Connecting Field Wiring to the D20E Module
This chapter describes the I/O connection for each type of D20E module:
• D20E-A analog inputs module on page 87
• D20E-K control outputs module on page 89
• D20E-S digital inputs module on page 95
• D20E-C combination inputs and outputs module on page 97
Field wiring is connected to the D20E modules at terminal block TB2.
D20E-A analog inputs module
The D20E-A supports up to 32 differential analog inputs. The field terminations for analog
inputs are provided by TB2-1 to TB2-48 and TB2-51 to TB2-98 (See
Table 21 for details).
One shield termination is allocated for each input.
Table 21 lists the TB2 terminal block connection assignments for the D20E-A.
The wiring connected to terminal block TB2 must not have exposed accessible
conductors.
The wire and cable connected must have at least a +80 °C temperature rating.
