6.8 Binary Input Module (NR4501/NR4502/NR4503/NR4504)

The binary input module contains some binary inputs which are used to monitor the contact
positions of the corresponding bay, and all the binary inputs are configurable through
PCS-Explorer configuration tool. Some of them are used as general purpose binary inputs, and
others are used as special purpose binary inputs. These binary inputs are all optical isolated
binary inputs.
The regular optical isolated binary inputs are used to monitor the position of the regular binary
signals; the special optical isolated binary inputs are used to monitor the position of the special
binary signals, which must be taken into account in the protection and interlock logic calculations
of the main CPU module.
There are four types of binary input modules: NR4501, NR4502, NR4503 and NR4504. The view
of the binary input module is shown in Figure 6.8-1.
A 22-pin connector is fixed on the front side of this module. The terminal definition of the
connector is described as below.
