Mixed I/O Modules | Schneider AM0984MC0

The Schneider Electric AM0984MC0 is a compact mixed I/O module engineered for Modicon TSX Micro programmable logic controller systems. It provides a reliable interface for discrete automation setups by combining twelve digital inputs and eight transistor outputs into a single, space-saving unit designed for direct rack installation.

Module Architecture and Layout

Measuring 100 mm in height, 36 mm in width, and 70 mm in depth, the unit weighs approximately 0.18 kg. A single internal printed circuit board houses all input filtering and output driving circuits. All field wiring terminates securely through a single 28-pin front terminal connector, streamlining cabinet assembly and maintenance.

Electrical Ratings and I/O Performance

The twelve digital inputs accept 0 V to 30 V DC signals, drawing a typical current of 7 mA at 24 V DC with a 2 ms hardware input filter delay. Eight transistor output channels switch 0.5 A each at 24 V DC, delivering a maximum total output current of 4 A per module to drive small solenoids and indicators safely.

Installation and Protection Features

Built-in optical isolation separates the field-side circuits from the controller backplane logic, while integrated short-circuit protection prevents hardware damage during wiring faults. Field connections require 0.5 sq mm to 1.5 sq mm stranded copper wire tightened with a 3 mm flathead screwdriver, supporting operation across a 0 deg C to 55 deg C temperature range.

Frequently Asked Questions

Q: What wire size is recommended for the 28-pin front connector of the AM0984MC0? A: Use stranded copper wire with a cross-section between 0.5 sq mm and 1.5 sq mm, secured using a 3 mm flathead screwdriver.

Q: How does the module protect against electrical faults on the outputs? A: The transistor outputs feature integrated short-circuit protection, alongside optical isolation that separates field signals from the backplane logic.

Q: What is the maximum total output current capacity for this module? A: The module delivers a maximum total output current of 4 A, with each individual transistor channel rated for up to 0.5 A at 24 V DC.
