Hardware Specifications

Backplane Integration & Deterministic Processing

The AI561 routes digitised 12-bit channel measurement data through internal backplane bus communication velocity frameworks, assuring fixed execution rates during scanning loops. Direct physical connectivity to the primary controller CPU maintains consistent deterministic signal conversions without compromising system task cycles. Module firmware flash compatibility allows immediate hardware synchronization upon insertion onto the eCo-IO base terminal assembly.

Package Contents

• 1 x ABB AI561 1TNE968902R1101 Analog Input Module

• 1 x Pluggable Terminal Connector Set

Electrical & Physical Mounting Guidelines

• DIN-Rail Assembly: Engage the top rear notch of the module onto a standard 35 mm DIN-rail and press downward until the locking spring latches firmly.

• Signal Line Isolation: Route analog signal cables separately from 230 VAC power distribution lines to minimize electromagnetic noise coupling.

• Shield Grounding: Terminate overall cable shielding directly at the cabinet earthing rail using short conductor lengths before attaching wires to pluggable terminals.

Technical FAQ

• Can input channel types be configured individually on the AI561?

  Yes, each of the 4 analog channels can be independently configured via software for voltage (U) or current (I) measurement mode.

• Is hot-swapping supported for this module during live operation?

  No, hot-swapping is not supported; system power and 24 VDC field power must be shut down before module replacement to avoid damage.

• What resolution is provided for current and voltage measurements?

  The internal analog-to-digital converter processes all configured voltage and current input channels at 12-bit resolution.

• What limits apply to the maximum installation altitude?

  The hardware is rated for continuous operation at altitudes up to 2000 m above sea level without thermal or dielectric derating.

• Does the unit feature integral channel-to-channel galvanic isolation?

  No, channels share a common ground reference; external signal isolators are required if channel-to-channel isolation is needed.

• How is field wiring connected to the AI561 unit?

  Field connections are made via removable, pluggable terminal blocks, allowing pre-wiring and rapid hardware module exchange.

• What is the ingress protection rating for this hardware module?

  The module housing is rated at IP20, requiring installation within a protective NEMA or IP54 industrial panel cabinet.

• How does backplane communication affect CPU cycle timing?

  The internal backplane bus transfers input states deterministically within the standard CPU scan interval without adding overhead.
