The PSM Power Supply Module is a rugged module that can
be used to provide excitation power for sensors used with
the ModuLogger, Mini and HyperLogger portable and
remote site data logging and alarming systems. The PSM-x
can supply 100mA of current... sufficient to power up to
five 4-20mA loops. Alternatively it can be used as a voltage
source for sensor excitation. One 5Vdc output is standard.
An additional voltage output is available which can be field
jumper programmed in the field for 10, 15 or 24Vdc output
(custom output voltages are available. Contact
Logic Beach).
Four standard packaged versions of the PSM are available
for use with the HyperLogger, ModuLogger and Mini
portable data logging systems. The PSM is offered as a stand-alone
module, or can be incorporated into loggers. The PSM draws
its power from the standard data logger D-cells or an external
supply. For connection to the logger D-cells, a pigtail
with mating connector projects from the PSM. This pigtail
can then be used to connect to the mating connector provided
on the Logic Beach data logger battery pack. Alternatively,
external power can be supplied to the PSM via terminal strip
connections on the PSM.
The PSM outputs are cycled ON/OFF by a low-level control
input from the associated logger. Typically, this control
input is controlled by an output from the associated logger,
providing power only as required for sampling... minimizing
power consumption and maximizing battery life. An LED indicator
lights when the outputs are ON providing visual feedback
of operation during installation
