Rosemount 2130
Direct Load Switching
Cassette
• Direct load switching (2-wire, Red label)
NOTE:
A DPST (Double Pole, Single Throw) on/off switch must be installed to safely
disconnect the power supply. Install the DPST switch as close as possible to
the Rosemount 2130. Keep the DPST switch free of obstructions and label
the DPST switch to indicate it is the supply disconnection device for the 2130.
RELAY CONNECTION WARNING:
The Rosemount 2130 requires a minimum current of 3 mA, which continues
to flow when the output is ‘off’. If selecting a relay to wire in series with the
2130, ensure the drop-out voltage of the relay is greater than the voltage
generated across the relay coil.
