Technical details
I/O connections
he TPU has six freely programmable inputs and
outputs:
z
Model: Open-Drain output (wired ground)
with recovery diode / input with 15 kOhm
pull-up resistor against the device operating
voltage
z
Only ohmic and inductive loads are allowed
(no capacitive loads!)
z
Maximum current carrying capacity: 100 mA
per connection
z
Dielectric strength smaller than/equal to the
connected device operating voltage (howe-
ver, max. 32 V)
z
Recovery diode for relay (inductive loads)
included; use of device-specific power supply
(pins 4, 5, 6) is required for this
