To convert an RS232 signal to two RS485 signals or duplicate an RS485 signal. Possible assemblies: RS232 to Rs485 (1) and RS485 (2) or RS485 (1) towards Rs485 (2) and RS485 (3). Assembly in Casacade possible, for example with two devices, this would give 1 input RS485 to 3 RS485 outputs: first RS485 device to RS485 (1)+ second device, itself leaving in RS 485 (2) and RS485 (3). Protection against overhangs up to 600W, ESD protection +/- 15KV. Degree of insulation: 2500vrms 500DC non-stop. 5 activity diodes: food (PWR), sending (TD), reception (RD), error (E1 and E2). Communication distance 0 to 5km (variable speed from 115200bps to 300bps. Entrance RS232 or RS485: GND / GND / GND / 485 - / 485 + / GND / RXD / TXD / VCC (9-40V) / PGND. RS485 output: TR1+ / TR1- / NC / NC / TR2+ / TR2- / NC.
