Using this device you can eliminate internal I/O-cards for PC. This device also reduces the amount of wiring when connected with 2-wire RS-485 bus. Serial communication settings are made either using handheld programmer or MekuWin PCsoftware. Transmission of fast switching data is limited mainly by the baud rate and the application software. To transmit analog information you can use the transmitter 7100. Serial data converter RS485 / RS232, USB (DCS770, DCS771) WinX Promolog Four I/O-lines Input: Sw itch or NPN/PNP-transistor Removable terminals 1.5 mm² Mounting rail (35 mm) DIN 46277
