The 1444 DYN04-01RA includes two discrete TTL class input channels.
These let users physical wire an input to the module that can be used in
any of several described manners.
Function
Description
Trip Inhibit/ Bypass
Inhibits trips with all voted alarms
that define the Logical Input as its
control
Alarm/Relay Reset
Resets all latched voted alarms
where the alarm condition has
cleared, which resets any associated
physical relays.
Voted Alarm SPM Control
Manages Setpoint Multiplication
for measurement alarms that are
inputs to the associated voted
alarm.
Voted Alarm Gate Control
Manages Alarm Gating for the
associated voted alarm.
Voted Alarm Logic Control
Use this to wire an external input
that, when actuated, forces the
associated Voted Alarm to actuate,
and therefore any relays associated
with it. See I/O Control on the Voted
Alarm page for further information.
Speed 0 Fault
If wiring a TTL tacho source to the
terminal base, rather than via the
Speed 1 Fault
local bus, this input can be used to
communicate the tacho channel
status.
