Digital Outputs

Overview

The Modicon M262 Logic/Motion Controller has 4 embedded fast digital outputs.

The digital outputs are connected on the front face of the controller.

DANGER
	FIRE HAZARD Use only the correct wire sizes for the maximum current capacity of the I/O channels and power supplies. Failure to follow these instructions will result in death or serious injury.

WARNING
	UNINTENDED EQUIPMENT OPERATION Do not exceed any of the rated values specified in the environmental and electrical characteristics tables. Failure to follow these instructions can result in death, serious injury, or equipment damage.

The table below describes the characteristics of the embedded digital outputs:

NOTE: Refer to Protecting Outputs from Inductive Load Damage for additional information concerning output protection.

This illustration describes the pin assignment of the connector:

This table describes the pin assignment of the embedded I/O connector:

Pin	Label	Description
6	Q0	Digital output 0
7	Q1	Digital output 1
8	Q2	Digital output 2
9	Q3	Digital output 3

This figure shows the I/O status LEDs:

LED	Color	Status	Description
0...3	Green	On	The corresponding output channel is activated
0...3	Green	Off	The corresponding output channel is deactivated

NOTE: The LEDs indicate the logic state of each output.

Electromagnetic perturbations may cause the application to operate in an unexpected manner.

WARNING
	UNINTENDED EQUIPMENT OPERATION Adapt the programmable filtering to the frequency applied at the inputs. Use shielded cables wherever specified, connected to the functional ground using the TM2XMTGB grounding bar. Use a specific 24 Vdc supply for inputs and outputs. Failure to follow these instructions can result in death, serious injury, or equipment damage.

This illustration presents the fast outputs wiring diagram:

* Use a type T fuse appropriate for the load, not to exceed 2.5 A

WARNING
	UNINTENDED EQUIPMENT OPERATION Ensure that the physical wiring respects the connections indicated in the wiring diagram. Failure to follow these instructions can result in death, serious injury, or equipment damage.
