SRS-2/4-Z45 Converter Module

Brand: SIMEX sp. z o.o.
The SRS-2/4-Z45 converter module is designed to interconnect MASTER devices equipped with RS-232 to RS-485 bus.

The module can work either with devices controlling direction of transmission - via RTS line, or devices not controlling the direction - control is then fully automatic.

The MASTER functions can be realized by any device, e.g. PC computer with dedicated software.

Connection of more than one MASTER device to the RS-485 bus is prohibited.

The SRS-2/4-Z45 unit guarantees full galvanic isolation between RS-232 and RS-485 circuits.

Only one device SRS-2/4-Z45 type can be connected to RS-485 line.

The converter can work with any devices equipped with RS-485 interface, especially made by SIMEX.

The main purpose of SRS-2/4-Z45 converter is connection of PC host computer with industrial data acquisition and visualization systems based on RS-485 interface.
