Types of binary output circuits
(i)
There are three types of binary output circuits:
Normal type
For fail alarm
Table 5.6-7 describes the features and the symbols for the three.
No. Type
-Normally open (N/O)
-Dry contact
-Make and carry: 8A cont.
1 Normal
-Break: 0.1A at 250Vdc
-OP Time: 6ms (typical)
-Normally open (N/O)
-Dry contact
-Make and carry: 8A cont.
2 For fail alarm
-Break: 0.1A at 250Vdc
-OP Time: 8ms (typical)
Programmable binary output circuits
(ii)
Binary output circuit (BO) has a front side handler so that it can have eight arrival signals at
once. The handler combines the eight arrival signals. The combined signal passes through
delay timer and inverter; after that, it drives a BO contact. Figure 5.6-11 shows the BO circuits,
which show arrival signals, signal handlers, On/Off delay timers, inverters, and contact drivers.
PLC connection points are also provided at respective BOs.
