Logix 1400 Digital Positioner Overview
The Logix 1400 digital positioner is a two-wire, F
OUNDATION
fieldbus compliant, digital valve positioner. The Logix
1400 digital positioner also utilizes the fieldbus protocol
to allow two-way remote communications with the posi-
tioner. The Logix 1400 digital positioner can control both
double- and single-acting actuators with linear and rotary
mountings.
Since the positioner is insensitive to supply pressure
changes and can handle supply pressures from 35 to 150
psig, a supply regulator is usually not required; however,
an air filter is required due to the close clearances in the
spool assembly.
NOTE: The air supply should conform to ISA Standard
S7.3 (a dew point at least 18
° Fahrenheit less than
ambient temperature, particle size below one micron, and
oil content not to exceed one part per million).
