TM3DQ8R / TM3DQ8RG Characteristics

Introduction

This section provides a description of the power limitation and the output characteristics of the TM3DQ8R / TM3DQ8RG expansion modules.

See also Environmental Characteristics.

DANGER
	FIRE HAZARD Use only the correct wire sizes for the maximum current capacity of the I/O channels and power supplies. For relay output (2 A) wiring, use conductors of at least 0.5 mm² (AWG 20) with a temperature rating of at least 80 °C (176 °F). For common conductors of relay output wiring (7 A), or relay output wiring greater than 2 A, use conductors of at least 1.0 mm² (AWG 16) with a temperature rating of at least 80 °C (176 °F). Failure to follow these instructions will result in death or serious injury.

For common conductors of relay output wiring (7 A), or relay output wiring greater than 2 A, use conductors of at least 1.0 mm² (AWG 16) with a temperature rating of at least 80 °C (176 °F).

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.

Power Limitation

This table describes the power limitations of the TM3DQ8R / TM3DQ8RG expansion module depending on the voltage, the type of load, and the number of operations required.

These expansion modules do not support capacitive loads.

WARNING
	RELAY OUTPUTS WELDED CLOSED Always protect relay outputs from inductive alternating current load damage using an appropriate external protective circuit or device. Do not connect relay outputs to capacitive loads. Failure to follow these instructions can result in death, serious injury, or equipment damage.
