With a compact size of only 20 x 4.6 x 23mm, it can be integrated into various embedded devices for RS485 communication interface expansion. It is suitable for applications such as RS485 sensor data acquisition and Modbus bus node communication. Features SP485EEN-L/TR (RS485 transceiver) 2x RS485 interface expansion (parallel), allowing simultaneous connection of two devices Red power indicator PWR485 interface supports 9-24V input power supply, with internal DC-DC step-down to 5V to power the module and main control device Actual test data for baud rate: Stable communication baud rate: 9600bps/115200bps Maximum communication baud rate tested: 128000bps Multiple forms: Supports various application forms (SMT, DIP, flying leads) Equipped with high-temperature plastic armor, supports SMT reflow soldering temperature (230°C) Includes 1 x Stamp PWR485 1 x HT3.96-4P female socket 2 x HY2.0-4P female sockets (blue + white) 1 x L-shaped hex key 1.5mm (compatible with M2 screws) Applications RS485 communication Modbus device communication Specifications Specification Parameter RS485 Transceiver SP485EEN-L/TR Input Voltage PWR485 interface supports 9 ~ 24V input power / TTL side input voltage 5V Recommended Baud Rate 9600bps / 115200bps Operating Current DC [email protected] [email protected] [email protected] Input Logic Level 3.3V Product Size 20.0 x 4.6 x 23.0mm Product Weight 5.1g Package Size 138.0 x 93.0 x 10.0mm Gross Weight 7.3g Learn and Documents → DOCUMENTS Show more
