3.1.4 Terminal X6
21. Output 1 potential free 25. NC Relay Ready
22. Output 2 potential free 26. NO Relay Ready
23. Output 3 potential free 27. Option safety relay
24. Common reference 28. Option safety relay
of the outputs
The outputs X6: 21 - X6: 24 are designed for 24 Vdc max. 50 mA load. To protect against
destruction, the outputs are secured by 50 mA PTC fuses (self-resetting) and thus short-circuit
proof. The logic of the outputs is only determined by the potential at X6:24 (+24V positive logic;
GND negative logic). The outputs are not connected to the inputs, GND or PE, the outputs are
galvanic isolated by opto-couplers. The function of the output is defined by software.
Positive logic (reference 24Vdc)
Negative logic (reference GND)
The potential free contact of the relay is connected to X6:25 and X6:26 (contact 30VDC/1A). The
relay has the same function as the output Out 1
The terminals are for optional extensions.
Option safety relay
If the option safety relay is built-in, then the make contact is on X6:27 contact and X6:28 make
contact (max. 30V /1A).
Option analog output
If the option analog output is built-in, these outputs are on the terminals X6:27 Analog 1 X6:28
Analog 2 (0-5V max. 1mA). The reference is GND on terminal X7:9.
If both options are built-in, the analog outputs are on terminals X5:31 Analog Out1 X5:32 Analog
Out2 and X5:33 Analog references.
