Cat. No. 1771–ID16

The module has 17 indicators (Figure 4), consisting of 16 input status indicators and an active indicator. The 16 status indicators will light when the field load has been applied to the field wiring arm of the module.

At power up, all indicators will light for about one second. This is a self-test feature of the module. The inputs are not “on” during this test.

The active indicator will light when the module has successfully started up and has initialized.
