XSA-RS485 communication barrier
· RS485 signal, intrinsically safe input. The RS485 signal is converted to an isolated RS485 (or RS232) signal. Terminal supply or DIN rail power supply is available.
· The XSA-RS485 communication barrier is used to convert the RS485 signal to the hazardous area of the field into an RS485 (or RS232) signal for transmission to the safe area to realize two-way communication between the dangerous area and the safe area. The product requires independent power supply and is isolated between the power supply-input-output.
· Hazardous area signal: RS485 digital signal.
· Safety zone signal: RS485 digital signal (or RS232 digital signal).
· Signal transmission rate: ≤ 56kbps. Transmission delay: ≤10uS.
· Small plug-in structure with 35mm DIN standard rail card mounting. Screw terminal, the wiring is fastened by M3 screw.
