24V Power Supply for 4-20mA Sensors w/ Backup Battery


A 24V power supply for use with most 4-20mA sensors. It is required when connecting the humidity transmitter to any Sensaphone that does NOT provide external 24V DC power. The Sensaphone SCADA 3000 and Express II are the only units that supply their own power.
