A protective diode ensures that the poles of the supply voltage from the power supply of the PLC can
not be swapped.
The outputs are floating when low - pull down resistor required.
Input Signals IO interface
Nominal voltage:
12 – 24 V
Absolute maximum voltage:
voltages greater than 40 V can destroy the inputs
Type:
Circuit GND directly connected
Input current:
1 mA @ 24V
Threshold value:
10 V
Internal signal delay:
No delay for direct IO access
The PLC-compatible inputs (24-V level, the positive signal is connected) include input protection
circuits. A minimum voltage of 10V is required to reliably sense a logic high signal.
Output Signals IO Interface
Operating voltage:
external source 12 – 24 V
Absolute maximum voltage:
voltages greater than 40 V can destroy the outputs
Type:
Circuit GND directly connected
Switching voltage:
positive switching (PNP)
Current:
max. 400 mA per output
Absolute maximum current:
total currents greater than 1000 mA can destroy plugs and
cables
Always consider the total sum of all output currents
Switching power:
max. 9.6 W (24 V * 400 mA) per output
Reverse voltage protection
yes, for external voltage
Protection against inductive
loads:
yes
Resistance when switched on:
0.2 - 0.8 Ohm
Short circuit protection:
full protection
The PLC outputs feature a highly integrated MOSFET, high-side switch with built-in protection. It is
possible to switch inductive or capacitive loads. The protective feature of the outputs will produce
pulses on the outputs, if the limiting values are exceeded.
Output drivers feature short circuit end thermal overload protection
