GENERAL DESCRIPTION
TD10x-EX-485 input isolation safety barrier, It can supply
isolated DC power of the transmitters from the security zone to the
danger zone, transform the RS-4 85 digital signal of danger zone
into isolated RS-485 or RS-232 digital signal transmission to the
security zone, while increasing the anti-jamming capability of the
industrial production process control system, to ensure system
stability and reliability. It meets IEC/EN61326 standards.
One independent power supply is required. Moreover, within
the product power supply, input and output are mutually isolated.
