Maximum capacitive load - 10 nF
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.
19.2.13 mA input module (MIM)
19.2.13.1 Introduction
The milli-ampere input module is used to interface transducer signals in the –20 to +20
mA range from for example OLTC position, temperature or pressure transducers. The
module has six independent, galvanically separated channels.
