7.4- Interference suppression of the electrical
installation and protection of the power supply
In the event of inductive loads on the receiver relay outputs
(contactor coils, solenoid valves or electro-brakes), interference
suppression devices such as capacitors, RC circuits, diodes,
etc. must be placed directly at the terminals of the controlled
components using the shortest possible connections.
A draw resistor should also be used on the controller inputs.
Examples of protection system to be used :
AC
Output on AC relay
(RC circuit )
7.5- Minimum and maximum current of relay outputs
Be sure not to exceed the minimum and maximum characteristics
specifi ed in «Receiver technical characteristics» section, by
installing, if necessary, an additional load or intermediate relays
(auxiliary contacts in electrical control cabinet for power control,
for example).
