1，可接 2 線(xian)、3 線(xian)信號，每個(ge)點都帶指(zhi)示燈(deng)，狀態一(yi)目(mu)了然；

2，采用 8 組（3 位 1 組）彈(dan)簧(huang)端(duan)子（棕藍黑分別為對(dui)應負載

得 +，- 信號），接(jie)線簡單快(kuai)捷，維修和更換更加(jia)方便(bian)；

3，信號邏輯：NPN

4，每個點(dian)都帶自恢復保險。

1, can be connected to 2-line, 3-line signal, each point has an indicator

light, the status is clear;

2, the use of 8 groups (3-bit 1 group) spring terminals (brown, blue and

black respectively for the corresponding load to +, - signals), simple

and quick wiring, maintenance and replacement more convenient;

3, signal logic: NPN

4, each point with self-recovery insurance
