UST21 Schneider Relay Module
UST21 is a high-performance controller launched by SCHLEICHER
brand, widely used in industrial automation control systems,
especially suitable for scenarios that require high-precision
measurement and positioning, such as precision positioning control
on automated production lines, position control and motion control
of robot systems, and elevator door control systems. This product
adopts a 24V DC input voltage, with a maximum load current of 4A.
It supports RS485 communication interface and can operate stably
within a working temperature range of -20 ° C to+60 ° C. The
protection level is IP20. Its compact design and high reliability
make it an ideal choice in the field of industrial automation. Some
versions also support eight channel analog input
(thermocouple/voltage/current), which can be set by software for
sensor types and module parameters. It supports multiple standard
thermocouples and has a wide voltage range input (18-36V DC), low
power consumption, RS-485 network connection (supporting Modbus
RTU/ASCII protocol), built-in watchdog, 3000V electrical isolation
and other functions, ensuring stable and reliable operation. At the
same time, it is easy to install and supports standard rail card or
screw fixation.
