TC-RS485 communication isolator
· Distribution voltage 9V, 12V. The RS485 signal is converted to an isolated RS485 (or RS232) signal. Terminal supply or DIN rail power supply is available.
· The TC-RS485 communication signal isolator is used to provide an isolated DC power supply to the field instrument and convert the RS485 signal to an isolated RS485 (or RS232) signal for transmission to the control system. This product requires independent power supply, power-input-output isolation.
· Input signal: RS485 digital signal.
· Output signal: RS485 digital signal (or RS232 digital signal).
· Signal transmission rate: ≤ 56kbps. Transmission delay: ≤10uS.
· Card-mounted structure, mounted on a 35mm DIN standard rail card. Screw terminal, the wiring is fastened by M3 screw.
