Information About 1756-IB32
The 1756-IB32 belongs to the ControlLogix family of I/O modules, designed for installation in a local or remote chassis. Each channel can handle a nominal input of 24 VDC within a voltage range of 10–31.2 VDC. The module draws 120 mA at 5.1 VDC and 2 mA at 24 VDC from the backplane, with a total backplane power consumption of 0.66 W. Maximum power dissipation is 6.2 W and thermal dissipation is 21.1 BTU/h at 60 °C. The module supports configurable input filters (0, 1, 2 ms for OFF→ON, and up to 18 ms for ON→OFF), helping reduce noise and false transitions. It also supports up to 250 mA inrush current, decaying to less than 37% in 22 ms. Diagnostic features allow detection of faults and backplane status, while channel status indicators provide quick visual feedback. The 1756-IB32 is compatible with 1756-TBCH and 1756-TBS6H removable terminal blocks for wiring. Typical applications include high-density monitoring of switches, sensors, and other 24 VDC devices in ControlLogix-based systems.
Key Features:
- Design: High-density ControlLogix digital input module.
- Channels: 32 inputs, organized into two groups of 16.
- Voltage Category: 12/24 VDC sink; operating range 10–31.2 VDC.
- Backplane Current: 120 mA @ 5.1 VDC; 2 mA @ 24 VDC.
- Power Dissipation: 6.2 W max; 21.1 BTU/h thermal dissipation.
- Response Times: OFF→ON hardware delay up to 380 µs + filter; ON→OFF delay up to 420 µs + configurable filter (0–18 ms).
- Inrush Current: 250 mA, decays to <37% within 22 ms.
- Diagnostics: Module and channel diagnostics with minor/major fault reporting.
- Wiring: Compatible with 1756-TBCH and 1756-TBS6H RTBs (sold separately).
- Mounting: Fits in any ControlLogix chassis slot.
- Applications: Suitable for large-scale digital input monitoring in manufacturing, process control, and SCADA systems.
The 1756-IB32 delivers high-density input capacity, diagnostic intelligence, and flexible integration, making it a reliable solution for ControlLogix-based automation.
