DP-F33-SQRT_DP-F33-220V-LIN_DP-F34-LIN_DP-F34-RS232控制器OMEGA

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

The DP-F31 ratemeter/totalizer accepts 3 to 30 Vdc pulses, dry-contact closure, voltage, or milliamp inputs, 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 input 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; input 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.
