Brief description

The RS232-MPI adapter can realize the level switch from RS232 to RS485 port and the switch of protocols from RS232 to MPI MultiPoint interface. it is used for the communication between S7-300 PLC and the third party HMI, such as touch screens Weinview, Kinco, MGGS, Samkoon which support MPI protocol.

It is the optical isolation adapter that aims to industrial designs. Provided with surging protection and lightening-proof circuit both at RS232 and RS485 ports and being able to be inserted and extracted with power on randomly, it is especially suitable for industrial fields where there's much interference to easily destroy the communication ports as its various protections secure the safe running of the system.

Characteristics and main technique parameters

·         24V DC powered by MPI port of PLC, appox. 1w power consumption with over current protection and surge protection.

·         1000V DC isolation voltage, 10~70°C working temperature

·         RS232 interface has surge protection, RS485 interface has 500W lightning-defend protection and over current protection

·         RS232 interface baud rate 9600bps, 19.2Kbps, 38.4Kbps standard baud rate self-adaption

·         MPI interface baud rate 187.5Kbps and 19.2Kbps self-adaption no need for any other devices

·         Power indicator, RS232 indicator and MPI indicator, the cable length is 3.5m total

·         Different HMI should use different cables, pls check with the suppliers.
