| Output Type | Qty | Max Load (Resistive) | Max Load (Inductive) | Protection | |-------------|-----|---------------------|----------------------|-------------| | Relay (r6) | 6 | [e.g., 5A @ 250V AC]| [e.g., 2A] | None (external varistor) | | Transistor (t4) | 4 | [e.g., 0.5A @ 24V DC]| [e.g., 0.2A] | Short-circuit / overtemp |

The M91-t4-r6-zk1 is classified as a heavy-duty industrial drive component. Based on standard industrial coding analysis:

Primary Application: This unit is designed for use in conveyor systems, packaging machinery, and automated assembly lines requiring high torque density and precise speed control.

The M91-t4-r6-zk1 is not a dumb I/O module; it contains a programmable logic engine. The manual dedicates 30+ pages to the proprietary ladder logic environment, M91-Logic Studio.
