intelligent scr Trigger module

Specifications

Feature
Working power supply: AC220V 50Hz 5%
Working environment: ambient temperature 40; humidity 85 (without
dew); without strong magnetic field; without strong vibration.
Input signal: 4-20mA linear current (0-10mA, 0-10V, 1-5V,
please give indications when ordering goods)
Output capacity: to drive SCR (trigger pulse 3V/200mA, 50S)

 Use method:
1. Automatic output: When the common-automatic terminal is short-circuited, the
trigger output volume can be controlled through inputting 4-20mA signal from the
input signal +,- terminal.
2. Manual output: When the common-automatic terminal is short-circuited, the
trigger output volume can be controlled through the manual adjustment (1K
potentiometer).
3. Current limit: When the current limit function is used, for TCW-32 ZK Y1, the current
transformer signals in the main circuit shall be introduced to the A1-A2 terminal; for
TCW-32 ZK Y3, the current transformer signals in the three-phase main circuit shall be
respectively introduced to A1-A2, A3-A4, A5-A6 terminals. And connect with the
current limit (1K potentiometer) externally to adjust the current limit value through the
potentiometer. In order not to influence the adjustment and output of the main control
meter, when the current limit function is used, the current limit value is generally set
near the rated current of load. In addition, to reliably use the over current protection
function, it is also necessary to set the current limit value near the rated current of load.
