relay outputs
Function of quantity Trip and signal relays
Max system voltage 250V AC/DC
Number of outputs 6
Test voltage across open contact, 1 min 1000V rms
Current carrying capacity:
Continuous 8A
1.0s 10A
Making capacity at capacitive load with the maximum
capacitance of 0.2 μF:
0.2s 30A
1.0s 10A
Breaking capacity for DC with L/R ≤ 40ms 48V / 1A
110V / 0.4A
125V / 0.35A
220V / 0.2A
250V / 0.15A
Maximum 72 outputs may be activated simultaneously with influencing
factors within nominal range. After 6 ms an additional 24 outputs may be
activated. The activation time for the 96 outputs must not exceed 200 ms.
48 outputs can be activated during 1 s. Continued activation is possible
with respect to current consumption but after 5 minutes the temperature
rise will adversely affect the hardware life. Maximum two relays per
BOM/IOM/SOM should be activated continuously due to power
dissipation.
21.2.10 Binary input/output module (IOM)
21.2.10.1 Introduction
The binary input/output module is used when only a few input and output channels are
needed. The ten standard output channels are used for trip output or any signaling purpose.
The two high speed signal output channels are used for applications where short operating
time is essential. Eight optically isolated binary inputs cater for required binary input
information.
