(b) Output circuit
Output uses non-contact polarity points. Limit the current at operation up to 60mA
(per circuit). For 24V power, either power supply unit (JZNC-JAU07 (option)) or the
externalpower supply may be used.

POINT
1. 56 output are non-contact polarity points (transistor, source driver), and limit the
current at ON up to 60mA (per circuit). When the load current of each output current
signal might exceed 60mA, install a fuse of 0.1A for each circuit in order to protect the
output IC.
2. Up to 2.5A in the entire internal circuit (including JSP board) when using a power
supply unit.
