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
