Most industrial computer systems provide standard USB ports with limited transmission speed, range, and networking capabilities. The RS-485 standards overcome these limitations by using differential voltage lines for data and control signals. The ICP DAS tM-7561 transparently converts USB signals into isolated RS-485 signal with no need to change any hardware or software. This allows user to easily build an industrial grade, long-distance communication system using standard PC hardware. The module provides 2500 VDC of optical isolation allowing you to separate and protect critical segments of the system from the rest of the RS-485 network.

The ICP DAS tM-7561 is a cost-effective USB to RS-485 converter. Connecting the tM-7561 to a PC, the user get one RS-485 port that allows the user to access RS-485 devices through the USB interface. Like the I-7520, the tM-7561 contains “Self-Tuner” chip auto-tunes the baud rate and data format to the RS-485 network. The ICP DAS tM-7561 module derives its power from the USB port and doesn’t need external power adapter.
