The 40-655A-002 module contains 7 separate 4-channel
multiplexers with 2-pole switching, suitable for signals up to
220VDC (125VAC).
It can be configured in many multiplexer switching formats (see
schematic overleaf), for example 56-channel 1-pole, 28-channel
2-pole, etc. The 40-655A can be either factory configured or later
re-configured by the user to form a different multiplexer function.
The 40-655A can be operated as a conventional multiplexer
with break-before-make action when a new channel is selected.
Alternatively, product variants can be supplied that allow multiple
channels to be simultaneously selected.
The 40-655A channel selection configurations have been revised
from the 40-655. The 40-655A defaults to single channel selection
with multiple channel selection variants defined by use of a suffix.
The 40-655A has been specifically designed for switching POTS,
ISDN or xDSL telephony signals. Please contact Pickering sales
office for more assistance with Telecom switching applications.
