JZL-213 Intermediate Relay Technical Information



JZY-200, JZB-200, JZS-200, JZK-200 (JZ-200) Series Intermediate Relays

I. Overview Purpose: This series of intermediate relays is a static type relay (hereinafter referred to as a relay), which is used in power system relay protection and various automatic control lines to increase the number of contacts and contact capacity substitution in protection and control lines. : The dimensions, terminal numbers, and terminal connections of the intermediate relay of this system are the same as those of the original electromagnetic intermediate relays DZ, DZJ, DZS-200, DZB-200, and DZ-70 series. The plug-in structure is embedded and the hole size can be seen. Figure (4) can be directly replaced and installed easily.
Second, the main technical parameters Rated voltage:
220, 110, 48, 24VDC, or VAC.
Delay range:
a, o. 02-9.99S ​​(action delay);
b, 0.04-4S (return delay).
Contact rating:
Two to eight pay points.
Contact rating:
In the voltage not exceeding 250V, the current does not exceed 2A, the disconnection capacity in the sense circuit of T=5ms DC is 50W, the disconnection capacity of the AC circuit is 250VAC, and the 5A current can be connected for a long time.
Action value:
DC voltage not more than 70% rating CCZJ-200 type not more than 80% rated return value:
The return voltage is not more than 5% of rated value Action time: NJZK-200 is less than O.OIS
NJZJ-200, NJZS200 delayed return less than 0.02S:
NJZJ-200 is less than 0.04S.
time of return:
NJZJ-200, NJZK-200, NJZS-200 is not more than 0.02S;
NJZJ-200 not more than 0.06S
Power consumption:
The DC loop is not more than 8W, and the AC loop is not more than 8VA.
Third, the use of This intermediate relay plug-in structure, the base opening and terminal connections are the same in the old fashion. Voltage start, no positive and negative polarity.
It is not necessary to add a step-down resistor during use. The delay time is set on the panel of three figures × O.OIS, such as the setting time is t = 0.02 × O.OIS = 0.02S; if the setting number is 050, t = 050 × O.OIS, such as the setting number is 999 , then t = 999 × O.OIS = 9.99S, adjustable differential O.OIS.
