Connection of External Devices

At the rear side of the device the CERTOMAT ® BS-T has
two Sub-D sockets with 9 poles for analog signal exits,
RS 232 interface, as well as a collective alarm contact.

3.4.1 Analog Exits (ANALOG OUT)

•
For the external registration of speeds and temperatures,
e. g. with a recorder, the CERTOMAT ® BS-T has analog
signal exits (0 ... 10 V).
The conditions are as follows:
•
Speed:
•
Temperature:
The moving load at the voltage entries must not be
lower than 10 kΩ.
•
Optionally current signals (0 ... 20 mA) or (4 ... 20 mA)
can be made for disposal.
The moving load at the current entries must not be
higher than 500 kΩ.

3.4.2 RS 232 Interface

•
The Sub-D socket with 9 poles "RS 232" is currently a
Sartorius AG service interface.

3.4.3 Collective alarm

•
A contact without potential is made available on PIN
4/9 via a Sub-D-Socket "ANALOG OUT". Alarm
situations can be reported externally by help of this
contact.
Contact loading capacity: 230 V AC / 0.5 A (Ohm load).
