3.8 Universal Digital Input (UDI) Modules
Universal Digital Input (UDI) modules include six inputs which you can
individually configure as high speed counters or polled inputs.
UDI modules consist of a UDI PCB, either a terminal board assembly
for local termination or a header block assembly for remote termination,
a terminal housing assembly, an LED board, as well as I/O assembly
and mounting hardware.
Note:
Because UDI modules are interrupt driven, you can only install
them in the first four I/O slots.

Inputs (UDI)

Each UDI supports/includes:
Field input can be a driven signal, an
open collector output, or a relay
contact. Inputs handle 24V
Jumper to configure point for debounce
enable or debounce disable.
Software configures point as a polled
input with a 30 millisecond filter or as a
16-bit high speed counter (totalizer)
with a 20 microsecond filter.
Maximum input frequency of 10 KHz
with a nominal input current of 5mA.
16 bit counter.
Signal conditioning circuitry and
bandwidth limiting circuitry. Software
selectable delays for signal
conditioning.
Each input is optically isolated from the
field device.
Each input has an electrical isolation of
500Vdc to chassis and 1500Vdc to
system logic.
Surge protection. Protection from a
31dc transorb (across input and to field
common) that meets ANSI/IEEE
standard C37.90-1978.
