Output Speciications
Accuracy is given as ± (% of output + counts of least signiicant digit (LSD)) at 23 °C ± 5 °C, with relative humidity less than 80% R.H.
and after a warm-up period of at least ive minutes. The maximum input voltage protection is 30 VDC.

1. Loading coeficient: 0.012 mV/mA for 1.5 V output.
2. Loading coeficient: 1 µA/ V. The minimum output voltage is based on 20 mA into a 600 Ω load.
3. If the current loop has a 24-V power, a minimum output voltage of 24 V is achievable with a 20 mA current into a 1200-Ω load (applicable only in Simulation
Mode).

4. The positive or negative pulse width must be greater than 50 µs to enable adjustment of duty cycle or pulse width under different frequencies. Otherwise,
the accuracy and range will be different from the speciications deined.
5. For signal frequencies greater than 1 kHz, add an addition of 0.1% per kHz.
