even at the maximum frequency of 40 Hz. The master task response time is 8 ms, providing periodic updates to the controller for monitoring and control purposes.

Counting frequency of 40 Hz handles most standard counting applications, such as conveyor position monitoring, part counting, and rotational speed measurement. The network frequency of 100 Hz supports higher-speed signal processing for more demanding applications.

For 24 V DC inputs, the guaranteed current at state 0 is ≤2 mA, and state 1 is ≥6 mA. For 5 V DC inputs, state 0 current is ≤1 mA, and state 1 is ≥3.7 mA. These values ensure reliable switching with a wide range of sensors and switches.

Installation and Compatibility

The TSXCTZ1A is designed specifically for the Modicon TSX Micro automation platform. It mounts directly onto the TSX Micro backplane, using the same mounting hardware as other TSX Micro modules. Installation is straightforward and requires no special tools or complex configuration.

Before installing the TSXCTZ1A, verify that your power supply can handle the additional 15 mA load. Plan your wiring carefully to maintain signal integrity and minimize electromagnetic interference. Use shielded cables for the counting input if operating in electrically noisy environments.

The module is suitable for both new installations and as a replacement for existing counter modules in legacy systems. Its country of origin should be verified at the time of ordering for regional compliance requirements.

Environmental and Compliance Information

The TSXCTZ1A meets the environmental standards applicable at the time of its production. It complies with IEC 1131 Type 2 standards for 24 V DC inputs, ensuring reliable operation with standard industrial sensors. The module's compact design and low power consumption make it an efficient addition to the TSX Micro system.

This product is not classified as a Green Premium product. It will not be compliant with future environmental regulations, so customers should consider this when planning long-term system expansions. However, for existing installations where environmental certification is not a primary concern, the TSXCTZ1A remains a dependable counting solution.

Wiring diagrams are available in the product documentation to assist with proper installation. For applications requiring the latest environmental compliance, consider newer Modicon platforms and their corresponding counter modules.

Packaging and Logistics

Each TSXCTZ1A module comes in a single-unit package weighing 0.20 kg. The packaging ensures safe transit and easy handling. For larger orders, bulk packaging options may be available upon request.

All shipments go out via trusted global couriers, including FedEx, UPS, and DHL. This ensures your TSXCTZ1A modules arrive quickly and safely to support your maintenance or expansion projects. The product carries an 18-month warranty from Schneider Electric.
