Multi-mode High-speed Pulse Input: Support AB-phase quadrature encoder, single-phase unidirectional, bidirectional up/down count; max counting frequency 1MHz, 32-bit non-overflow counter storage。
Optical Isolation Input Circuit: Every pulse channel equipped optocoupler isolation (500VAC channel isolation), suppress on-site EMI interference to avoid pulse missing & count deviation。
Backplane Bus Communication: Direct plug into Advant standard I/O rack, communicate with AC410/AC450 via system backplane bus, no extra external communication wiring needed。
Channel LED Diagnostic Indicator: Independent LED status lamp for power, bus link and each pulse channel, quick fault locating without extra testing instrument。
Built-in Multi-protection Circuit: Overvoltage, reverse polarity and short-circuit protection for field wiring, prevent wrong wiring burnout of module internal core circuit。
Hot-swap Supported: Live plug replacement without rack power shutdown, DCS auto-identification after installation without program download。

As special-purpose counting spare of retired ABB Advant OCS DCS system, DSDP160 57160001-KG fixes typical site faults: DCS flow totalizer drifting/abnormal jumping, turbine rotating speed no real-time reading, equipment displacement positioning error out of tolerance, encoder normal but DCS no pulse acquisition caused by board component aging, isolation circuit breakdown or counter chip failure. Fully consistent with original installation dimension, backplane pin definition and system communication protocol, direct swap replacement without modifying DCS control program, field encoder wiring layout, drastically shorten plant shutdown maintenance duration during unexpected breakdown.
