Connection of External Devices

On the backside of the device the CERTOMAT ® IS has
two Sub-D sockets for analog signal exits with 9 poles,
RS 232 interface as well as a collective alarm contact.

•
For the external registration of speeds and temperatures,
e. g. with a recorder, the CERTOMAT ® IS has analog
signal exits (0 ... 10 V).
The conditions are as follows:
•
Speed: 0 V corresponds with 0 rpm.
10 V corresponds with 400 rpm.
•
Temperature: 0 V corresponds with 0°C
10 V corresponds with 100 °C
The moving load at the voltage entries must not be
lower than 10 kΩ.
•
Current signals (0 ... 20 mA) or (4 ... 20 mA) can
optionally be made for disposal.
The moving load at the current entries must not be
higher than 500 kΩ.
•
The Sub-D socket with 9 poles "RS 232" is currently a
Sartorius AG service interface.
•
A contact without potential is made available on PIN
4/9 via a Sub-D socket "ANALOG OUT" with 9 poles. By
help of this contact, alarm situations can be reported
externally.
•
Contact loading capacity: 230 V AC, 0.5 A (Ohm load).
