Protect your RS422/RS485 connection against interference and voltage differences with this optical isolator. Galvanic isolation up to 1 kV ensures a stable data flow, even at high baud rates up to 250,000.
When do you choose this product?
When do you need an optical isolator?
An optical isolator provides galvanic isolation for RS422/RS485 interfaces and RS485 bus systems. It electrically separates the connected systems from one another. The isolator operates in RS422 or RS485 mode, in 2-wire or 4-wire operation, with automatic control.
Why choose this baud rate and isolation voltage?
The isolator supports baud rates from 0 to 250,000 baud and is suitable for any data format. The isolation is at least 1 kV. For RS485 operation, a termination network can be switched on.
Flexible power supply for different installations
The isolator requires a power supply of 12 to 24 volts DC or AC. A power supply is not included with delivery. Optionally available are a plug-in power supply and a DC switched-mode power supply for DIN rail mounting, which are ordered separately.
Practical connection via standard connectors
The isolator is fitted with 9-pin Sub-D connectors for the serial connections. The article number of the isolator is 11130226. The housing is made of plastic and suitable for DIN rail mounting in accordance with DIN EN 50022-35.
