Analog Output Process Current and Voltage Output
Modules are offered with 4-20mA and 0-20mA process current
output or up to ±10V voltage output with drive capability; they control
motors, drive valves and perform many other crucial process opera-
tions. Up to eight channels of output on the modules results in physi-
cally small control systems and low cost per channel. Output modules
have each field-side channel galvanically isolated from all others to
eliminate common mode signal problems and offer maximum durability.
Signal ranges are user selectable and channels can be independently
configured to match the most demanding applications. Processing
power within each module allows users to enter waveshapes to output
to field devices. Power-on delay and default channel states guarantee
proper process performance upon startup and during power interrup-
tions. Field I/O connections are made through a pluggable terminal
block with positions provided for the termination of wiring shields.
Discrete Input/Output Modules have multiple channels of
input and output per module. Solid state circuits provide or interface to
discrete signals up to 60V and 3A. In addition to standard discrete I/O,
these modules provide advanced special functions including Pulse/
Frequency Counter with or without de-bounce, Waveform Measure-
ment, Time Between Events, Frequency Generator, PWM Generator,
and One-Shot Pulse Generator. Alarms can be set on the discrete
input channels.
