The ST-5221 module from GE Fanuc Emerson is integral to the RSTi PacSystem and acts as a serial communications device. Operating on an RS-422 serial channel, this module can handle a wide baud rate range from 300 bps to 115,200 bps. Designed for efficiency, it features one communication channel that facilitates simultaneous data transmission in both directions, adhering to protocols such as full duplex and ASCII.
The ST-5221's physical dimensions measure 99 mm in length, 12 mm in width, and 70 mm in height, enabling it to fit into compact setups. Data management is efficient, with an I/O data size of 6 bytes for both input and output. Moreover, the module includes substantial buffers: a receive buffer of 1024 bytes and a transmit buffer of 256 bytes, allowing for smooth communication with compatible devices like scales, printers, and barcode readers.
Connection is straightforward with a spring clamp terminal block, simplifying installation and wiring processes. The module utilizes a maximum of 155 mA from a 5V DC power source in terms of power consumption.
