Typical Connections to the Interface Module (IFM) Terminal Block
Pin assignments of the IFM terminal block for I/O, power, shield, and
ground connections are as follows: (For example, we show connections
for one axis with a Temposonics LDT and power supply.)

Connect the
"15V dc power supply to pin 50 (Com), pin 33 (+V), and
pin 32 (–V). Connect pin 51 (GND) to earth ground with 3/8” wire braid
(as short as possible).
Typical Fusing of the Interface Module (IFM) Terminal Block
The Interface Module (IFM) Terminal Block is wired for fusing of
(
"V) to each LDT. Provide proper fusing (T500L 250V, typical) for
each axis using fuse clips on the IFM terminal block.
Example Connections for Temposonics II Differential Inputs
Use differential inputs when connecting LDTs to the IFM terminal block.
