ABB IMASO01 Infi 90 Analog Output Slave Module

The ABB IMASO01, also cataloged as the IMASO01 Analog Output Slave Module, provides eight analog voltage output channels for direct signal generation within the ABB Infi 90 control system. Each channel supports 0 to 10 VDC or 0 to 5 VDC output with 12-bit resolution and 100 Hz sampling.

Hardware Specifications

Infi 90 Analog Output Signal Handling

The IMASO01 provides eight independent analog voltage outputs for control signal generation. The selectable 0 to 5 VDC and 0 to 10 VDC ranges define the electrical output span for connected field devices. A 12-bit converter provides the stated output resolution, while the specified 100 Hz sampling rate defines the module's signal update capability.

The module reports overrange, underrange, and output signal failure conditions. These diagnostic functions provide status information for identifying abnormal analog output conditions within the control system.

Field Installation Guidelines

Install the IMASO01 in the designated Infi 90 hardware location and secure the module according to the applicable rack or mounting hardware requirements. Verify connector orientation and module seating before applying system power.

Route analog output wiring separately from high-voltage power conductors and high-current switching circuits where practical. Use appropriate shielded instrumentation cable when required by the connected field device and site wiring standard. Connect cable shields according to the control system grounding specification and avoid creating unintended shield ground loops.

Before commissioning, verify the required output range for each connected device, confirm channel-to-channel wiring, and check the polarity of each analog signal. Validate output values against the receiving device before placing the control loop into service.
