built-in 24 Vdc power supply for supplying on-site transducers
two-line LED digital readout with adjustable brightness:
Upper display - measured value,
Bottom display - setpoint of output 1
RS485 serial interface, galvanically isolated, MODBUS-RTU (charged extra)
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, communication, access and other configuration parameters
access to configuration parameters is protected by the user's password
methods for configuring parameters:
via membrane keyboard (IP54) located on the front panel of the device;
via RS485 or AR955 programmer 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)
