[DESIGN PRECAUTIONS]
• In case of the external power supply failure or the programmable controller ( PLC ) failure, set up
a safety circuit outside the PLC so that the entire system can operate safely. The mis-output
and malfunction may cause an accident.
• Use the PLC in an environment that meets the general specifications contained in this manual.
Using this PLC in an environment outside the range of the general specifications could result in
electric shock, fires, malfunctions, and damage to or deterioration of the product.
• Do not bunch the control wires with the main circuit or power wires, or install them close to each
other. They should be installed 100 mm (3.94 inch) or more from each other. Failure to do so
may result in noise that would cause malfunctions.
• At power ON/OFF, voltage or current may instantaneously be output from the output terminal of
this module.
In such case, wait until the analog output becomes stable to start controlling the external device.
[INSTALLATION PRECAUTIONS]
• Insert the tabs at the bottom of the module into the mounting holes in the base unit. If the
module is not properly installed, it may result in malfunctions, failure, or fallout.
• Do not directory touch the module's conductive parts. Doing so could cause malfunctions or
failure in the module.
