RELAY CONNECTION WARNING (FOR DIRECT LOAD SWITCHING)
The Rosemount 2110 requires a minimum current of 3mA, which continues to flow when the
2110 is ‘off’. If selecting a relay to wire in series with the 2110, the user must ensure that the
drop-out voltage of the relay is greater than the voltage which will be generated across the
relay coil when 3mA flows through it.
NOTE (FOR DIRECT LOAD SWITCHING)
DPST = ‘Double Pole, Single Throw’ (on/off) switch - must be fitted for safe disconnection of
the power supply. Fit the switch as near to the 2110 as possible. Keep the switch free of
obstructions. Label the switch to indicate that it is the supply disconnection device for the
2110.
