User Manual of TV5600-B01 Series Dispensing Control System
External +24V power supply
4. Output port wiring method
The switching output of this control system is the open collector output. The common terminal is
the first pin of JC1, which is also the GND of the load power supply. When using, please connect
the pin 20 of JC1 to the +24V power supply, and the output point is low level effective.
Connect the load between +24V and the output point. The internal output circuit has relatively
complete protection measures: overcurrent protection, overvoltage protection, short circuit
protection, overheat protection, and freewheeling protection measures, but if inductive loads
such as relays are connected, connect the both ends of the relay coil to freewheeling diodes, as
shown below:

Controller output port general wiring
※Note: The recommended power supply voltage is 24V, preferably not more than 30V. The
positive and negative poles must not be reversed, and the load should not be
short-circuited, or else it will cause accidents!
