DIM Digital Input Modules.
Each DIM (Figure 3-8) provides an
expansion capability of four additional digital input channels. The DIM does not have
power terminals since operating power is supplied from the controller by way of the LEM
cable.
Figure 3-8. Digital Input Module.
Digital input terminals for the DIM are listed in Table 3-10. It should be noted that digital
input signals must have an amplitude of 24Vac/Vdc powered from an external source. If
the input signals are from a DC source, ensure the correct polarity of connections as listed
in Table 3-10. Avoid running the signal cable through ducts where adjacent cables may be
connected to digital or other switching devices.
