Issue Description

1

Voltage Spike across TX Transceiver Line

Occasional voltage spikes fixed by adding
a diode to Pin 1 of the transistor.

4.1 Issue 1: Voltage Spike Across the TX Line of the Transceiver

Affected PCB version: E1

Board Modification Sticker: M1

Severity:

High

The original design of the IO Link breakout board resulted in occasional voltage spikes on the TX line of the
transceiver. A fix was implemented by rotating transistors Q4, Q5, Q6, Q7, Q8, Q9, Q10 and Q11 and adding a
diode in line with Pin 1 of the transistor.

This Mod was applied to all boards shipped with a 1st revision PCB.
