Resistance input
Measuring range 0 .. 50 kΩ
Temperature input
Measuring range -50 .. 150 °C
Can be used with Bosch Rexroth
TSA or TSF (PTC) temperature sen-
sors or Bosch NTC temperature sen-
sors. For details see API manual.
Analog voltage input
Measuring range nominal 0 to 5 V
Resolution 12 bits
Resolution 1.44 mV / bit
Accuracy ± 3 % at 5 V
Filter limit frequency 1647 kHz
Digital input
Switching threshold configurable in soft-
ware (max. 5 V)
Frequency input
For frequency sensors that switch between
typically 0 V and 5 V (e.g. Bosch DG23i)
Low level < 1.7 V / high level > 3.5 V
Measurable range up to 20 kHz
▶ minimal pulse length 25 µs
▶ the lower frequency limit depends on the
period used in software for the fre-
quency acquisition
Do not use for active frequency sensors
that switch or pull-up to battery voltage!
