5.3.3 24VDC input power supply - J4 connector
The J4 connector (4 poles, 90° male type M12, polarization A; manufacturer: Phoenix Contact, code 1436589)
makes available the input of the external 24V DC power supply.
The pinout of the connector is shown in the following image:
The voltages to the auxiliary power supplies must be stable and contained within the limits of the HELCON
11XX series modules (refer to the specific paragraph). If these voltages are outside the prescribed limits, the
unit may be damaged.
Check the polarity of the voltages before connecting the module; risk of damage to the unit.
The 24V power supply cables must be equipped with overcurrent protection devices. Some
types of power supply perform their own protection function.
For safety reasons, these power supplies must be supplied by a PELV power supply, with
the ground terminal connected to the ground (preferentially only at one point to avoid ground
loops).
