50010R-10

Overview

The Model 50010R-10 is a TPT/XF twisted pair transceiver module manufactured by Echelon Corporation. It provides a transformer-isolated differential Manchester encoded communication interface for LONWORKS networks, operating at a bit rate of 78 kbps. The device requires a +5VDC power source and connects to Neuron Chip-based control systems via dedicated connectors. It supports network bus lengths up to 1400 meters and includes polarity-insensitive wiring capabilities.

Feature Summary

• Transformer isolation between the network bus and I/O lines ensures common mode rejection and reduces susceptibility to ground loops in electrically noisy environments.
• Differential Manchester encoding allows for polarity-insensitive network wiring, simplifying installation and reducing configuration errors.
• Compliant with European Directive 2002/95/EC (RoHS) regarding the restriction of hazardous substances in electrical equipment.

Applications

• LONWORKS control system integration
• Industrial automation networking
• Building automation systems

Procurement Notes

Verify that the specific ordering suffix matches the required transmission speed variant. Confirm RoHS compliance status if mandated by project specifications. Ensure compatibility with the host Neuron Chip architecture before procurement. Review safety agency listings such as UL and CSA for final product integration requirements.

Selection Notes

Select this model specifically for applications requiring a 78 kbps data rate over twisted pair cabling. Verify that the host system utilizes a compatible Neuron Chip and memory configuration. Consider environmental temperature ranges when determining maximum node counts per channel. Ensure the motherboard mounting pattern aligns with the recommended hole grid dimensions.

Part Context

This component belongs to the TPT/XF series of twisted pair transceivers designed for LONWORKS networks. It is functionally paired with the 50010-10 model, differing primarily in regulatory compliance certifications. The series enables cost-effective deployment of LonTalk protocol nodes without custom transceiver design.

Replacement Considerations

The Model 50010-10 serves as a functional substitute within the same series, offering identical electrical performance but lacking the specific RoHS certification found in the 50010R-10 variant. Both models share the same physical footprint and mounting requirements.

FAQ

What is the maximum network bus length supported by the 50010R-10?

The maximum worst-case network bus length is 1400 meters (4600 feet).

How does the transceiver handle polarity in network wiring?

It uses differential Manchester encoding, which makes the network wiring polarity insensitive.

What is the typical supply current consumption?

The typical supply current is 10mA.
