C1 as relay/SSR/mA/Volt output or C1 (open)
and C2 (closing) for electrical control valves
A1,A2,A3 ON if an alarm is present
MAN ON if the "manual" function is switched on
TUN ON if the controller is running in the "Autotune" cycle
REM ON for serial communication

Keyboard:

3 buttons for programming and setting the
setpoint.

Entrance areas:

Setting the input signal in the software
or via keypad.
Thermocouple type K,S,R, J; reference junction: internal (from 0 °C to

Potentiometer: 1 kOhm to 6/160 kOhm

Accuracy:

Tolerance at 25 °C +/-0.2 % ± 1 digit for thermocouple input
Thermocouple input, temperature sensor and analog signal.

Measurement cycle:

programmable up to 4.1 msec (242 Hz).

User input:

Switchable via potential-free contact.
(Not possible for all sensor types with the UR484802).
Alternatively adjustable functions: Hold/freeze values, ON/OFF
for the auto-tuning function, switching from automatic to manual function,
Start of program cycles/settings, selection of
setpoint 1 to 4.

Power input (only UR484803/04):

max. 50 mA with 80 mSec.
measuring cycle, e.g. for heating current monitoring.

Sensor supply:

+12 VDC @ 50 mA

Relay output:

1 changeover relay and 1 or 2 NO contacts with
common earth, 5 A at 250 VAC. Programmable as
control output for heating/cooling or alarms.

Analog/SSR output:

Selectable via jumper. Programmable
analog output 0 VDC to 10 VDC or 0/4 mA to 20 mA with a resolution of
resolution of 4000 steps. Programmable as control output or
transmission of actual value/setpoint. SSR output 12VDC at max. 30 mA.
With the UR484802 device only optional analog output, SSR or relay output Q2.
relay output Q2.

Power supply:

24 VAC/DC to 230 VAC/DC +/-15 %, 50/60 Hz, 5.5 VA

Ambient conditions:

Operating temperature: 0 °C to +45 °C;
Relative humidity 35 % to 95 % rH, non-condensing.

Programming:

Programming and operation is menu-driven
menu-guided via the front buttons. With the programming kit, the
controller can also be programmed using Windows ™ software.
This software is compatible with Windows 7 and Windows 10.
The memory card has an internal battery. This makes it possible to
devices can be programmed without connecting the power supply
(up to 1000 programings with one battery).

Functionality:

The basic version includes a control output for two-point control
(with hysteresis) with P, PI, PD and PID behavior is included. The
output is time-proportional. In addition, a cycle control
for a control valve can be programmed.

Alarm operating modes:

They switch when the temperature exceeds or falls below
temperature or deviation; band alarm; limit value or continuous
continuous signal switching.
Standby and hysteresis programmable.
In the event of sensor breakage: Reaction as for overtemperature.

Second control output (cooling)

instead of the 2nd alarm output
programmable: With P, I, PI, PD and PID behavior. The output
is time-proportional. Switching cycle, ratio to heating,
overlap or deadband are programmable.

Data protection:

Password-protected access to setpoint, alarm values
and parameters.

Housing:

Black, impact-resistant plastic housing. The electronic insert can be pulled out to the front.
