Information About 1771-IGD
The 1771-IGD is part of the Allen-Bradley 1771 I/O family and is designed to accept TTL-compatible digital signals. It operates with a 5V DC input supply (±0.25V) and supports input states of 2.0–5.25 VDC for ON and -0.2–0.8 VDC for OFF in positive logic mode, with selectable jumper settings to reverse logic operation. Each input requires a maximum source current of 7 mA and a sink current of 0.8 mA. The module features 16 isolated input channels, with less than 1 ms signal delay for fast response. It consumes 130 mA at 5V DC backplane current and dissipates between 0.4 W and 2.7 W. Designed with 1500V isolation and a protective 0.5 A fuse, it safeguards against surges and accidental voltage application. The module mounts in 1771 chassis types such as 1771-A1B, A2B, A3B, A3B1, and A4B or AM1/AM2, and uses the 1771-WH wiring arm for field wiring connections. Equipped with 18 LED indicators, it provides clear channel and module status monitoring.
Key Features:
- Design: 16-point TTL digital input module for PLC-5 systems.
- Logic Levels: Supports selectable positive or negative logic states via jumper setting.
- Voltage Range: Operates at 5V DC (±0.25V) with ON/OFF thresholds of 2.0–5.25 VDC and -0.2–0.8 VDC.
- Performance: Fast response with <1 ms input signal delay.
- Protection: 1500V isolation and built-in 0.5 A fuse for surge and fault protection.
- Power Requirements: Backplane draw of 130 mA at 5V DC; 0.4–2.7 W power dissipation.
- Indicators: 18 LED indicators for channel status and module activity.
- Compatibility: Installs in 1771-A1B through A4B, AM1, and AM2 chassis; uses 1771-WH wiring arm.
The 1771-IGD delivers fast, reliable, and noise-immune TTL input interfacing for Allen-Bradley PLC-5 automation systems.
