Figure 3-7 LDT Pinout Diagram Input Option L1
LDT Input (FMIP02) Input Option L1
This module will accept an output from a controlled pulse, start stop pulse or variable pulse
magnetostrictive LDT. (See Figure 3-7). This card accepts a wide range of LDT inputs and
provides faster updates than the variable pulse module as described on page 12.
The pulse width signal is converted to position data which the monitor displays. The module
also provides +24 VDC to supply power to the LDT. The monitor was designed to work with
the Gemco 951 or 952CP & RS LDTs. However, other LDTs can be used with the PLC
Interface Module. If you are using a different type of LDT, contact the factory for wiring and
programming instructions. The terminal wire size for all positions is No. 22-12 AWG.
The reset-to-preset input is an edge sensitive input that resets position data to a preprogrammed
value. A 5-24VDC source applied to these terminals activates the input. For programming of
reset value, see Chapter 4: Programming.
Digital Output (FMOD01) Output Option D1, D2 or D3
This module will output Binary, BCD, or Grey Code digital outputs in either current sinking,
current sourcing, or TTL level outputs. See Fig. 3-13A & B and Fig. 3-14 for wiring details. It
also contains a 5-24VDC source input for freezing the digital data while the PLC reads it. See
page 37, Latch/Synchronize Handshake.
