High-speed, Intelligent Interface Modules
with Seven Operating Modes Convert Single
or Dual Input Pulses to Display Values
50-kHz input range and 0.006% accuracy for sophisticated
control.
A wide selection of outputs: relay, transistor, BCD, linear, or
communications.
Maximum/Minimum value hold, set value write protection, and
more.
Banks with four comparative output values and four prescale
values.
Prescale function available, which displays in units of actual
physical parameters (length, volume, etc.).
Set value teaching, linear output range teaching, and prescale
teaching are available using actual measured values.
Displays values in hours, minutes, and seconds in operating
mode 6.
A startup compensation time parameter keeps the
measurement operation from sending an unnecessary output
for a preset period up to 99.9 s.
Built-in sensor power supply (12 VDC, 80 mA).
Compact 1/8 DIN size.
Conforms to EMC standards, EN61010-1 (IEC61010-1).
UL/CSA approved.
