<1> Do not assign functions to digital relay outputs that involve frequent switching. This may shorten relay performance life. Switching life is estimated
at 200,000 times (assumes 1 A, resistive load).
<2> Connect a suppression diode as shown in Figure i.14 when driving a reactive load such as a relay coil. Ensure the diode rating is greater than the
circuit voltage.
<3> When set for sourcing. +5 V/1.5 kΩ or higher, +8 V/3.5 kΩ or higher, +10 V/10 kΩ or higher.
<4> When set for sinking, the external power supply should be +12 Vdc, ±5% with 16 mA or less.
