DVP-ES3 Series Operation Manual _2 input signal is below the lower limit, it only shows the minimum value. *1: If the input signal exceeds the hardware input limit, the module only shows the maximum value. If the *2: If the input signal exceeds the hardware input limit, it also exceeds the digital conversion limit and a conversion limit error appears. For example in the voltage input mode (-10 V to +10 V), when the input signal is 10.15 V, exceeding the hardware upper limit, it also exceeds the conversion upper limit. The module uses the upper limit value (32387) as the input signal and a conversion limit error appears. *3:
If an input signal exceeds the absolute range, it might damage the channel. D/A Functional specifications *1: The module is with short circuit protection, but if the duration of a short circuit is too long, it can cause circuit damage. Current output can be open circuit. 2-19 Voltage input Current input Isolation An analog circuit is isolated from a digital circuit by a digital integrated circuit/an optocoupler, but the analog channels are not isolated from one another.
