The V1-10-400 Sink Current Converter (voltage/current converter) was developed so that 1-10V controllable ECGs can also be controlled with an external control voltage of 0-10V (max. 700m cable length). It can consume an ECG sink current of up to max. 400mA.
For the number of connectable ECGs, divide the maximum current (400mA) by the current per ECG (see ECG data sheet, approx. 0.5 to 1.5mA).
Example: 1mA / ECG = 400 / 1 = Up to 400 ECGs can be controlled.
