・User must provide an external power unit (Vext <= 30
VDC) to drive the output relay.
・Do not short circuit the load (such as a relay coil). This
may damage the output relay.
・Use surge absorbing devices appropriately in the relay
circuit (see the diagram above) to suppress surge
voltage from occurring. These devices are effective to
reduce noise-related problems and to extend the relay
life.
