External Interface
8.1 External I/O Terminal
The output, START, and STOP signals regarding the status (such as the
TEST state) and decisions (such as FAIL) of the 3159 are controlled through
the external I/O terminal, located at the back of the unit. An inter-lock
terminal is provided to ensure safety. An inter-lock terminal is provided to
ensure safety.
All signal lines are insulated internally with a photocoupler. A power voltage
of 15 V (0.1 A), insulated from the internal supply, is output from the
external I/O terminal. This voltage can be used as external power. If the unit
power capacity is insufficient, add an external power supply.
