•
Up Counter / Enable Input
•
Peak Time Counter
•
Frequency Counter 0.1 - 100 kHz
*)
•
Up/Down Counter / Signaling Outputs (DO)
•
2 Up Counter / 16 Bit / 5 kHz

Default setting
3.1
General Description
The counter in the counter module detects 24 V binary pulses and transports the
counter status to the installed bus system.
The control byte sets or resets the counter. Digital outputs “DO 1” and “DO 2” can
also be set using the control byte.
The outputs are short-circuit-protected.
Four green LEDs indicate the status of the inputs “U/D” and “CLOCK” and the
digital outputs “DO 1” and “DO 2.”
The field voltage and the system voltage are electrically isolated from each other.
With consideration of the power jumper contacts, the individual modules can be
arranged in any combination when configuring the fieldbus node.
An arrangement in groups within the group of potentials is not necessary.
The counters receives the 24 V voltage supply for the field level from an
upstream I/O module, from a supply module or from the fieldbus
coupler/controller via blade-formed power jumper contacts. It then provides these
potentials to subsequent I/O modules via spring-formed power jumper contacts.
Power from SELV/PELV power supply only!
All field signals and field supplies connected to this XTR I/O module
(750-404/040-003) must be powered from SELV/PELV power supply(s)!
