66201 Serial Isolator for the control cabinet by Wiesemann & Theis GmbH
Get a quote
The Wiesemann & Theis 66201 is a serial isolator engineered for control cabinet integration, providing galvanic isolation of a minimum 1kV DC between all terminals. This device features selectable RS422 and RS485 interfaces via a 9-pin SUB-D adapter, supporting operating modes for RS422, RS485 4-wire, and RS485 2-wire with automatic control. It handles baud rates from 0 to 3 Mbaud with any data format. The switching time from data send to receive is approximately 10 microseconds for RS485 automatic control. A connectable termination network is included for RS485 operation. Supported signals comprise RxD, TxD, CTS, and DTR. Power is supplied via a plug-in screw terminal with a 5.08mm spacing, labeled L+ and M, requiring 12 to 24V AC/DC (plus or minus 10%). Current consumption is typically 70mA at 12V DC and 35mA at 24V DC. Status monitoring is provided by one Power LED and one Data LED.
