Configured for discrete field signal acquisition in ABB Infi 90 control systems, the ABB IMDSI02 (IMDSI02 Digital Slave Input Module) provides direct electrical execution. The module accepts field input signals at 24 VDC, 125 VDC, or 120 VAC levels and transfers input status information to the Infi 90 system through isolated logic circuitry while operating from a +5 VDC backplane supply.

Product Identification

The supplied documentation identifies a fixed hardware configuration without suffix-dependent options.

Electrical and Environmental Specifications

I/O Density and Backplane Integration

The IMDSI02 exchanges discrete signal status through the ABB Infi 90 backplane architecture while operating from a low-current +5 VDC supply. The module combines sixteen digital input channels within a single hardware assembly, allowing I/O density scaling without increasing controller complexity. Signal states are transferred between field circuits and logic processing resources through isolated interface circuitry rated at 300 V RMS.

Technical FAQ

Q: What field voltage levels are supported by the IMDSI02?
A: The module accepts 24 VDC (+/- 10%), 125 VDC (+/- 10%), and 120 VAC (+/- 10%) input signals.

Q: What is the typical backplane current requirement?
A: Typical current consumption is 55 mA from the +5 VDC supply, with a maximum specified value of 79 mA.

Q: Is electrical isolation provided between field inputs and logic circuits?
A: Yes. The module provides 300 V RMS isolation between field input circuits and logic circuitry as well as input-to-input isolation.

Q: How many input channels are available?
A: The module supports sixteen discrete digital input channels.

Q: Does the module support online replacement?
A: Hot-swap capability is not specified in the available documentation. Replacement procedures should follow ABB Infi 90 maintenance instructions.
