Universal, Signal Conditioners with Alarms
Description
The Micromann series are fully isolated,
microprocessor based, signal transmitters
for use with process measurement signals
and sensors. They also have two alarm
channels.
You can program all features of Micromann
operation through the front panel keypad.
When the set-up is complete, you simply
remove the security link to protect the
setup.
The analogue output calibration is simple
and sets up both current and voltage
outputs. So, you can use any current or
voltage output range without recalibration.
You can tailor each alarm’s operation
individually during setup. If necessary, you
can also allow setpoint adjustment (from the
front panel) during normal operation.
The Micromann can be ordered with one
SPDT contact alarm instead of the standard
normally open relay contacts.
Alarm operation can be set to ‘manual reset’
so that active alarms will remain tripped until
manually cleared.
