TOS3200
SIGNAL I/O Connector
Internal Construction
The common for the input signal circuit and output signal circuit is the same.
It is pulled up to +12 V. If the input terminal is opened, the input signal circuit will be in the
same condition as when a high level signal is applied.

Application Examples of Input Signal
Controlling the TOS3200 using a make contact
The input terminal is set to low level by using a make contact such as
a relay or switch.
Controlling the TOS3200 using a logical device
In place of a switch in the example above, a logical device such as
a transistor is used.
Construct the circuit so that at least 5 mA of collector current ic of
the transistor can flow.
