• If a simple load is operated
This is a method of connecting loads between the O01-O16 terminals of the TBCO1-TBCO4
terminal blocks and the GIO terminal.
Each terminal is capable of outputting a maximum of 1A, but the overall current may be limited
according to the calorific value and load.
If digital I/O power (VIO/GIO) is supplied through the internal power supply as in the factory default
setting, up to 2A of VIO current can be used. If a total current greater than 2A is required, remove
the connection between the digital I/O power supply (VIO/GIO) of the Terminal Block for Digital I/O
Power (TBPWR) and the internal power supply (VCC/GND), and an external power supply must be
connected.
