Overview

1794-IB8 is an eight-channel 24 VDC sinking input module for distributed field I/O. Each input reports the state of a connected DC field device through the rack adapter and controller data image.

The official instructions specify a 10 to 31.2 VDC on-state range, 8 mA nominal current at 24 VDC, 4.6 kΩ nominal impedance and 20 mA Flexbus current at 5 VDC.

Confirm the terminal base, common wiring, adapter compatibility, addressing, input filter, field-device leakage and module placement before installation. The channels are not individually isolated.

Product FAQ

What field signals does 1794-IB8 monitor?

1794-IB8 is an eight-channel 24 VDC sinking input module for distributed field I/O, reporting discrete device states through a compatible terminal base and adapter.

What input range applies to 1794-IB8?

1794-IB8 accepts an on-state range of 10 to 31.2 VDC with 8 mA nominal current at 24 VDC, so field-device output characteristics must be checked.

Are the channels on 1794-IB8 individually isolated?

The eight channels on 1794-IB8 are not individually isolated, so common wiring, grounding and separation requirements must be addressed in the field design.

What bus and power limits matter for 1794-IB8?

1794-IB8 draws 20 mA from the 5 VDC Flexbus and dissipates up to 3.5 W at 31.2 VDC, requiring adapter and thermal budgets to remain adequate.

What must be verified before installing 1794-IB8?

Before installing 1794-IB8, confirm the terminal base, adapter compatibility, keying, addressing, input filtering, common wiring and leakage characteristics of the connected devices.

What details should be provided when ordering 1794-IB8?

For 1794-IB8, provide the exact catalog and series, quantity, adapter and terminal-base catalogs, field voltage, sensor type, wiring photographs and required delivery destination.
