Did you know?
WebGas detectors / transmitters offer 4-20mA outputs, where 4 mA equates to a zero reading and 20 mA equates a full scale reading of the calibrated range. This signal is sent to a remotely located control panel. The control panel uses this signal and activates executive actions via relay contacts. Web9 dec. 2024 · Here is a schematic snippet from one of my current projects that requires 8 channels of computer-controlled 4-20 mA current output: V0 is a analog voltage that controls the current going out CURR0+ and coming back to CURR0-. In this case, 20 mA results from V0 = 3.0 V. V0 can go to 3.3 V, so there is 10% overrange capability.
