Counter module STB EHC 3020
Counting parts or events, grouping objects, controlling incoming and outgoing data
streams, and measuring lengths or positions all require counting functions.
The STB EHC 3020 counter module performs these functions for an Advantys STB
automation island (controlled by a master connected to the island) with a maximum
counting frequency of 40 kHz.
The STB EHC 3020 module, with 1 counting channel, accepts as input typical
c 24 V sensors: proximity sensors, photo-electric detectors, incremental encoders
or mechanical contacts (1). As output, the module features 2 static c 24 V 0.5 A
outputs.
The Advantys configuration software is used to select one of the six functions the
module can perform.
The front panel of the STB EHC 3020 counter module features:
1 A display block with 8 display LEDs:
.
2 Place for customizing labels.
3 Color-coded module identification stripe (black).
4 A connector for an STB XTS 2150 18-pin removable spring-type connector
(must be ordered separately).
To be ordered separately:
b STB XBA 3000 base width 28.1 mm (1.10"). Includes a place for customizing
labels.
b 18-pin removable spring-type connector STB XTS 2150.
b It is advisable to use a grounding kit for connecting the cable shielding.

b Optional mechanical keying pin between module and base STB XMP 7700. This
device ensures that the module and its base are properly matched after dismantling
or replacement.
b Sheets of customizing labels: STB XMP 7600.
(1) The counting frequency is limited to 400 Hz with mechanical contacts.
(2) RDY is on permanently if the module is operational. If RDY is not lit, the PDM is not supplying
power. If RDY flashes, the module is faulty.
(3) If FLT is lit or flashing, the module has an internal error.
