DKTFM418B 3BHB015651P0001 Counting Module
Product Manual：
DKTFM418B (3BHB015651P0001) – ABB high-speed counting/position module
Model: DKTFM418B
Material Number: 3BHB015651P0001
Brand: ABB
Type: Intelligent high-speed counting/position interface module (non ordinary I/O card)
1、 Core positioning
Used for ABB AC450/MasterPiece 200/1/800xA/AC800M systems
Specialized in handling high-speed pulses, encoders, frequency, and position loops, sharing CPU load without losing pulses
Typical scenarios: speed, flow rate, valve position, rolling mill synchronization, positioning control
2、 Counting/Input Key Points
Channel: 4-8 high-speed differential/single ended pulse inputs
Frequency: Maximum MHz level (much higher than ordinary DI cards)
Signal source: encoder, proximity switch, flow meter pulse
Function: add/subtract count, frequency measurement, cycle measurement, position latch, event timestamp
Processing: Onboard independent MCU, hardware filtering+pulse capture, does not occupy the main CPU cycle
3、 Electrical and Environmental
Power supply: 24VDC (backplane power supply)
Temperature: 0 ° C~+55 ° C (industrial grade)
Protection: IP20, anti EMI/RFI
Installation: S400 rack backplane installation
4、 Communication and Systems
Bus: Advant Fieldbus 100/MasterBus 300
Data: Real time upload of count values, frequency, location, and diagnostic status
Diagnosis: self diagnosis+fault reporting+redundant support
5、 One sentence summary
DKTFM418B is a high-speed counting expert in ABB systems: specialized in connecting encoders/pulses, MHz level without loss of data, independent operation, stable, accurate, and fast.
