Interface converter RS422/485 <> RS232
Description
Features
The tecsis interface model EZE20X100001 permits bi-directional connection of RS232 devices with components, which are equipped with an RS422 or RS485 port.
Conversion from RS-232 to RS-422/485 up to 115 K-baud RS485 automatic mode 2 and 4 wire compatible 2 LED for power supply and data traffic No re-configuration of transmission parameters required Min. 1 kV electrical isolation With integrated overvoltage protection Phoenix-case for direct installation on the C-bar Top hat rail housing acc. to DIN EN 50022-35 Supply voltage range up to 24V
The interfaces convert one data line and one handshaking line in each direction and provide electrical isolation between the RS232 side and the RS422/RS485 side. The interfaces are built in a small plastic housing designed for top hat rail mounting according to DIN EN 50022-35. Both interfaces use a build-in switching regulator for power supply and have a wide input voltage range from 12V to 24V. The operating voltage can be supplied by the enclosed AC adaptor or by any other AC or DC voltage in the permissible range. The interfaces have a build-in reverse voltage protection. The power can be supplied by screwed contacts.
Applications Universal Fail-safe interface-converter for applications for top hat rail mounting
industrial
The interface includes two LEDs, with green for indicating the correct supply voltage and red for verifying data transmission in both directions.

Setting the operating modes To configure the RS485 / RS422 Interfaces, the enclosure must be opened to set the mode type/termination DIL switches on the interface module. For this purpose we recommend threading a SUB-D connector with connector body onto the Interface and use the threaded-on connector to assist in removing the housing cover from the housing body.
Termination For all RS485 operating modes it is essential that the bus system be terminated with a termination network which assures a defined rest state in the high-impedance phases of bus operation. The bus system can be connected to a termination network by closing switches #6 and #7 on the interface module.
