Analog Signal Collecting Card For Vision Measurement Machine mA
level
Introduction
WC1000 series (the typical model is UWC1810) is a 4/8 terminal
analog signal collecting card based on accurate electronic
components and advanced analog circuit technology design. It is
used for mV level analog voltage collecting or mA level analog
current signal collecting.
Features
1. 4 or 8 terminal difference, single-ended voltage signal
collecting for option, the standard input voltage range is +20mV.
2. The last terminal of the UWC1810 is for -20mA-20mA current
collecting, usually used for collecting 4-20mA sensor signal.
3. The difference between UWC1400 and UWC1800 is the S5-S8 PIN is
NULL,other function are the same (3 terminal digital input, 2
terminal digital output, 2 terminal analog voltage output). The
software readable terminal is 4 or 8.
4. RS232 or RS485 communication,32/64bit operation system
compatible. Offering API interface, Demo program source code.
5. 5V excitation voltage output, suitable for connecting to the
sensors such as difference strain bridge.
6. The resolution is up to 24bit, when the pressure sensor is
constant, the ADC data shifting is 1/30000 to 1/10000 before
digital filtering, equivalent to 15bit resolution.
7. 4/8 terminal collecting card data collecting speed is 100 times
/ sec / terminal.
8. Reading 8 terminal data in one time, the reading speed is 260
times per sec.
9. 2 terminal 0-10V analog voltage output, 12 bit resolution, 20
bit effective accuracy.
10. Low shifting of the collected data, operational directly when
plug on but no need for warming up. The factory calibrating
operation needs 5 minutes warming up.
11. API function can access multiple cards.
12. Supporting external triggered signal latch input.
13. Software is available to read the standard value of the
excitation voltage.
Software is available to read ADCG value (voltage and ADC data
correspondence).
One wire function available, reading the pressure sensor electronic
label (pressure calibration value).
Application
Application:
Used for physical value measuring and control such as pressure
sensor data collecting, or strain gauge bridge differential signal
acquisition. Used for applications which control the physical value
as flow, pressure or rpm.
