The TSX CTY 2A, TSX CTY 4A and TSX CTY 2C modules are standard format counting modules. They are used to count pulses from a sensor with a maximum frequency of 40 kHz (CTY 2A/4A) or 1 MHz (CTY 2C).
Installation of counting modules
The counting modules can be installed in all the available slots of a Premium PLC configuration.
Number of "application-specific" channels supported:
Sensors used on the channels
The sensor used on each channel can be:
-
a 2 or 3-wire proximity sensor, type PNP or NPN. When using a mechanical contact output, it is necessary to raise the channel’s immunity in order to curb the closing bounces of the contact,
-
an incremental signal encoder with 5 VDC differential outputs (encoder with RS 422/485 line transmitters),
-
an incremental signal encoder with 10-30 VDC output (Totem Pole encoder),
-
an absolute encoder with serial outputs, standard RS 485 interface (TSX CTY 2C only),
-
an absolute encoder with parallel outputs, using the TELEFAST adapter:
ABE-7CPA11 (TSX CTY 2C only).
