Trip and Target Logic
Directional Comparison Blocking Logic
Output contact OUT106 drives a communications equipment transmitter input
in a two-terminal line application (see Figure 5.15).
In a three-terminal line scheme, another output contact (e.g., OUT107) is set the
same as OUT105 (see Figure 5.16):
OUT107 = STOP
BTX—Block Trip Extension
The received block trip input (e.g., BT = IN104) is routed through a dropout
timer (BTXD) in the DCB logic in Figure 5.14. The timer output (BTX) is
routed to the trip logic in Figure 5.1.
