Controller AP 21 is 4 digit, two-line programmable device for universal use. Cotroller is equiped with digital
signal processor with A/D transducer. Controller is operated with key-board placed on front panel or with
control software that is used for setting of all parameters and archiving measured values. Controller has to
be provided with communication line, variants of communication lines are in ordering code. Control software
PAP is available on www.apoelmos.cz
Controller is equipped with two-line display. Upper large display allows to set three-color function of display.
Visually interesting element is auxiliary vertical bargraph. Input section of controller is equipped with
16-bit A/D transducer with galvanic separation, which allows to connect the input connectors of resistance
sensor Pt100, Pt1000, NI1000, thermocouple J, K, E, T, R, S, B and unified current signal 0/4 - 20 mA or
voltage signal 0 - 10 V. Feedback is available for control of electric drive (resistance transmitter, current signal
4 - 20 mA or voltage signal 0 - 10 V). Controller is equipped with PID regulation. Can be regulated continuously
with the analog output or with output three positions relays. There is a version with analog output
in the ordering code of the controller. Analog output can be assigned to any input or action intervention.
Controller is equipped with two limit switches, whose outputs are relay switching contacts.
Limit switches can be set for the safety function. Then it is necessary to do the manual deactivation
after alarm switch occurs. For communication controller with the PC it possible to use any of the offered variants
of communication lines.
In ordering code is the communication line RS232 or RS485. For premium applications it is possible to use
both communication lines RS232 and RS485 simultaneously . Both communication lines work with MODBUS
protocol.
Communication enables not only setting of parameters and data archiving, but regarding the possibility of
addressing of individual controllers it can be also used for interconnection of bigger number of controlleres
and controlling of complete technological lines.
Controller features offers large possibilities of its usage, not only for PID regulation but also as signal transducers,
galvanic separation, data collection for their processing on PC, as limit switches, simple
two-state regulator, controlleres for failure signalling.
