Designation Existing device:
07KT98
Replacement device:
07KT9x-AD
Note
Serial Interfaces COM1, COM2 as
Modbus interfaces, for
programming and test
functions as well as
freely programmable
interfaces
COM2 (programming
function, test function,
free protocol)
DIAG (diagnosis inter-
face)
The serial COM1
interface of 07KT9x is
no longer available.
The serial diagnosis
interface DIAG has a
reduced range of
functions and is not
electrically isolated
from the supply
voltage L+/M.
Parallel interface For connection to cou-
pler

Additional information
upon request.
System bus interface CS31 CS31 Caution: Terminal
"Shield" is internally
connected to FE
(functional earth).
High-speed counter Integrated, many func-
tions configurable
Integrated, many con-
figurable operating
modes
At the counting input,
an external resistor of
470 Ω / 1 W must
always be connected
upstream. For further
information on high-
speed counters,
please refer to the
AC500 documenta-
tion.
