1.6.1. Pin Description
Table 1. GPIO pin descriptions
The Isolated GPIO input is quite different to the Non-isolated GPIO input:
Pin GPIO Cable
Colour Name Description
1
Red Non-is3.3
VDC voltage
signal The +3.3VDC rail is intended to power such things as input
sensors
It is currently limited to 100mA to protect the Spider in the event
that this output is shorted
2 Black Non-isolated
ground General purpose ground
3 Grey Non-isolated input
1 with basic
protection The basic protection consists of current limiting resistors and
TVS diodes
There is provision for adjusting the default Low-Pass frequency
of 106kHz
Maximum voltage is +3.3 VDC
4 Yellow Non-isolated input
2 or analogue
input
5
Orange Isolated output
ground The isolated outputs share a common ground connection. This is
separated from the Spider Ground
6 Blue Isolated output 1 The isolated output has an open collector configuration. The
specification must be strictly followed.
An open collector output allows the 3rd party to pull the voltage
up to a large range of voltages and the Spider will drive this
voltage low to activate the output.
IMPORTANT
• Maximum voltage is +80 VDC
• Maximum current must be kept < 30 mA
• This is done by selecting an appropriate resistor
value
• Failure to limit the current and/or voltage will
result in permanent damage to that particular output port
7 Brown Isolated output 2

Purple Isolated input
ground The isolated inputs share a common ground connection. This is
separated from the Spider Ground
9 White Isolated input 1 Voltage input range of +3.3 VDC ~ +12VDC (Absolute Max +15
VDC) without 620 ohm resistor.
Voltage input range of +9 VDC ~ +32VDC with 620 ohm resistor.
IMPORTANT
• Failure to limit the current and/or voltage will
result in permanent damage to that particular input port
