Please observe the system data for CS31 bus
Ä
Chapter 1.3 “System data and CS31 bus
system data” on page 4.
For general information on the CPU, please refer to the AC500 documentation.
In addition to the CPU, the replacement devices 07KT9x-AD are based on the
modules DA501 and DA502 of the AC500 series. All I/O channels are protected
against reverse polarity, reverse supply, short circuit and continuous overvol-
tages up to 30 V DC. For further information on these modules, please refer to
the AC500 documentation.
The description of the protective functions, error indications and diagnosis
options contained in the existing documentation are no longer valid. Please
refer to the AC500 documentation (DA501-/ DA502 modules and CPU) con-
cerning this information.
1.4.1.2 Central unit 07KT98

Chapter 1.4.1.3.1.7 “Connec-
tion of the 8 configurable analog inputs” on page 32.
Caution! Electrical isolation/potential reference has changed.
● 4 individually configurable analog outputs.
Caution! Electrical isolation/potential reference has changed.
● 2 counters for counting frequencies up to 50 kHz, configurable in 10 different modes.
Caution! Each counting input requires an external resistor of 470 Ω / 1 W that is con-
nected upstream. The potential reference has changed.

– A free protocol (communication via the blocks COM_SEND and COM_REC)
● 1x serial diagnosis interface DIAG
Caution! No electrical isolation to supply voltage L+/M.
● LED LCD display to indicate operating conditions and error messages
● Fastening by screws or snapping onto top-hat rail
● Lithium battery TA521
● Various operating buttons for user input
● Comprehensive diagnosis functions
● Integrated Flash EPROM, RAM and memory for storing programs and data
● Exchangeable SD memory card MC502
