WisyCom MRK16 - Option - GPIO Board

MRK16 16 channels ultra-wideband rack unit
12
Option - GPIO BOARD (GP1)
When the MRK16 is equipped with the GP1 option, a SubD 44-pin connector is available on the
rear panel. This connector allows for the management of the following:
- 16 outputs: These outputs provide 28Vdc or 20Vac with a maximum current of 70mA. Out-
puts are normally open and isolated, meaning they are typically not connected to ground or
power by default, and each output is electrically separate from the others.
- 16 inputs: These inputs accept voltages ranging from 4Vdc to 28Vdc with a maximum current
of 1.5 mA.
This configuration provides versatile control and interfacing capabilities for various applica-
tions requiring both output and input management through the SubD 44-pin connector on the
MRK16.
This means that the outputs are typically not connected to ground or power by default, and
each output is electrically separated from the others.
Common ports share pins for 8 inputs and outputs.
For example, pin 33 serves as the common port for inputs 1 to 8. This suggests that pin 33 is
used as a common reference or ground point for these inputs.
Two power supplies are provided:
- Pin 19 provides one power supply (5V, max 200mA).
- Pin 41 provides another power supply (5V, max 200mA).
- These power supplies have separate and isolated grounds.
- Pin 34 serves as the ground for one power supply.
- Pin 26 serves as the ground for the other power supply.
