DIN rail power supply MAQ20-PWR3

programmableredundant

The MAQ20-PWR3 is a load share power supply module for expansion, standby and redundant power on the MAQ20 data acquisition and control system. The MAQ20 system is made up of DIN rail mounted, programmable, multi-channel, signal conditioning input and output modules and communications modules. System power is connected to the communications module, which in turn powers the I/O modules. The communications modules provide 5V DC at up to 3A through the system backbone, which is more than adequate for most typical systems where standard input modules consume 150mW. However, some MAQ20 I/O models deliver significant amounts of power to field I/O devices, and when many of these are used in a single system, power supply requirements may exceed the power output of the communications module. To meet these high power consumption needs, one or more MAQ20-PWR3 load share power supply modules can be installed in any I/O module slot on a single backbone to provide the additional power needed.
