How to Wire the Digital Outputs of the Ace PLC ?<\/h1>\n

About outputs of the Ace PLCs<\/h2>\n

Ace digital outputs are Sinking\/NPN transistor outputs\"\"<\/h3>\n

Which means that they provide the ground connection turn on a load. When switched on under program control, they complete the circuit to turn on any connected DC device up to 30VDC and 300mA.<\/p>\n

<\/div>\n

All loads connected to a digital output port should be connected to the same DC supply. The load power supply ground must be connected to the ground (next to signal 1) of the output port.<\/p>\n

How does outputs work ?<\/h2>\n

Each output is connected, through a 33K ohm resistor to the VO terminal pin (next to output 6). This acts as a weak pull up. When the output is off (logic state 0), the output will be pulled up to the voltage at the\u00a0VO\u00a0terminal.<\/p>\n

If no power supply connection is made to the VO terminal, the voltage at the VO terminal will come through a 10 ohm resistor and an isolation diode, resulting in a voltage approximately 0.7V below the 5V supply to the PLC. This is enough to allow the PLC outputs to directly interface TTL circuits.<\/p>\n

If voltage is connected from an external source to the VO terminal, inactive outputs will pull up to the external source voltage.<\/p>\n

If AC power, or higher power DC needs to be switched, the Ace\u2019s digital output ports can be connected to a Relay Terminal Block module, through a short standard cable, supplied with the module. With a Relay module, up to 250VAC and 5 Amps can be switched under program control. The cable diagram connection to the PLC digital output port pluggable connector is illustrated in the Relay Terminal Block module documentation.<\/p>\n<\/td>\n

You can add our\u00a0Optocoupled Sourcing Transistor Board TBTN06-35H<\/strong> (see our Shop page)<\/p>\n

Or… Add a pullup resistor of 2.2 k\u03a9… But in this case the logic will be inversed.<\/p>\n

\"\"<\/p>\n

For reverse the logic of output in your program, add this program (example for outputs D and E outputs) at the beginning of your main program:<\/p>\n

Here, we reverse the logic of 12 outputs (D1..D6 and E1..E6) by additing 255 with the Xor function of the Calculator tool.<\/p>\n

You can named each “ROutBitXn” by any name you want.<\/p>\n
