Max. 20 mA
1.5 kΩ effective reverse resistance for supply cur-
rent
Max. 10 nF

8 (with two test signal generators)
PNP semi-conductor, short-circuit-proof, cross-
connection-monitored
16 to 30 V DC
Max. 120 mA at both of the two test signal gener-
ators (X1/X3/X5/X7 or X2/X4/X6/X8)
Thus, a maximum of eight testable sensor cas-
cades are possible per module with a maximum
of 30 mA each.
The total current of the MSI 400 system is limited
to a maximum of 1.28 A. This corresponds, for
example, to 32 inputs of testable sensors with
30 mA and 64 inputs of MSI-EM-IO84 or MSI-
EM-I8 modules.
1 to 25 Hz, configurable
1 to 100 ms, configurable
