3 – Introduction
IF62 and IF63 are optical fiber modules specifically designed for transmission of
data output by an SSI encoder, sensor or measuring system. These modules
consist of a transmitter (IF62) and a receiver (IF63) that are coupled to form an
SSI absolute signal transmission system through optical fibers. The optical fibre
transmitter module IF62 converts the electrical data of a standard encoder or
sensor equipped with Synchronous Serial Interface (SSI) into optical fibre
signals. Then the optical fibre receiver module IF63 converts the optical signals
back into electrical SSI signals. They are available in two supply voltage variants
for reliable transmissions up to 2,000 m (approx. 6,550 ft).
By means of the two rotary switches located in the front side of the fibre optic
transmitter module it is possible to set the SSI resolution from 1 bit to 99 bits.
Both modules are equipped with LEDs; they are intended to show visually the
operating or fault status of the unit. In addition, the receiver module also has a
general alarm open-drain and active-low output.
The optical fiber modules are mainly used for signal transmission in
environments with strong electromagnetic interference or when a potential
separation is necessary due to high ground potential differences between signal
source and signal processing equipment.
High ground potential differences generally appear in applications with long
distances between the encoder/sensors and the PLC or any other processing
electronics.
