High-speed digital inputs interface
(HS_GPI1, HS_GPI2)
The high-speed (HS) non-isolated digital inputs are ready for 5 V levels but are 24 V tolerant. Next table show
their electrical specifications.
Specification
Value
Number of inputs
2 (HS_GPI1, HS_GPI2)
Type of input
ESD protected
Differential and single ended
ESD capability
IEC 1000-4-2 (ESD) ± 12 kV (air), ± 6 kV (contact)
GPI Pull-up resistors
Pull-up resistors ensure the desired logic state when the sensor (transistor or relay) is in off-state.
NPN pull-up resistor value must be chosen in order to ensure
≥
4 V at the GPI pin considering the 30 k
Ω
input resistance. For a sensor supply of 5 V, 1 k
Ω
is recommended. For a sensor supply of 24 V, 10 k
Ω
is
recommended.
Defect logic value
Triton Go high-speed inputs are default low-level (OFF). When no signal or load is connected, the board
will detect a logic low.
