ABB DSTXW110 57160001-AAP INPUT BOARD UNMP
Introduction to ABB DSTXW110 57160001-AAP Input Board (INPUT BOARD UNMP)
ABB DSTXW110 57160001-AAP is a DC Speed Regulation Input Board in the ABB AC800M/Advant Master distributed control system, belonging to the S800 I/O architecture terminal control unit. The module itself does not directly drive the actuator, but serves as a signal bridge between the DC motor speed control system and the DCS main controller. It specifically receives voltage, current feedback signals, and operating status signals from the DC speed controller, processes them, and uploads them to the main controller to achieve closed-loop monitoring and protection of the DC motor speed.
core positioning
This module is the “signal acquisition center” in the DC speed regulation system. The front-end outputs analog and digital signals such as voltage, current, speed, and faults of the motor through a DC speed regulator (such as ACS800 series driver or dedicated DC speed regulation device), which is connected to DSTXW110 through cables. DSTXW110 collects, filters, and scales these signals, converts them into an internal data format recognizable by the DCS system, and uploads them to the main controller (such as PM802F, DSPC170, etc. CPU). At the same time, it also receives control signals such as speed setting and start stop instructions issued by the main controller, and sends them back to the DC speed regulator, forming a complete speed control loop.
UNMP “(Unmounted) means that the board is supplied in bare board form and does not come with a termination unit. Users need to select TU810, TU812, TU814, TU818, TU830, TU833, TU838, TU850 and other termination units according to the on-site signal type to complete the wiring.

Main functional features
ABB DSTXW110 57160001-AAP INPUT BOARD UNMP
DC speed control signal acquisition: specially designed for DC motor speed control scenarios, it can simultaneously collect multiple analog signals such as motor armature voltage, armature current, excitation current, speed feedback, as well as digital signals such as governor operation status and fault alarm. The channel configuration is optimized for speed control circuit, which is different from general digital input boards.
Wide range speed adjustment support: When combined with a DC speed controller, it can achieve smooth adjustment from low speed to high speed. The board provides signal scale conversion function internally, supporting direct mapping of 0-10V or 4-20mA signals to engineering values (such as 0-1500 RPM), reducing the computational burden on the main controller side.
Multiple control mode adaptation: Supports signal access for multiple speed control modes such as speed control and torque control, and can be flexibly adapted according to the configuration of the on-site DC speed controller to meet the requirements of different processes for motor operation.
Electrical isolation: An electrical isolation of ≥ 1500V is achieved between the input channel and the communication bus, effectively suppressing the electromagnetic interference generated by high-power switching devices of the DC speed controller on the DCS system and improving system safety.
Circuit monitoring and fault diagnosis: supports the detection of input signal open circuits, short circuits, communication interruptions, power outages, and other abnormalities. Fault information is reported by the basic unit to the main controller, and diagnostic data can be viewed through system software to quickly locate whether it is a problem on the governor side or the board card side.
Status indication: Equipped with operation indicator lights, channel status indicator lights, and power indicator lights, it can quickly determine the working status of modules and channels on site without the need for additional diagnostic tools.
Parameterized configuration: Supports online configuration of I/O parameters through ABB dedicated industrial control software, including channel filtering time, signal type, engineering quantity range, etc. The configuration takes effect in real time, reducing downtime for debugging.
Hot plug support: Supports online hot plug replacement, maintenance can be completed without cutting off the power supply of the I/O station system, reducing the risk of downtime.
Start self check: Automatically check the electrical ID of the module when powered on, and do not enter the running state when it does not match the configuration, to prevent control abnormalities caused by mismatches.
Comparison with products in the same series
DSTX170 (57160001-ADK) is a universal connection unit that focuses on multi protocol communication and universal I/O scheduling, and is not optimized for DC speed regulation. The core positioning of DSTXW110 is a “DC speed control dedicated input board”, which is designed around the DC motor speed control circuit in terms of signal type, channel configuration, scale conversion, etc. It is a dedicated alternative solution for general units such as DSTX170 in DC speed control scenarios. DSDI110A (5716001-AAA) is a 32 channel pure digital input module without analog input channels, which is not suitable for speed regulation scenarios that require simultaneous acquisition of voltage and current analog quantities. DSTS104/DSSTS105/DSTS106 are digital fixture modules that focus on on-site switch quantity acquisition and driving, and have completely different functional positioning from the speed control input board. DSTXW110 is irreplaceable in scenarios where DC speed regulator signals need to be connected to DCS for closed-loop monitoring.
Typical application scenarios
Power industry: Signal acquisition and speed monitoring of DC motor speed control system for generator set feed pumps and fans.
Metallurgical industry: Voltage and current feedback and status monitoring of DC transmission devices for rolling mills and continuous casting machines.
Mining industry: speed regulation closed-loop control of DC motors for elevators and belt conveyors.
Paper industry: speed feedback and protection signal connection of paper machine drive DC motor.
