Type
<1> Refrain from assigning functions to digital relay outputs that involve frequent switching, as doing so may shorten relay performance life.
Switching life is estimated at 200,000 times (assumes 1 A, resistive load).
<2> Terminals M3 to M6 are available only in CIMR-UB.
<3> Multi-Function Photocoupler Output is available only in CIMR-UA/UD/UT.
<4> Connect a suppression diode as shown in the Figure 3.36 when driving a reactive load such as a relay coil. Make sure the diode rating is greater
than the circuit voltage.
