SP-SDIO
Input circuit (I1–I8)
Input voltage HIGH
13 to 30 V DC
Input voltage LOW
-5 to +5 V DC
Input current HIGH
2.4 to 3.8 mA
Input current LOW
-2.5 to 2.1 mA
Input reverse current with ground
breakdown
2
Max. 20 mA
1.5 k
Ω
effective reverse resistance for supply current
Input capacity
10 nF
Synchronous time
4 ms to 30 ms, configurable
Number of inputs
8
Test outputs (X1, X2)
Number of outputs
2 (with 2 test signal generators)
Type of output PNP semi-conductor, short-circuit-proof, short-
circuit-monitored (configurable)
Output voltage HIGH 15 to 30 V DC (max. 1.8 V drop to terminal A1 on
the controller module)
Output resistance LOW
22 Ω ± 10%, voltage limited at about 10 mA
Output current Max. 120 mA at a test output (X1 or X2)
Thus, a maximum of eight testable sensor cascades
are possible per module with a maximum of 30 mA
each.
The total current of the samosPRO system is limited
to a maximum of 1.28 A. This corresponds, for exa-
mple, to a maximum of 32 testable sensor cascades
with 30 mA each plus 64 tactile sensors at the in-
puts of expansion modules with 5 mA each.
Test pulse rate (test period)
1 to 25 Hz, configurable
Test pulse duration (test gap)
1 to 100 ms, configurable
Load capacity
1 µF for test gap ≥ 4 ms
0.5 µF for test gap 1 ms
Line resistance
< 100 Ω
