SlotGroup 3 | 2 multi-function digital outputs (24 V DC, 0.5 A, PWM)

Two fast digital outputs are available. The output circuit is optimized for fast signal output, so these can be used either as a pulse width modulated 24 V square wave signal (PWM signal) or a digital output signal. The configuration is carried out via SlotGroup 3.

Technical data	Push-pull mode
Switching times	T_ON: 750 ns typ. T_OFF: 500 ns typ.
Output current per channel	0.5 A
Load type	Ohmic, inductive, lamp load

Power supply

Dimension the power supply of the terminal according to the power requirements of the connected actuators.
Select power supply cables, power supplies and actuator cables of appropriate length.

Switching behavior of the outputs

If the output is configured as a PWM signal, it is possible to switch the output to a tristate state. The output is then actively switched to 24 V and high-resistance. The high-resistance tristate state ensures that the respective output behaves as if it was not connected and does not affect the outputs of other outputs/devices connected to it. The associated output takes on the same output voltage as the other active devices.

Notes on the switching behavior of the outputs

With inductive load:
The switching behavior of the output with inductive loads deviates from the specified switching times due to the inductance of the selected load.
When switching via a PLC variable:
If the output is switched via a PLC variable, the delays caused by the PLC cycle time must also be taken into account in addition to the T_ON/T_OFF.
In tristate mode
Internal circuit causes a leakage current in tristate mode, which results in a voltage of approx. 5 V.
If the low-level of the output is to reach approximately 0 V, an external load of approx. 47 ohms must be connected to ground.
