UK-D (01) is included in PPU “Gefest” and works under the control of basic unit UKLSiP (B) or UKLSiP (RP) and allows implementing switching on and off of power devices and also:
- Maintenance line is controlled for break and SC
- Duty personnel is informed about its fail
UK-D (01) is used for switching on/off devices of industrial and fire automation. For load commutation in UK-D (01) there are two groups of switched contacts.
UK-D (01) are connected only in the connection line (CL) of the basic unit of UKLSiP (B) and UKLSiP (RP) and the supply voltage of UKLSiP (B) and UKLSiP(RP) should be from 20,5 to 28V.
The quantity of connected commutation devices UK-D(01) in CL is defined during projecting, by reference to the joint current supply of all devices connected to CL.
Basic parameters and properties
UK-D (01) provides control of winding entirety of starting relay. UK-D forms and delivers the announcement “Fail” to control unit UK-D (B) or UKSiP (RP) during the break of relay winding. The announcement “Fail” is also formed in UCSC (B) or UKLSiP (RP) during the break or SC of CL where UK-D devices are connected.
Current consumption rate from a connection line
- In stand by conditions – not more than 8 mA
- In fail conditions –not more than 8 mA
- During the implementation of “Start” command – not more than 30 mA
Maximal current and voltage commutated by contacts of control relay:
- AC voltage 250 V, current 3 A;
- DC voltage 30 V, current 3 A.
Environmental protection rate of covering
- With top cap – IP30
- Without top cap – IP20
Sizes, not more than, - 106х42х37 mm.
Weight – not more than 0,15 kg.
UK-D (01) keeps workability in the temperature range from -30C to +55C, relative humid limit of environment – 93% (under +40C)
UK-D (01) has “Mode” that in stand by conditions illuminates in green in the “Start” mode – red mode in “Fail” mode, with bright flashes with repeating frequency 4Hz that makes the repair of the unit and its defining easier.
The example of the diagram of switching on and off of devices through UK-D (01).
During the short circuit of relay “Announc.” on the receiving-control unit CSU the device UCSC (B) forms “Start” command, UK-D (01) switches the relay on. This relay controls two groups of double-throw contacts (block-terminals 5-10-9 and 7-8-6). UK-D (01) should be installed near the sprinkled objects.
