The CONTROLLINO PLC has „High-Side Switch“ outputs, „Half-Bridge“ outputs (only MEGA) and potential free Relays outputs. Some of these outputs are also capable of generating PWM (Pulse Width Modulation) signals. Therefore it is possible to dim a lamp or to control the speed of a DC motor.
The digital „High-Side Switch“ outputs and „Half-Bridge“ outputs (only MEGA) are labeled with “D0 .. Dx” on the upper side of CONTROLLINO. Every of this digital screw terminal switches the supply voltage to the output and can be loaded with 2A @12V or @24V. Every of this outputs are short-circuit proof and limits the maximum output current automatically. The internal resistance when switched is about 70mΩ when using the „High-Side Switch“ outputs and about 240mΩ when using the „Half-Bridge“ outputs.
INFO: This outputs are not potential free. The load have to be connected between the output and GND. At the „Half-Bridge“ outputs you can also put the load between two outputs, to drive for example a DC motor in both directions.
WARNING: this digital outputs are not made to switch 230V.
There is possibility to parallelize some digital outputs to drive loads with the need of more current with following conditions:
– Outputs are controlled from the same processor port (possibility to set it via one instruction)
– There is no delay between control signals for parallelized outputs (shall be managed by the SW).
Possible outputs for parallelization:
MINI:
1st group: D0, D1, D2, D3
2nd group: D4, D5
3rd group: D6, D7
MAXI:
1st group: D0, D1, D3
2nd group: D2
3rd group: D4, D5, D6, D7
4th group: D8, D9, D10, D11
MEGA:
1st group: D0, D1, D3
2nd group: D2
3rd group: D4, D5, D6, D7
4th group: D8, D9, D10, D11
5th group: D12, D13, D14, D15, D16, D17, D18, D19
6th group: D20, D21, D22
7th group: D23
The PWM Outputs are marked with a dark background.
MINI: D1, D2, D5
MAXI: D0 .. D11
MEGA: D0 .. D11, D14,D15,D16
With the Relay outputs „R0 .. Rx“ an external electric circuit can we switched. The type of contact can be seen on the PLC. The maximum switching current is 6A @250V/AC or 6A @30V/DC.
INFO: This Relays outputs are potential free!
IMPORTANT! The Relays Outputs are put together into 2 block.
In one block it shall be possible to use only one type of switching circuit. That means mains, circuit 230V or DC which is not SELV (Safety Extra Low Voltage) on block 1 and SELV circuit on block 2 or vice versa. Because of safety regulations it is not possible to combine these two types of circuit in one block.
