tM-7520A
Tiny Isolated RS-232 to RS-422/485 Converter. Supports operating temperatures from -25°C ~ +75°C. Replacement for tM-7520U.
Features
Introduction
Most industrial computer systems provide standard RS-232 serial ports. Though widely accepted, RS-232 has limited transmission speed, range, and networking capabilities. The RS-485 standards overcome these limitations by using differential voltage lines for data and control signals, which transparently converts RS-232 signals into isolated RS-485 signal with no need to change any hardware or software. The tM-7520A lets you easily build an industrial grade, long-distance communication system using standard PC hardware.
The sampling rate of ET-2217H is 8 KHz for all channels, and it utilizes TCP streaming continuous transmission mode to record voltage and current values. The module also provides EMS (EFT/ESD/Surge) protection and 3000 VDC I/O isolation to enhance noise protection capabilities in industrial environments.
Features
- Automatic RS-485 Direction Control
- ESD Protection for the RS-232/422/485 Data Line
- Transmission Speed of up to 115200 bps
