2.10 Connecting Probes
• To input high voltage with the 720281 (FREQ), use an safety probe (700929, 701947,
702902).
Maximum Input Voltage and Maximum Rated Voltage to Ground of Modules
Applying a voltage exceeding the value indicated below may damage the input section. If the
frequency is above 1 kHz, damage may occur even when the voltage is below this value.
• 720211 (HS100M12)
Maximum input voltage (at a frequency of 1 kHz or less)
• In combination with an safety probe (10:1) 700929 or (100:1) 701947 or a wide
temperature range type (10:1) 702902

7 When a signal with large amplitude is applied to the L input, depending on the
number of input channels and input signal frequency, the maximum rated voltage to
ground of the L input of the safety probe and safety cable is as shown in the following
graph.
