Claims

[Scope of utility model registration request]

This is used in a system configured to output multiple output currents to corresponding external operation terminals, and includes a current source whose output can be varied externally, and a set value for the current source at the time of output. a first output setter that provides a set value during standby, a second output setter that also provides a set value during standby, and a first output setter that provides a set value during standby;
a first switch that selects one of the output setters and a second output setter and applies the output to the current source; a second switch that internally shorts the current source; and a second switch that controls on/off of the second switch. The switching circuits of each current output circuit are interconnected to exchange information with each other, and the output circuits are interconnected via a reverse current blocking diode. What is claimed is: 1. A duplex control circuit for output current, characterized in that it is configured as follows.
