microprocessor controller for temperature and other physical quantities (humidity, pressure, level, speed, etc.) converted into a standard electrical signal (0/4÷20 mA, 0÷10 V, 0÷60 mV, 0÷2.5 kΩ)
universal thermometric and analogue input with the memory for storing minimum and maximum measured values:
thermoresistance Pt100, Ni100, Pt500, Pt1000
thermocouple J, K, S, R, T, B, E, N
current 0-20 mA, 4-20 mA
voltage 0-10 V, 0-60 mV
resistance 0-2500 Ω
remote data display via RS485 (MODBUS-RTU, SLAVE)
LED display with programmable colour and brightness
BIN programmable digital input for changing operational mode of the controller:
control start/stop
manual/automatic mode for outputs
two-position switching of the set value (day/night)
keyboard lock
Display HOLD function
2 or 3 outputs of ON/OFF type (ON-OFF, control, 2- and 3-position) with the following characteristics:
output 2, 3 (auxiliary/alarm): ON-OFF with hysteresis
analogue output 0/4÷20 mA, optionally 0/2÷10 V (constant-control, retransmission)
advanced function of selecting PID parameters with fuzzy logic elements
available for binary and analogue outputs, for setting the value of the output signal in the range of 0 ÷ 100%,
alarms (of active outputs) signalled by changing display colours
built-in 24 Vdc power supply for supplying on-site transducers
RS485 serial interface, galvanically isolated, MODBUS-RTU
compensation of line resistance for resistance sensors
temperature compensation of thermocouple cold ends
programmable input, range of indications (for analogue inputs), options for adjustment, alarms, displaying, access and other configuration parameters
access to configuration parameters is protected by the user's password
methods for configuring parameters:
via membrane keyboard (IP65) located on the front panel of the device;
via RS485 or PRG port (programmer AR955) and freeware: ARsoft-LOG (Windows 7/8/10)
software and programmer allow you to view the measured value and quickly configure single or few sets of parameters previously saved in the computer for re-use, e.g. in other controllers of the same type (duplicate configuration)
high accuracy, long-term stability and immunity to interference
optionally (when ordered)
SSR control outputs
analogue output 0/2÷10 V (instead of output 0/4÷20 mA)
RS485 interface

230 Vac (85÷260 Vac) / 3 VA
24 Vac/dc (20 ÷50 Vac / 3 VA, 20 ÷ 72 V dc / 3 W)
operating temperature range: 0÷50 °C
relative humidity range: 0÷90 %RH (no condensation)
panel housing 96x48x79 mm
ingress protection rating: IP65 from the front, IP20 from the connectors
