Description
Inputs and outputs
Each device type has a universal analog input
(for RTD temperature probe, thermocouple,
current, voltage, resistance transmitter, resis-
tance/potentiometer), a digital input and a
switchable digital input/output. With the excep-
tion of type 702110, where the basic type has
one relay output (N/O contact), all remaining
types are equipped with two relay outputs (N/
O contacts). The digital inputs are provided to
connect a potential-free contact. The digital
output provides a logic signal 0/14 V.
Additional relay outputs (N/O contacts), the
logic outputs (0/14 V), PhotoMOS

and an analog output (0(2) to 10 V /
0(4) to 20 mA) are available as options.
Signal allocation via selectors
The input signals of the analog input and the
digital inputs are available for further use in the
device in so-called selectors (analog selector,
digital selector). The trigger signals for the an-
alog output and the digital outputs are also as-
signed via selectors, which allows for flexible
signal/function assignment.
Interfaces
The device is equipped with a USB device in-
terface (micro-B socket on the rear of the de-
vice) that is provided for the connection to a
PC and is only used for the setup program.
Thereby the device is powered via the USB in-
terface. As a result, no mains supply is re-
quired during the configuration.
A RS485 interface is also available as an op-
tion which is provided for communication with
a Modbus master (Modbus RTU operating
mode). The master can transmit up to two an-
alog values and two binary values to the de-
vice that are used there as external input
signals. Two analog flags and two digital flags
(binary) are also available.
Voltage supply
The device is available in two voltage supply
variants: AC 110 to 240 V or AC/
DC 20 to 30 V, each 48 to 63 Hz.
Electrical connection
The electrical connection saves time by using
practical spring-cage terminals (Push-In tech-
nology).

Controller types and structures
The device is a one-channel controller that
can be configured as a two-state controller,
three-state controller, three-step controller,
and continuous controller. Depending on the
controller type, different controller structures
can be prescribed (P, I, PD, PI, PID) using ad-
justable controller parameters. The controller
supports two switchable parameter blocks.
The controller setpoint can also be switched.
Up to four setpoint values can be entered. The
selection of the active setpoint value is con-
trolled by two binary signals.
Autotuning
Autotuning (oscillation method or step re-
sponse method) also makes it possible for the
controller to be matched to the control process
by a user who is not a control technology ex-
pert. The way the control process reacts to
changes in the actuating variable is evaluated
in the process and certain controller parame-
ters are calculated.
Ramp function
The ramp function is used for a constant
change of setpoint value up to the ramp limit
value (entered setpoint value). A rising or a
falling edge arises depending on the actual
value at the time of the ramp start. The slope
is defined via two adjustable gradients (up-
ward, downward). The ramp function is con-
trolled via binary signals (start, brake, stop).
Program controller
The controller can also be operated as a pro-
gram controller. Using a program editor, the
user can create a program for a setpoint value
and four operating contacts with up to 24 pro-
gram sections. This program is processed by
the program generator. Details such as pro-
gram start, program repeat and the type of set-
point value change (jump or ramp) are
specified by the configuration of the program
generator.
Limit value monitoring
The device is equipped with four limit value
monitoring functions, each with eight configu-
rable alarm functions. Any analog signal from
a selector is selected as the value to be moni-
tored. An absolute value or a value that de-
pends on an additional analog signal serves
as the limit value. Special functions such as
switch-on/switch-off delay, pulse function,
alarm suppression in the switch-on phase or in
case of a parameter change, alarm latch and
lock with acknowledgment are available. With
the limit value monitoring function, extensive
alarm and limit value functions can be imple-
mented.
