ABB PL810P 3BDH000311R0101 Substation Coupling Communication

I. Product Description
Brand: ABB 800xA / AC800M DCS, Advant OCS System
Order Number: 3BDH000311R0101 (Hardware Version R0101, General Circulation Version)
Official Model: PL810; Industry Merchants commonly call it PL810P (P = Power Link, power link, for the same hardware, no model distinction)
Module Type: S800 I/O Station Profibus DP Communication + Backplane Power Bridge Integrated Module
Installation: Standard DIN35 Rail, parallelly plugged in with AI810/DI810/DO810 and other S800 IO modules

Two Core Functions
1. Profibus DP Substation Coupling Communication
As the DP bus gateway for the S800 remote I/O station, connecting to the AC800M controller
Bus rate up to 12Mbps, standard RS485 interface, built-in terminal resistor dial switch
Supports hardware dialing of substation address, single module drives an entire rail of S800 I/O backplane for data interaction
2. Power Link Backplane Power Bridge
External connection of 24VDC, providing backplane working power for the entire rail of S800 I/O modules
Realizes multi-segment IO rail power cascading, reducing external power terminal wiring
Built-in overcurrent and short-circuit protection, automatic power cut-off for IO short circuit at the rear end, protecting all station modules

Electrical and Environmental Parameters
Power supply voltage: 24VDC (allowable 19.2~30VDC)
Maximum power consumption: 10W
Communication protocol: Profibus DP
Operating temperature: -25℃ ~ +70℃
Protection level: IP20 (only for use in the control cabinet)
Dimensions: 89 (H) × 22 (W) × 120 (D) mm
Weight: Approximately 0.34kg
Backplane bus: Unified internal IO bus of S800, fully compatible with all S800 modules

Panel Indicator Light Definitions
PWR (green): Normal 24V power supply
COM (green flashing): Normal Profibus DP communication data interaction
ERR (red constantly on): Bus failure / Backplane short circuit / Power supply abnormal

 Clarification of Model Description
The original factory nameplate only prints PL810, without PL810P silk-screening; PL810P is the market common name, referring to the PL810 with power bridge function;
You previously input PL81OP as a handwritten input error of letter O / digit 0, the correct one is PL810;
Order number 3BDH000311R0101 is uniquely corresponding to this module, there is no alternative model, the hardware of the same order number is completely interchangeable.

 Application Scenarios
Chemical, power, metallurgy, papermaking, water treatment 800xA DCS system; S800 distributed remote I/O cabinet标配 coupling power supply module.
