Information About 1771-ODD
The 1771-ODD belongs to the earlier PLC-5 output module family and offers isolated 120 V AC outputs for robust field device control. Designed for the 1771 I/O chassis, it supports ½, 1, and 2-slot addressing and includes 16 output image bits mapped directly to the PLC data table. The module incorporates optical isolation and filtering to reduce noise, while the built-in surge suppression protects against AC-line transients. Front-panel indicators provide clear diagnostic information, including 16 output status LEDs and 16 blown-fuse indicators. Compatible with the 1771-WN wiring arm, it allows module replacement without rewiring and installs with keyed positions for correct chassis placement.
Key Features:
- 16 isolated AC outputs: Designed for controlling 120 V AC field devices.
- Wide operating voltage range: Supports 85–138 V AC input.
- Surge suppression: Protects against high-voltage transients and electrical noise.
- High current capability: Up to 2 A per output and 8 A per module.
- Front-panel diagnostics: Status LEDs for outputs and blown-fuse indicators.
- Optical coupling: Reduces noise and improves signal integrity.
- Rack-mounted design: Fits in 1771 I/O chassis with keyed connector alignment.
- Supports multiple addressing modes: ½, 1, and 2-slot addressing for flexible configuration.
The 1771-ODD delivers the reliability and precision required for AC output control in legacy PLC-5 automation systems.
