ABB DO890 Digital Output Module S800 I/O Industrial Automation
Description
ABB DO890 Digital Output Module S800 I/O is a high-performance digital output module belonging to ABB’s industrial automation control system component series. It acts as a key bridge between control systems and field actuators, receiving digital commands from PLCs or other control systems and converting them into signals that drive external execution devices.
| Specification | Value |
|---|---|
| Operating Power Supply | 24V DC, ±10% voltage tolerance |
| Output Channels | 16 digital output channels |
| Output Signal Types | Relay output or transistor output (varies by model) |
| Output Voltage Range | Relay: AC 250V or DC 30V; Transistor: DC 24V |
