Note: 1.
Terminals 3 and 7 of the AC and DC models are not internally insulated. Connect a relay with high contact reliability and insulation
(with a minimum load current of 0.3 mA) or a photocoupler with high insulation (with a residual voltage of 1 V max. and a current
leakage of 0.1 mA max.) to these terminals for external control.
2.
The terminals marked with a white rectangular box are not used. Do not use these terminals for transmission of signals.

Application Examples
High DC Voltage Measurement
When voltage exceeding the maximum voltage in the
standard range is measured (for example: more than
200 V), a divider is connected externally.
