Information About 1734-IA4
The Allen-Bradley 1734-IA4 is a 120V AC discrete input module within the POINT I/O family, providing four sinking input channels for interfacing field devices such as switches, sensors, and contact outputs. Engineered for ease of installation and modular expansion, it mounts directly onto POINT I/O terminal bases, including 1734-TB, 1734-TBS, 1734-TOP, and 1734-TOPS. This module operates from an external 85–132V AC, 47–63 Hz power source, with a nominal 120V AC input. Each channel offers accurate signal detection with an ON-state range of 65–132V AC and a minimum ON-state current of 4 mA, ensuring reliable operation even in electrically noisy environments. It features built-in module, network, and individual channel status LEDs for fast diagnostics and troubleshooting.
Key Features:
- Four (4) 120V AC sinking input channels
- Compact POINT I/O modular design
- Compatible with 1734-TB, 1734-TBS, 1734-TOP, 1734-TOPS bases
- ON-state voltage detection from 65–132V AC
- Backplane current: 75 mA @ 5V DC
- Individual channel status LEDs
- Horizontal or vertical DIN-rail mounting
- 240V continuous isolation rating
- Ideal for distributed machine control applications
With a 75 mA backplane draw, compact footprint, and ability to mount horizontally or vertically, the 1734-IA4 is ideal for applications requiring distributed, high-density I/O. Its rugged design includes 240V isolation between field-side and system-side components, supporting long-term operation in industrial control environments.
