The signal from the analogue input device is converted to digital, and displayed in
decimal and hexadecimal. These hexadecimal and decimal values are also outputted to
the analogue output device.
A speed at which data is sent and received in fieldbus etc. It depends on an equipment
(PLC etc.) at high side and is indicated by bps (bit per second).
The current necessary to operate each unit.
A metal rail conforming with DIN (German) standard.
The side connected to the end plate when the product is connected to a manifold.
Abbreviation of international (ingress) protection. A standard related to the protection
from external objects (hands, steel ball, steel wire, dust, water, etc.) applied to the
product.
Abbreviation of functional earth.
The protocol that uses digital communication to exchange signals between field
equipment (instruments and actuators) running on site and a PLC.
Abbreviation of handheld terminal.
It is possible to monitor the input/output data and diagnostic data and set parameters.
Idle refers to the SI unit operation mode, which is either in the default, pre-operational or
safe operational modes. For details, Refer to manuals of each PLC maker.
A form consisting of multiple components. A form made by combining multiple
components
Takes the sensor output that uses the NPN transistor to the signal output line.
The output type that uses an NPN transistor to operate output device. It is also known
as a positive common type since a positive potential is applied to the power supply line.
The number of points that can receive information from input device (sensor, switch,
etc.).
The number of points that can operate output device (solenoid valve, light, motor, etc.)
A diagnosis function to detect if the input or output device wiring is disconnected.
Abbreviation of programmable logic controller. A digital computer used for automation of
electromechanical processes.
Takes the sensor output that uses the PNP transistor to the signal output part.
The output type that uses a PNP transistor to operate output device. It is also known as
a negative common type since a negative potential is applied to the power supply line.
A diagnosis function to detect an over current due to the short circuit of the output and/or
power supply positive line with respect to the GND line.
A function to protect the internal circuit from being broken by an over current due to the
short circuit of the output and/or power supply positive line with respect to the GND line.
Abbreviation of serial interface unit. A unit connected to a PLC to communicate input and
output data.
The side connected to the solenoid valve when the product is connected to a manifold.
