Description:

Electronic device for converting a serial communication line from the RS232C to the RS485 (Half duplex) standard with automatic handling of the data flow or from the RS232C and RS422 (Full duplex) standard.

This device allows for connecting equipment with an RS232C serial line to components equipped with an RS485 or RS422 serial interface. This extends the typical 15-m transmission distance of the RS232 standard .

Technical specifications:

POWER SUPPLY: 24/115/230 Vac ± 10% 50/60Hz. Power consumption <70mA; 1.8 VA max.

SIDE RS232C: Standard EIA RS232 C / CCITT V28. ESD +/-8kV Surge protection. Maximum transmission distance 15m.

SIDE RS485/422: Standard EIA RS485 / EIA RS422 /CCITT V11 Surge protection provided by surge suppressor. Galvanic isolation by means of optical isolators. Maximum transmission distance: 1200 m. Maximum number of devices that can be connected: 32.

GENERAL: Weight 240 g. Dimensions 4M DIN 43880 (mm 71x90x58). DIN EN 50022 mount. Working temperature from 0 to 60 șC. Storage temperature from -20 to 80 șC. Maximum tested transmission speed: 115 kBaud. EC labelling compliant .

The device can operate at different voltages depending on particular needs (values +/-10%):

110 Vac: Apply voltage between terminals [1] and [2].

230 Vac: Apply voltage between terminals [1] and [3].

24 Vac: On request.

The device can be connected in one of two ways: by using the 9PinF connector located on the front panel, or by using the terminal block.
