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
should be activated continuously due to power dissipation.

17.2.9.1 Introduction
M6939-3 v6
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.
17.2.9.2 Design
IP10635-1 v2
M1718-3 v4
The binary input/output module is available in two basic versions, one with
unprotected contacts and one with MOV (Metal Oxide Varistor) protected contacts.
Inputs are designed to allow oxide burn-off from connected contacts, and increase
the disturbance immunity during normal protection operate times. This is achieved
with a high peak inrush current while having a low steady-state current, see figure
"". Inputs are debounced by software.
Well defined input high and input low voltages ensures normal operation at battery
supply earth faults, see figure 308.
The voltage level of the inputs is selected when ordering. Alternative connectors of
Ring lug or Compression type can be ordered.
