- noise immunity in accordance with EN 61000-6-2
- Galvanic isolation with an insulation voltage of min. 1 kV
- Broad supply voltage range of 12 ... 24 V AC / DC
- Housing for top-hat-rail installation
- Shipped optionally with or without power supply:
Please order power supplies as separate accessories. - USB 2.0 Full Speed Device (12 Mbit/s)
- Addressable as virtual COM interface under
Windows 98 / Me / 2000 / XP / Server 2003 / Vista / Server 2008 (x86 and x64) - Supports Mac OS 8, OS 9 and OS X
- Direct Linux support without additional driver from kernel version 2.4.0
- RS485 2 and 4 wire compatible
