DPF-311
兩級批量控制器/速率計
DP-F30 Series
Displays Rate, Batch Total, and Grand Total
Separate K Factors for Rate and Total
12 to 24V Output
Optional 16-Point Linearization
NEMA 4X (IP65) Front-Panel Cover
產(chǎn)品描述
The DP-F31 ratemeter/totalizer accepts 3 to 30 Vdc pulses, dry-contact closure, voltage, or milliamp bs, and provides 2-stage SPDT relay outputs for batch control. The display is fully scalable for engineering units and may be toggled between batch total, rate, and grand total. The linearization option allows the user to select up to 16 different K factors over the b range for accurate indication of non-linear signals.
Other features include 12 to 24 Vdc output for powering up flowmeters; pulsed (0.1 to 9.9 s) or maintained outputs; b filtering for dry-contact closure (such as reed relays); local/remote reset; excitation for open-collector or mechanical contacts; user-programmable auto-reset of batch total (repeat cycles, 10 Hz max); security lockout to prevent unauthorized changes; factored pulse output; and analog output for rate or total (analog output not available with square root -SQRT option).
The DP-F30 series indicates rate to 5?-digits and total to 8-digits, with program and count data stored for up to 10 years if power is lost.
