Characteristics

You can configure pulse inputs for either a 2mA
pull-up to 24VDC or a 2mA pull-down to ISO_GND.
 Configurable as either medium speed 1 ms filter
(0 – 300Hz) or a high speed 30µs input filter (0-
10.5kHz). Only use low speed for a digital input
(DI).
Figure 3-9 shows how to wire the pulse input. In the figure, AIDIPI_3 is shown as a dry-
contact pulse input; AIDIPI_4 is shown as an externally sourced pulse input. Pin 5
(ISO_GND) serves as the ground connection for AIDIPI_3 and AIDIPI_4.
