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.
