Modicon STB distributed I/O
solution
STBEHC3020KC counter module
Presentation
Counting parts or events, grouping objects, controlling incoming and outgoing data
streams, and measuring lengths or positions, all require counting functions.
The STBEHC3020KC counter module performs these functions for a Modicon STB
automation island (controlled by a master connected to the island) with a maximum
counting frequency of 40 kHz.
The STBEHC3020KC module, with 1 counter channel, accepts typical 24 V 
sensors (proximity sensors, photoelectric sensors, incremental encoders or
mechanical contacts) as inputs (1). The module has two 24 V  0.5 A solid state
outputs.
The Advantys conguration software is used to select and congure one of the six
functions the module can perform.
Description
The STBEHC3020KC counter module comprises:
1 Two latches for locking the module on the base.
2 An LED display block indicating the various states of the module:
Standard STBEHC3020KC module Indication
Green RDY LED Module status (2)
Red FLT LED Module error (3)
Green OUT1 and OUT2 LEDs State of the 2 outputs
Green INA and INB LEDs State of the 2 counter inputs
Green RST LED State of the Reset input
Green EN LED State of the EN enable input
3 A slot for a customizable label (on the module).
4 A colour-coded module identication stripe: black.
5 A connector for STBXTS2150 18-way removable spring-type terminals (supplied
with the module).
6 A mounting base, size 3 (28.1 mm).
7 A slot for a customizable label (on the base).
To be ordered separately:
 An earthing kit, recommended for connecting the cable shielding:
8 STBXSP3000 earthing kit, comprising 2 lateral supports, 1 metal bar
(length 1 m) and 1 earthing terminal.
9 STBXSP3010 terminals for 1.5…6 mm
2
cross-section cables or STBXSP3020
terminals for 5…11 mm
2
cross-section cables.
 STBXMP7700 optional mechanical keying pin between the module and the base.
This device ensures that the module and its base are properly matched if dismantled
or replaced.
 Sheets of labels for customization: STBXMP6700.
