DIN RAIL MOUNT
SIGNAL CONDITIONER

FOR AC TRANSDUCERS

LDX-D

U Operates on 10 to 30 Vdc
U ±10 Vdc or 20 mA

Selectable Output

U Compatible with

AC LVDTs

The LDX-D is a DC-powered
conditioning module that can accept
a wide range of analog inductive
transducer types owing to its wide
input gain. The signal polarity, span,
and offset are adjustable. Output is
selectable: ±10 Vdc voltage or
±20 mA current.

The housing is a standard DIN rail
enclosure that can clip directly to a
35 mm top-hat rail (TS35 EN50022).

Transducers are connected
via the screw terminals on the
front of the LDX-D. Internal links
and front-panel fine-adjustment
potentiometers facilitate setup.

By linking 2 LDX-D modules, users
can perform some analog arithmetic
functions, such as A + B, A – B,
(A + B)/2 and (A – B)/2.
