• An emergency stop circuit and an interlock circuit should be constructed out-
side of this module. Constructing these circuits inside this module may cause a
runaway situation, system failure, or an accident due to module failure.
• A breakdown or malfunction in the output relay can lead to the output signal
remaining ON or OFF. To prevent a module malfunction, be sure to install an
external circuit or device that will monitor the signal status and guarantee sys-
tem operation safety.
• Systems using this module should be designed so that output signals which
could cause a serious accident are monitored from outside this module.
• This module is designed to be a general-purpose device for general industries,
and is neither designed nor produced to be used with equipment or systems in
potentially life-threatening situations. If you are considering using this module
for special uses, including nuclear power control devices, electric power de-
vices, aerospace equipment, medical life support equipment, or transportation
vehicles, please contact your local PRO-iO2 distributor.
• Whenever installing, dismantling, wiring and conducting maintenance or in-
spections, be sure to disconnect power to this module to prevent the possibility
of electric shock or fire.
