Bimba Digital Panel Meter

DPM Specifications

1. DISPLAY: 5 digit, 0.56" red LED, (-19999 to 99999)

2. POWER: 85 to 250 VAC, 50/60 Hz, 15 VA

Isolation: 2300 Vrms for 1 min. to all inputs and outputs.

3. ANNUNCIATORS:

MAX - max readout selected

MIN - min. readout selected

TOT - totalizer readout selected, flashes when total overflows

SP1 - setpoint alarm 1 is active

SP2 - setpoint alarm 2 is active

SP3 - setpoint alarm 3 is active

SP4 - setpoint alarm 4 is active

Units Label - software controlled units label backlight

4. KEYPAD: 3 programmable function keys, 5 keys total

5. A/D CONVERTER: 16 bit resolution

6. UPDATE RATES:

A/D conversion rate: 20/readings sec

Step response: 200 msec. max. to within 99% of final read-

out value (digital filter and internal zero correction disabled)

700 msec. max. (digital filter disabled, internal zero correction

enabled).

The meter periodically (every 12 seconds) imposes a 500

msec delay to compensate for internal zero drift. If the delay

affects applications where step response is critical, it can be

defeated. Set the display update to 20/sec to disable. In this

case, add a zero error of 0.1% FS over the 0 to 50°C range.

Display update rate: 1 to 20 updates/sec

Setpoint output on/off delay time: 0 to 3275 sec

Analog output update rate: 0 to 10 sec

Max./Min. capture delay time: 0 to 3275 sec

7. RANGE OVERLOAD RESPONSE:

Display flashes [OLOL] at approximately 105% above range

Display flashes [ULUL] at approximately -5% below range

8. DPM PFC INPUT:

* After 20 minute warm-up. Accuracy is specified in two ways:

Accuracy over an 18 to 28°C and 10 to 75% RH environment;

and accuracy over a 0 to 50°C and 0 to 85%RH (non-condensing

environment). Accuracy over the 0 to 50°C range includes the

temperature coefficient effect of the meter.

9. EXCITATION POWER:

9V ±4% initial value regulated, 130 mA max.

10. LOW FREQUENCY NOISE REJECTION:

Normal Mode: > 60 dB @ 50 or 60 Hz ±1%, digital filter off

Common Mode: > 100 dB, DC to 120 Hz

11. USER INPUTS (Logic Level): Three software defined user

inputs, jumper selectable for sink/source logic

Max. Continuous Input: 30 VDC

Isolation To Sensor & User Input Commons: 500 Vrms for

1 min.

Working Voltage: 50 V

Not Isolated from all other commons.

Accuracy: 0.17% of FS (18 to 28˚C); 0.4% of FS (0 to 50˚C)
