Data sheet:
Interface - Plastic fiber optic <> RS422/RS485 Industry
Also transmit industrial interfaces with noise immunity
The model 61201 Interface transmits serial RS422 or RS485 data via plastic duplex fibers over a distance of up to 100 meters. The external supply voltage ensures stable conditions for reliable operation of the often low-impedance terminated differential interfaces.
Properties
Interfaces:
- Selectable RS422 / RS485 interface
- 9-pin Sub-D plug
- Fiber optics interface
- Direct connection of the fiber optic cable without a connector
- Alternate names: POF (polymer optical fiber, plastic optical fiber)
Management and connectivity:
- The interface is very easy to install:
- Cut the fiber-optic cable with a sharp knife at right angles.
- Insert into patented adapter of the W&T interface.
- Plug the adapter into the PC.
- That’s it!
- No re-configuration of transmission parameters required
- 100% protection against interfering radiation
- Electrical isolation
- Lightning protection
Power supply:
- External
- 12V-24V AC/DC via plug-in screw terminal
- Galvanically isolated power connection
