DO801 3BSE0205108R1 ABB Transistor-type digital output module AC 800M System 800 A
Product Overview
ABB DO801 is a standard 16-channel digital output module in AC 800M distributed control systems. It adopts an NPN transistor Sourcing output structure and is specifically designed to drive 24V DC loads. Such as small relays, solenoid valves, indicator lights, PLC input modules, solid-state relays (SSR), etc.
This module is equipped with short-circuit protection, overload detection and channel-level diagnostic functions. It features a compact structure and high reliability, and is widely used in industrial scenarios such as process automation, mechanical control, water treatment and packaging lines. It is an ideal choice for building an economical and efficient control system.
Core features
16-channel independent transistor output
Output type: 24V DC source (Sourcing)
Maximum load current: 0.5A per channel, total ≤ 4A per module
Conduction voltage drop: < 1.5V @ 0.5A
Comprehensive protection mechanism
Each channel is equipped with short-circuit protection and over-temperature shutdown
It can automatically recover after a short circuit (no need to replace the fuse)
Support channel-level fault diagnosis and reporting
High-reliability design
Photoelectric isolation is achieved between the channel and the backplane
Isolation voltage: ≥ 500 V AC (1 minute)
Surge resistance: ±1 kV (IEC 61000-4-5)
Technical parameters
Pneumatic system control: Drive 24 V DC solenoid valves (such as Festo, SMC series)
Signal indication: Control alarm light, status indicator light
Intermediate relay drive: Expand the contact capacity to control high-power equipment
PLC interconnection: As the interface for the AC 800M to send digital commands to other controllers
Start and stop of small motors: Indirectly controlled by solid-state relays (SSR)
Installation and Usage instructions
Hardware installation
Insert DO801 into the S800 I/O electronic rack (such as TB840A);
Connect to the CI854A or CI801 communication module via the ModuleBus cable;
Provide a 24V DC load power supply externally and connect it to the common positive terminal (L+) of the module;
One end of the load is connected to 24V +, and the other end is connected to the DO801 output terminal. The load circuit is grounded through the internal transistor of the module.
Software configuration
Create a DO801 device instance in Control Builder M;
Name each channel (such as "Valve_A_Open_CMD");
Configurable output safety status (hold/reset to zero in case of fault);
Download the configuration to the AC 800M controller.
Debugging and verification
The green LED on the front panel indicates that the module is operating normally.
If a certain channel is short-circuited, it will automatically close and report the fault.
Loop testing can be conducted by forcing the output ON/OFF through Control Builder M.
