Features:
- Digital Output Interface Between Control Systems and Industrial Field Devices
- Provides 16-Channel Opto-Isolated Switching with Wide Voltage Range Support
- Operates in Conjunction with ABB Distributed Control Systems and PLC Platforms
The ABB DSDO120 57160001-AK Digital Output Unit serves as a reliable digital output interface in industrial automation racks, providing isolated DC switching signals to multiple field devices within the system. It continuously drives output loads across 16 independent channels, each supporting 24-48 V DC at up to 1 A per channel, and distributes these control signals through the rack backplane to support steady state operation of connected actuators and indicators. Reliable signal isolation is standard with the DSDO120 57160001-AK, with its built-in opto-isolation technology ensuring effective electrical separation between control circuits and field equipment to prevent ground loop interference and enhance system safety.
The DSDO120 57160001-AK provides essential digital output functions common to the entire control rack, and is a critical component of the control path, directly affecting the proper, normal operation of the overall automation system. One or more DSDO120 57160001-AK output modules may be installed per rack depending on the required channel count and I/O density. The DSDO120 57160001-AK occupies a standard slot position in the rack and integrates directly with the ABB backplane architecture.
For expanded output applications, the ABB system allows additional DSDO120 57160001-AK modules to be installed in available slots. In addition to standard single module operation, multiple DSDO120 57160001-AK units can be configured within the same rack to scale channel capacity as needed. The ABB rack configuration executes module addressing through the internal backplane circuitry specified in the system options.
The DSDO120 57160001-AK ABB Digital Output Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
