DescripciónThe PSM-2 Power Supply Module provides excitation power for sensors used with the OM-320, OMP-MNL and OMP-MODL dataloggers. The PSM-2 can supply 100 mA of current … sufficient to power up to five 4 to 20 mA loops. Alternatively it can be used as a voltage source for sensor excitation. A 5 Vdc output is standard and one additional output is available which can be jumper programmed in the field for 10, 15 or 24 Vdc output. Four standard versions of the PSM-2 are available for use with the OM-320, OMP-MNL and OMP-MODL dataloggers or as a stand-alone module. The PSM-2 draws its power from the standard datalogger D-cells or an external supply. The PSM-2 outputs are cycled ON/OFF by a software controlled low-level 5 Vdc input from the associated datalogger which provides power only as required for sampling and minimizes power consumption and maximizes battery life. An LED indicator lights when the outputs are ON. Sensor excitation is easily programmed into the datalogger via the HyperWare software supplied with the datalogger.
