Analog output (0 - 10 V) "A1"

The analogoutputs 0 - 10 V can be allocated with various functions (see IO Setup: Analog output "A").
Connection to terminal "A" - "GND" = "Analog Out" (I
It is not permissible to connect outputs of several devices to each other!

Voltage supply for external devices (+24V, GND)

A voltage supply is integrated for external devices e.g. a sensor (max. current load see technical
data).
In case of overload or short circuit (24 V – GND), the external power supply is shut down (multi-fuse).
The device performs a "Reset" and continues operation.
•
It is not permissible to connect voltage outputs of several devices to each other!
•
It is not permissible to connect voltage outputs in the device to each other!
5.11

Digital inputs (D1, D2)

Different functions can be assigned to the digital inputs "D1"and "D2" (see IO Setup: Functional
overview of digital inputs). Activation via floating contacts, a low voltage of approx. 24 V DC is
connected.
Danger due to electric current
Never apply line voltage to the digital input!
Note the input resistance (see technical data).
5.12

Relay outputs (K1, K2)

Various functions can be allocated to the relay outputs "K1" and "K2" (see IO Setup: function and
inverting relais outputs). Max. contact rating see technical data and connection diagram.
