RS232 to RS485 Adapter Module Industrial 3.3V/5V

RS232 to RS485 Adapter Module Industrial 3.3V/5V Description

Specification: Origin: Mainland China Type: Module Description: RS232 to 485 module description RS232 to 485 module can realize the mutual conversion between RS232 and 485 communication systems: the module has automatic flow control function, realizes automatic conversion of RS485 transmission and reception. The module is designed with special consideration of signal integrity and EMC characteristics, and multiple protection measures are added, so it can be used in various industrial applications. The module is simple in design, beautiful in appearance, stable and reliable. Working voltage: 3.3V or 5.0V (should not exceed +/-5% of the nominal voltage) Working current: 5mA Working temperature: -30-70 Communication rate: 300-120000 (120K) bps, transparent transmission Module size: PCB size 28*50*10mm (length*width*height): with terminal size 2865*13mm (length*width*height) Screw hole size: screw hole center distance 22*42mm Interface description: V+ and V-: positive and negative poles of the power input interface. RX and TX: RS232 bus receiving and sending, need to cross when connected with other RS232 modules, that is, RX is connected to TX. A and B: DATA+ (A) and DATA- (B) of RS485 bus. GND: RS485 reference ground, same as V-, generally can be left unconnected. Product size: 68.00x28.00x12.00mm Product size: 2.68x1.1x0.47inch Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement. Included: 1 x Industrial RS232 to RS485 Module
