2) Connections to a Lamp
Use a warm-up resistor R for the connected lamp in order to increase lamp’s life-time. Determine the resistor by the
following rule: when the digital output is high level, this resistor should not turn on the lamp.

2) Connections to a Relay
The mechanical relay is inductance type load. If a mechanical relay is used, a diode must be paralleled to it to by
pass the inductance voltage generated when it is switched off. See figure 3-12 for the connections. The series resistor
is used to limit current to 60mA, in order to protect the output circuit of SMC6000.

Note: 1) A diode must be paralleled to the relay to by pass inductive voltage. Connect a series resistor
between the digital output and the relay if the drive current is great than 60mA. Otherwise the digital
output will be risk of damage.
