Fiber Optic (Send) Module for RS422 / HTL Signals (up to 3000m) LW213:

Fiber Optic (Send) Module for RS422 / HTL Signals (up to 3000m) LW213

Short description on LW213:

The LW213 and LW214 fiber optic modules together form an optical transmission system for the data transmission of incremental sensor or encoder signals via an optical waveguide.

One can connect to differential signals of any other source with RS422 or push-pull HTL levels (eg. incremental length measuring systems, glass scales, etc.).Transmitter and receiver modules each have four completely independent channels with differential inputs and outputs. Signals can be transmitted on all four channels with a maximum data rate of 2 Mbit/s.

The component with the designation LW213 serves as a transmission module for a light wave transmission up to 3000 meters. It converts the incremental signals of conventional sensors, measuring systems or rotary encoders into optical fiber signals.

Optical Fiber (Receiver) Module with Incremental Output LW214

Short description on LW214:

The optical transmission modules LW213 and LW214 together form a system for reliable and fast data transmission of industrial signals via an optical fiber.
