| Height | 110 mm |
| Depth | 100 mm |
| Weight | 0.13 kg |
Interface Types and Connection Layout
The ABB 200C-OE4 provides spring-clamp terminals for field actuator wiring. A 10-pin backplane connector supplies power and data from the PLC. The front panel carries four green LED indicators for channel status. Hence, operators can verify output activity without external tools.
Component Count and Channel Configuration
This analog output module contains one main board with four independent channels. Each channel uses a 12-bit digital-to-analog converter for precision. You will also find a voltage-to-current converter per output. An onboard microcontroller handles bus communication and diagnostics.
| Technical Feature | Description |
|---|---|
| Output Channels | 4 |
| Output Range | 4-20 mA (active or passive) |
| Resolution | 12 bits (4096 steps) |
| Load Impedance | 0 to 600 Ω per channel |
| Accuracy | ±0.1% of full scale |
Energy Storage and Power Consumption
The ABB 200C-OE4 draws 60 mA from the 5V backplane supply. It also requires 40 mA per channel from an external 24V supply. A small capacitor bank stabilizes the output current during load transients. This storage reduces signal ripple for smooth actuator control.
Output Performance and Diagnostics
The module updates all four outputs within a 1 ms cycle time. Each channel includes open-loop detection for broken field wiring. Users can configure output fallback states for safety during CPU errors. This feature prevents uncontrolled actuator movements during system faults.
