Auxiliary Voltage
Auxiliary voltage is 24 V DC.
The two connector terminals for the negative poles are connected with
one another inside the device, as is also the case for the two positive
poles.
In this way, supply power can be looped through to several R6000
controllers. The terminals have a maximum current carrying capacity of
10 A (also in the event of malfunction) which may not be exceeded!
The terminal block for auxiliary voltage is black.
A completely separate safety power supply system is to be used for
operation of the instrument.

Binary Inputs / Outputs (I/O)
Figure 6
Schematic Diagram, Binary Inputs / Outputs
Binary I/Os which are configured as outputs connect the auxiliary volt-
age positive pole by means of a semiconductor switch. The load (SSR,
controller input etc.) is connected to the auxiliary voltage negative pole.
Three SSRs can be connected in series for controlling 3-phase heat-
ers.
Maximum load for each individual output is 500 mA, with a limit of 3 A
per controller. All outputs are safeguarded by means of integrated,
self-restoring overload protection.
