#53, M2S: Isolated 4-20mA ADC
|Top Previous Next|
Function: Isolated 4-20mA ADC
Form factor: M2T
Category: Input module
Special needs: --- (isolated +/-15V power is generated internally)
Power requirements: 5V/100mA
This ADC Tibbit uses an RCV420 current loop receiver front-end and an ADC1100 16-bit analog-to-digital converter IC. To lower noise and improve resolution, this Tibbit has its own isolated power domain.
The full-scale conversion error for this Tibbit does not exceed 2%, and the effective flicker-free resolution is 15 bits.
There is one red and one yellow LED. The red LED is connected to the SCL line of the I2C interface; the yellow LED – to the SDA line.
The use of this Tibbit is illustrated by a Tibbo BASIC test project. You can find it here: https://github.com/tibbotech/CA-Test-Tibbit-53.
