Indexes of situation RPN (crossed - coil instruments)
In MNPP "AHTPAKC" are developed and are issued one - and two - digit digital indexes of position of the RPN drive unitary enterprise 2 (crossed - coil instruments), unitary enterprise 21, unitary enterprise 22, unitary enterprise 23, unitary enterprise 24, unitary enterprise 25, unitary enterprise 30, unitary enterprise 31 and unitary enterprise 32. Devices are intended for indication of situation RPN in drives of domestic and import production, and also for data transmission about position of the drive in a digital form for the ACS systems.
At the moment the company releases the wide range of crossed - coil instruments allowing to pick up the necessary device to any drives used in the territory of Russia and the CIS.
Indexes unitary enterprise 2kh, unitary enterprise 3kh, unitary enterprise 4kh have the two - digit indicator and depending on modification of the index work together with the RPN drives using contact, resistive, current, code or contactless sensors of an angle of rotation of the drive.
Indexes unitary enterprise 22, unitary enterprise 24, unitary enterprise 25 - Bl, unitary enterprise 31 - Bl and unitary enterprise 32 - Bl allow to establish situation RPN ban steps. At achievement by the drive of the forbidden steps on the front panel of the device the light - emitting diode of red color lights up, and for the weekend plugs unitary enterprise 22 is given a signal of management of the RP25 relay for blocking of further operation of the drive.
All indexes, except unitary enterprise 1, have a possibility of factory control for any number of provisions of the drive (to 99). Unitary enterprise 1 is always configured to 9 provisions. Indexes unitary enterprise 23, unitary enterprise 24i unitary enterprise 25 can be connected to any drives with resistive sensors (for example, MZ - 2, MZ - 4, ED - S, MR). In coordination with the customer change of quantity of steps and resistance between them is possible.
Indexes unitary enterprise 31 and unitary enterprise 32 are developed for work with the drives using the selsyn sensor, they are connected directly to regular the selsyn sensor of the BD404 or BD1404 drive.
All indexes of situation have a digital output for information transfer about situation RPN on the RS - 232 and/or RS - 485 interface, the MODBUS - ASCII or MODBUS - RU protocol, with a speed up to 115200 Baud. In modification of indexes unitary enterprise 21, unitary enterprise 23, unitary enterprise 24, unitary enterprise 25, unitary enterprise 31, unitary enterprise 32 installation of an additional analog output 0 - 5 ma, 0 - 20 ma or 4 - 20 ma is also possible (a current loop). The measured value of the current step of switching of RPN is brought to the LED indicator with a brightness of luminescence of 10 000 MCD that gives the chance to the dispatcher from the workplace with guarantee to read out indications at any lighting. In indexes unitary enterprise 23, unitary enterprise 24, unitary enterprise 25, unitary enterprise 31, unitary enterprise 32 is a possibility of compensation of connecting wires, and also the control mode on the switched - on transformer standing in the fixed situation on one step.
Crossed - coil instruments are issued in panel board cases of various size for cutting openings of 138х138 mm, 91х91 mm, 110x110 mm, 138х67 mm, 44х91 mm that considerably facilitates installation of indexes in the ShchU panel, and also in the wall case of 120х120 mm for installation directly in the drive. Production of devices in cases of other sizes at the request of the customer is possible.
