The 1300 m bus length allows large plant layouts. Recommended for system integrators who value robustness and simplicity.
Manager’s Insight
From a cost-benefit perspective, the TSXSCY21601 delivers stable communication for up to 28 nodes. The master/slave architecture works well with existing Modbus networks. We have seen excellent performance in water treatment and conveyor systems. It is a cost-effective upgrade for legacy Premium installations.
Applications & Suitable Devices
- Ideal for: PLC networks, remote I/O, drives, and sensors
- Industries: Manufacturing, water/wastewater, energy, material handling
- Use with: Modicon Premium CPUs, Atrium controllers, third-party Modbus devices
- Typical applications: Data acquisition, process control, SCADA integration
Frequently Asked Questions
- Can I use this module with other PLC brands?
It is designed for Modicon Premium. It can communicate with any Modbus RTU device as a master or slave. - What is the maximum cable length?
1300 m for the main bus. Tap links are limited to 15 m. - Is the RS485 port isolated?
Yes, it provides galvanic isolation to protect against ground loops. - Can I use ASCII mode?
Yes, the module supports both RTU and ASCII transmission frames. - How many devices can I connect?
Up to 28 devices, with address range 0–97. - Is Unity Pro mandatory?
Yes, configuration and diagnostics require Unity Pro software. - What is the typical current draw?
350 mA at 5 V DC, ensure your power supply supports it.
Selection Guide
- If you need a cost-effective RS485 master for Premium, choose this module.
- For high node counts (up to 28), this module fits perfectly.
- When long distance is required (1300 m), this is the right option.
- If you already use Unity Pro, integration is seamless.
- For legacy systems with PCMCIA expansion, this is the direct replacement.
