USB interface AC-1000

USB 2.0communicationModbus

The AC-1000 are communication adapters with galvanic insulation and raíl DIN enclosure, designed to changes the RS-232 communication signals to the correct electrical levels required by RS-485. The AC-1000/LM version are a new concept of communication adapters for make easy to the processes engineer to design distributed acquisition and control system networks. This version .../LMacting as Modbus Communication Master allows data exchanges among instruments of PAC control type in field and at horizontal level with no-needing PC or PLC control. • 1 RS-232 port for connect to PC • 1 RS-485 port for connect to field of bus • 1 RS-485 port for bus repeater • LINKER with 40 progamming steps (version ../LM) The USB-485 adapter is destined to the conversion of USB 1.1 and USB 2.0 standard ports with RS-485 interface devices in process control systems. This adapter does not interfere into the structure of data transmission and is compatible with many industrial protocols • Aerial RS-485 a USB compatible con USB 1.1 y USB 2.0 • Supports MODBUS RTU protocols etc. • No interfeence into structure of data • Baud-rate up to 115,2 kbps • USB type B (USB cable included) and terminals for RS-485 • Self-powered from PC • Installation software included
