GPIO Pin/Function Assignment Table
Pin # Function
PE Ground Return*
*Ground Return electrically connected through cable assembly to INPUT,
OUTPUT return Pins 4, 7, and 11.
GPIO Inputs
The GPIO inputs are rated for a 10-48 Volt input signal.
Both the high and the low signal contact are exposed and are
isolated to 1500 Volts. Input impedance is 1800 ohms mini-
mum.
Signal Description
Vin(High) Input Voltage High
Vin (Low) Input Voltage Low
GPIO Outputs
The GPIO outputs consist of a power MOSFET photovoltaic
relay. This high and low contact are exposed and are isolated
from the reader by 1500 Volts. Transient suppression limits out-
put voltage spikes to 65 V DC.
Signal Description
Leakage Switch Output Leakage current
Current High (micro amps)
(High)
Vsat(Low) Switch Output ON saturation

GPIO Power
The interface includes access to 12 Volt power. This supply cur-
rent limits at 0.25 Amps. This supply return is common to the
unit input return power. The intended purpose of this supply is
to power local loads such as relays or indicators.
