Voltage supply

EDSMF2133IB EN 5.0

External voltage supply

) Note!

Always use a separate power supply unit in every control cabinet and safely

separate it according to EN 61800−5−1 ("SELV"/"PELV") in the case of external

voltage supply and larger distances between the control cabinets.

External voltage supply of the communication module is required if communication via

the fieldbus is to be maintained even when the power supply of the standard device fails.

) Note!

With external voltage supply of the communication module, the active bus

terminating resistor is fed independently of the operation of the basic device.

Thus the bus system remains active even if the basic device is switched off or

fails.

Plug connector Explanation

"+" V = 24VDC (21.6 V − 0% ... 26.4 V + 0 %)

I = 120 mA

"−" Reference potential for external voltage supply

Controller External voltage supply

820X Always required

821X / 822X / 824X /

93XX / 9300 Servo PLC /

Drive PLC / ECSxS /

ECSxP / ECSxA

Only required if the mains supplying the corresponding controller is to be switched off

but communication must not be interrupted.

For these basic devices the internal voltage supply can be used.
