DRT2 Features Section 1-1
â– MIL Connector Terminals/Board Terminals
In contrast to the existing Units, which could only measure I/O (OUT-IN), these
Units can also measure operating times for IN-IN and OUT-OUT combina-
tions. In addition, the trigger edge (ON to OFF or OFF to ON) can be selected
and input and output numbers can be freely combined for flexible settings.
Features of Screw-less Clamp Terminals (General-purpose Slaves)
Labor-saving Clamp
Terminal Block
For I/O wiring, a screw-less clamp terminal block is provided. Wiring is
reduced by the use of post terminals that can be easily inserted and then later
removed by simply pressing a release button.
Detection Functions
(Standard Feature, DRT2-
@D@@SLH(-1) Only)
Detection results can be read by using the Configurator or explicit messages if
the sensor short-circuit/disconnected and external load short-circuit/discon-
nected detection functions are used. The error location can be rapidly speci-
fied and restored.
Operation Time Monitor In contrast to the existing Units, which could only measure I/O (OUT-IN), these
Units can also measure operating times for IN-IN and OUT-OUT combina-
tions. In addition, the trigger edge (ON to OFF or OFF to ON) can be selected
and input and output numbers can be freely combined for flexible settings.
Features of Environment-resistive Terminals
Dust-proof and
Waterproof Construction
(IP67) for High Resistance
to Environment
The environment-resistive construction enables usage in locations subject to
oil and water splashes (IP67). An environment-resistive box is not required,
enabling greater downsizing and reducing wiring labor.
No Power Supply Wiring
for Input Devices
(Advanced Models Only)
Power for communications, internal circuits, and input devices is shared, mak-
ing wiring necessary only for the communications power supply. With stan-
dard models, a power supply must be wired to I/O devices.
Connect High-load
Devices (1.5 A Max.,
Advanced Models Only)
The rated output current is 1.5 A, allowing the direct connection of output
devices with high loads.
Operation Time Monitor
(DRT2-MD16CL(-1) and
DRT2-@D04CL Only)
The time that lapses from when the output turns ON to when the input turns
ON can be measured at high speed from the Slave (without relying on the lad-
der program). The Slave also maintains a set value for monitoring the opera-
tion time, and will provide notification the Status Area if the set time is
exceeded. The Configurator or explicit messages can be used to read the
information.
Analog Slave Features
Setting the Number of AD
Conversion Points (DRT2-
AD04 Only)
The conversion cycle when all 4 analog input points are used is 4 ms max.
The AD conversion cycle can be shortened by reducing the number of points
used (i.e., the number of AD conversion points).
Moving Average (Input
Units Only)
Analog Input Terminals and Temperature Input Terminals can calculate the
average of the past eight analog input values to produce a stable input value
even when the input value is unsteady.
Scaling Scaling allows values to be converted according to the industry unit required
by the user. It reduces the number of operations requiring ladder program-
ming in the Master CPU Unit. Scaling also supports an offset function for com-
pensating for errors in scaled values.
Peak/Bottom Hold (Input
Units Only)
The maximum (peak) and minimum (bottom) values input to Analog Input Ter-
minals and Temperature Input Terminals can be held. These values can then
