minimum level of the type 3 to the type as shown in Table 6.

This combination allows the surge voltage to be applied from each input to other inputs, the

ground and the supply contacts in differential or common modes (see Figure 12).

±1000 V surge voltage (see Figure 12).

Finally, an external output capacitor may be placed in parallel with the opto-coupler diode to

filter the transient disturbances injected in the inputs of the module and secure the immunity

of the opto-coupler itself.
