I/O Diagram
A more functional representation of the control (I/O) connections are shown
in Figure 5.
Figure 5 - Control I/O Connections in Powered-Down State
➊ See Table 44 for control function assignment to the input IN1 and IN2. Connect the appropriate external contacts (#1 and #2) to the
inputs.
➋ Inputs IN3, IN4, and IN5 are available when an optional I/O extension card is present. 825-PIOD inputs are rated 120V AC/DC. 825-PIOR
inputs are rated 24V AC/DC.
➌ See Table 42 for mapping protection elements to the Trip output. See Figure 7 and Figure 16 for typical control circuit connections.
➍ See Table 43 for mapping protection and/or control elements to the Aux outputs. Outputs Aux3 through Aux6 are available when an
optional I/O extension card is present.
➎ Analog Output is available when an optional I/O extension card is present.
➏ You can connect up to six thermistors (PTC) in series. See Table 2 for PTC cable requirements.
➐ Use up to 500 meter long Simplex 62.5/125 mm fiber-optic cable (ST/ST).
➑ Available when an optional DeviceNet Communications Protocol Card is present.
