The PRO-iO2 module conforms to the following standards:
UL508 Electrical Control System for Industry
CAN/CSA-C22.2, No.142-M1987 (c-UL listed) Electrical Control System for Industry
<Notes>
Note the following when applying for UL recognition for equipment in which
the PRO-iO2 module is installed.
The PRO-iO2 module is designed to be used only when installed in other
equipment.
If the module is installed in an area with no air conditioning system, be
sure to install it in a vertical panel using a DIN rail or mounting holes.
Also, be sure the module is installed so it is at least 100 mm away from
any adjacent structures or devices. If these requirements are not met, the
heat generated by the module’s internal components may cause the module
to fail to meet UL standard requirements.
The power supply connected to the module must be a UL/c-UL approved
Class 2 power supply module or Class 2 transformer
*1
.
When a PRO-iO2 module under load is operated with a single power sup-
ply, the amount of current consumption and full-load current of the I/O
modules must be within the rated load of a Class 2 power supply module
or a Class 2 power supply transformer.
Be aware that the number of points which can be turned ON simulta-
neously may be limited, depending on the amount of load and the load
current value.
*1 Class 2 power supplies and Class 2 transformers should not exceed an output of 30V, and
at 8A or less, should not exceed 100VA. (National Electrical Code)
