TM3DM16R Characteristics

Introduction

This section describes the general characteristics of the TM3DM16R expansion module.

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.

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.

Input De-rating

When using TM3DM16R:

X Ambient temperature (°C / °F)

Y Input voltage (V)

At an ambient temperature of 55 °C (131 °F) in the horizontal mounting direction, limit the inputs and outputs, respectively, which turn on simultaneously as indicated by the X axis.

Output De-rating

When using TM3DM16R:

X Ambient temperature (°C / °F)

Y Output load current (%)

Power Limitation

This table describes the power limitation of the TM3DM16R 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.
