Description
The SDCS-CON-2 3ADT309600R1 SDCS-CON-21 3ADT220072R0012 is the core control board of ABB's classic DCS 500/600 DC drives, responsible for closed-loop control, I/O processing, and fault diagnosis. These modules typically include onboard interfaces for connecting external function blocks, with the CON-21 often used as a high-durability coated variant in DCS 600 systems.
Applications
Steel rolling mill: Used for main circuit control and speed chain synchronization of DC drive systems for large rolling mills.
Paper machinery plant: Achieves high-precision paper tension control through high-frequency encoder feedback in multi-motor distributed drive systems.
Mining hoist plant: Responsible for logic interlocking and safety protection monitoring of hoist winch systems.
Rubber and tire plant: Used for high-torque DC power speed regulation of internal mixers and extruders.
Old equipment retrofitting plant: Specialized in upgrading the control layer and replacing spare parts for older DC systems such as DCS500.
Watchdog function
The control board has an internal watchdog. The watchdog controls the running of the control board program. If the watchdog trips, it has the following effects:
Writing to FPROM is disabled.
Thyristor firing control is reset and disabled.
Digital outputs are forced low.
Programmable analogue outputs are reset to zero, 0 V.
FAQ
Q: Can SDCS-CON-21 3ADT220072R0012 replace SDCS-CON-2?
A: Usually yes, but EPROM version and jumper settings must match.
Q: What happens if +5V is abnormal on SDCS-CON-21 3ADT220072R0012?
A: Below 4.55V triggers undervoltage protection and drive shutdown.
Q: What encoder frequency does SDCS-CON-21 3ADT220072R0012 support?
A: Up to 300 kHz high-speed pulse input.
Q: Can SDCS-CON-21 3ADT220072R0012 detect 12V digital input?
A: 12V is unstable; valid range is 16–60V high level and 0–8V low level.
Q: Can SDCS-CON-21 3ADT220072R0012 operate in cold environments?
A: Yes, minimum operating temperature is -20°C.
