Information About 1771-OFE1
The 1771-OFE1 is part of the Allen-Bradley 1771 I/O family, designed to interface PLC-5 controllers with analog control elements. It features four isolated differential outputs, each capable of delivering 12-bit resolution for accurate signal generation. The module converts digital values in either binary or BCD format into analog signals to drive actuators, valves, positioners, and recorders. It installs in a single slot of the 1771 I/O chassis and draws 1.5 A from the backplane at 5 VDC, eliminating the need for an external power supply. With a maximum power dissipation of 7.9 W and thermal dissipation of 26.9 BTU/hr, it is built for continuous operation in demanding environments. Diagnostic features include startup self-check, fault indication LEDs, and overload protection on each output. The 1771-OFE1 is essential in automation systems where precise control and reliable data output are required.
Key Features:
- Design: Single-slot analog output module with four isolated differential channels.
- Output Ranges: Selectable voltage outputs of ±10 VDC, 0–10 VDC, and +1 to +5 VDC.
- Resolution: 12-bit digital-to-analog conversion for precise signal control.
- Accuracy: ±0.1% of full scale with ±½ LSB (binary) or ±½ LSD (BCD).
- Performance: Converter settling time of 0.8 ms; channel update time 1.6 ms (binary) or 8 ms (BCD).
- Power Requirements: 1.5 A at 5 VDC backplane current; no external power needed.
- Diagnostics: Self-check at startup, fault indicator LEDs, and built-in overload protection.
- Compatibility: Works with Allen-Bradley PLC-5 processors in 1771 I/O chassis, supporting block transfer programming.
The 1771-OFE1 delivers the precision and reliability required for industrial automation, process control, and motion applications.
