4.8. Power supply
MT-101
may be powered by 18...26,4 V (AC) or 10,8...36 V (DC).
NOTICE!
Exceeding the range of power supply may cause faulty operation or damage
the module!
The module may work with auxiliary battery supply securing operation for some time after
main supply failure. In order to discriminate whether the module is powered from battery or
from main supply the module has a binary input marked
UPS
, where the signal informing
that main supply has failed. Main supply voltage drop below 10,8 V raises the
FS1_ups
system flag. The flag may be used for rules processing. The input may be used to signal
main supply failure and switch over to battery supply.
4.9. Housing
MT-101 module is encapsulated in standard housing made of plastic compliant with safety
requirements and protecting the module in standard operating environment.
The applied solution complies with standard industrial requirements for DIN rail mounting.
5. Connections scheme
This chapter shows standard configurations of connections securing proper operation of
MT-101
module's integral inputs in all available operating modes.
5.1. Binary inputs I1....I8
Integral binary inputs marked as
I1....I8
may work in both positive and negative logic
making circuit design very easy.
Binary inputs
I1....I8
– in positive logic:
