When using TM3DM8R / TM3DM8RG:
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.
At 40 °C (104 °F), all inputs and outputs can be turned on simultaneously at 28.8 Vdc.
This table describes the power limitation of the TM3DM8R / TM3DM8RG expansion module depending on the voltage, the type of load, and the number of operations required.
These expansion modules do not support capacitive loads.

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