Description
The 1771-OFE2 module integrates into the 1771 I/O system, offering four isolated differential output channels with 12-bit resolution. Each channel outputs 4–20 mA current signals, suitable for controlling actuators, drives, and other analog devices. The module ensures electrical isolation between channels and the backplane, enhancing noise immunity and system reliability. It requires a 1.4 A current draw from the 5V DC backplane supply and dissipates approximately 7.9 W of power. The module is compatible with the 1771-WC wiring arm, facilitating straightforward installation and maintenance.
Features:
- Number of Outputs: 4 isolated differential channels
- Output Signal Range: 4–20 mA
- Resolution: 12-bit
- Isolation Voltage: 1000V between channels and backplane
- Backplane Current Consumption: 1.4 A at 5V DC
- Power Dissipation: 7.9 W
- Wiring Connector: Compatible with 1771-WC wiring arm
- Calibration: Requires periodic calibration for accuracy
- Indicators: LED status indicators for module diagnostics
