TD301D485H-E

Overview

The TD301D485H-E is a single-channel, high-speed RS-485 isolated transceiver module manufactured by Mornsun. It provides galvanic isolation between the data bus and the host interface to protect sensitive electronics from voltage spikes and ground potential differences. The device operates within an industrial temperature range of -40°C to +85°C and utilizes a DIP-10 through-hole package for reliable mounting in various electronic assemblies.

Feature Summary

• Provides electrical isolation between the RS-485 communication bus and the host system to prevent ground loops and protect against transient voltages.
• Supports high-speed data transmission rates suitable for robust industrial communication protocols.
• Designed with a through-hole DIP-10 package configuration for standard PCB integration.

Applications

• Industrial automation systems requiring isolated serial communication links
• Factory floor networks connecting PLCs and remote I/O modules
• Building management systems utilizing RS-485 bus topologies

Procurement Notes

Verify the specific suffix E against official Mornsun documentation to confirm exact pinout and isolation specifications. Ensure compliance with current UL certification status, as previous records indicate potential administrative lapses affecting validity dates. Confirm RoHS compliance directly with the manufacturer or authorized distributor before finalizing procurement orders.

Selection Notes

Select this component when galvanic isolation is mandatory for RS-485 networks in electrically noisy environments. Verify that the DIP-10 form factor aligns with existing board space constraints. Ensure the required data rate and operating temperature range fall within the specified industrial limits for the target application environment.
