Model LF612 converters
Input signals
Analog signal — the voltage signal from detector, proportional to process flow rate (for LF612 separate type converter).
Digital input DI (opt.)
Signal type: 20 to 30Vdc voltage signal
Input resistance: 2.7kΩ
Number of inputs: one point
DI function — One of the following functions can be assigned to the optional DI signal.
Range switching — Selects either the higher or lower range in the unidirectional or bidirectional
Totalizer control — Starts and stops the
Zero adjustment — Executes zero adjustment
Output signals
Current output:
Note: The current output cannot be used with the
Digital outputs — One point (std.) and one more point is optionally available as follows.
Digital output DO1 (std.):
Output type: Transistor open collector
Number of outputs: One point
Output capacity: 30Vdc, 200mA maximum
Digital output DO2 (opt.):
Output type:
Output capacity: 150Vdc, 150mA maximum or 150Vac (peak to peak), 100mA maximum
DO1 and DO2 functions — One of the following functions can be assigned to DO1 (std.) and/or DO2 (opt.)
•Pulse output (available only for DO1, DO2) Pulse rate: 3.6 to 36,000,000 pulses/hr (DO1)
3.6to 360,000 pulses/hr (DO2)
(Over 3,600,000 pulses/hr,
Pulse width: 0.5 to 500ms (but less than half of the period for 100% flow rate)
Note: The same and simultaneous pulse is not available between DO1 and DO2.)
•
•High, High high, Low, and/or Low low alarm outputs (Note 2)
•Empty pipe alarm output
•Digital Output Active Status (DO1 and DO2) (Note 2)
•Preset count output
•Converter failure alarm output
Note 1: Two outputs (DO1 and DO2) are needed for
Note 2:Normal Open (default set) or Normal Close is selected for alarm outputs when programming.
When power failure occurs, unit will be fault to
Normal Open.
