4 Logix 3200MD
Positioner Overview
The Logix 3200MD digital positioner is a two-wire 4-20 mA input digital
valve positioner. The positioner is configurable through the local user
interface. The Logix 3200MD utilizes the HART protocol to allow two-
way remote communications with the positioner. The Logix 3200MD
positioner can control both double- and single-acting actuators with
linear or rotary mountings. The positioner is completely powered by
the 4-20 mA input signal. Start up current must be at least 3.6 mA
without AO card or 3.85 mA with AO card.
