Information About 1756-IA16
The 1756-IA16 is part of the ControlLogix I/O family, designed for reliable AC signal interfacing. It provides 16 inputs, organized into two groups of eight, with each input channel featuring individual status indicators. The module has a maximum hardware delay of 10 ms for OFF-to-ON transitions and 8 ms for ON-to-OFF, with user-selectable filter times (1 or 2 ms for ON; 9 or 18 ms for OFF) to improve noise immunity. Input thresholds range from 5 mA at 74V AC (minimum ON current) to 13 mA at 132V AC (maximum ON current), with a maximum OFF-state current of 2.5 mA. It connects via 1756-TBNH or 1756-TBSH removable terminal blocks, simplifying installation and maintenance. The module consumes 100 mA at 5.1V DC and 2 mA at 24V DC from the backplane, with a total maximum power dissipation of 5.8 W. Designed for ControlLogix systems, it ensures stable signal acquisition while reducing false triggering in noisy environments.
Key Features:
- Design: 16-point AC input module for ControlLogix PAC systems.
- Voltage Range: Operates at 74–132V AC, 120V AC nominal, 47–63 Hz.
- Input Grouping: Two groups of 8 inputs with individual channel status LEDs.
- Performance: Hardware delays of 8–10 ms with programmable input filters for noise suppression.
- Current Ratings: ON-state current 5–13 mA; OFF-state current up to 2.5 mA.
- Power Requirements: 100 mA at 5.1V DC and 2 mA at 24V DC backplane draw.
- Connectivity: Supports removable terminal blocks 1756-TBNH and 1756-TBSH.
- Reliability: Built-in filtering and diagnostic indicators ensure robust field signal integration.
The 1756-IA16 provides reliable AC input handling and diagnostic capability for ControlLogix automation systems.
