SP-SDI
Input circuit (I1 to 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
Max. 10 nF
Synchronous time
4 ms to 30 ms, configurable
Number of inputs
8
Test outputs (X1 to X8)
Number of outputs
8 (with two test signal generators)
Type of output PNP semi-conductor, short-circuit-proof, cross-
connection-monitored
Output voltage
16 to 30 V DC
Output current Max. 120 mA at both of the two test signal genera-
tors (X1/X3/X5/X7 or X2/X4/X6/X8)
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 32 inputs of testable sensors with 30 mA
and 64 inputs of SP-SDIO or SP-SDI modules.
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

Do not connect any other safe inputs in parallel when the reverse current could lead to a
HIGH state at the other input.
