AZI-2502
ABB AC 800M Series 8-Channel Digital Output Module (Model: DO810; Part Number: 3BSE008510R1)
(Model & Part Number Interpretation:
- DO810 (Model):
- DO: Abbreviation for “Digital Output,” clearly indicating the module’s core function of transmitting discrete control signals to field actuators.
- 810: Hardware configuration code; “8” specifies 8 independent output channels (optimized for medium-scale discrete control), and “10” denotes standard 24 V DC signal level (compatible with most industrial actuators like solenoids and relays).
- 3BSE008510R1 (Part Number):
- 3BSE: ABB’s standard part prefix for automation components, confirming compatibility with the AC 800M Distributed Control System (DCS)—ABB’s flagship platform for process automation.
- 008510R1: Revision and compliance identifier; “008510” is the base hardware code, and “R1” indicates Revision 1 (enhanced short-circuit protection and electromagnetic compatibility [EMC] performance compared to earlier versions).
- Core Positioning: The “standard digital output unit for AC 800M DCS,” designed to reliably drive low-power industrial actuators, forming a critical link between the DCS controller and field equipment in process industries. )
2. Product Description
The DO810 3BSE008510R1 is a dedicated 8-channel digital output module developed by ABB for the AC 800M DCS, a leading platform for process control in chemical, power generation, water/wastewater, and oil & gas industries. It integrates reliable output switching, channel-level protection, wide environmental tolerance, and seamless DCS integration to address three key challenges of discrete control in industrial environments:
- Stable Actuator Driving: Supports 24 V DC sourcing (PNP) output, with a maximum continuous current of 0.5 A per channel and peak current of 2 A (100 ms pulse). This enables direct control of low-power field devices such as solenoid valves (e.g., ABB V230 series), indicator lights (e.g., ABB 855T), and small relays (e.g., ABB 700-HA). The module uses field-effect transistor (FET) switching technology, delivering a response time of ≤1 ms—critical for time-sensitive operations like emergency valve shutdowns in chemical reactors.
