F650 units can hold two different options for F module:
Option 1: Board with 16 inputs and 8 outputs.
Option 2: Board with 8 digital inputs, 4 circuit supervision outputs, 6 conventional outputs, and two cur-
rent sensing outputs
Each model has a different wiring diagram, both wiring diagrams can be seen in chapter 2 in this manual.
The wiring diagram for models with option 1 has the internal code (189C4216H3)
The wiring diagram for models with option 2 has the internal code (189C4216H2).

The Option 2 I/O board includes two groups of 4 inputs with one common, in terminals F9 to F10. It also
includes 6 auxiliary outputs, in terminals F19 to F30 with normally open contacts and two current sensing
(latching) outputs (F31-F33 and F34-F36).
Besides, there are 2 groups of inputs for trip circuit supervision. The first group includes two isolated digital
inputs, terminals F1-F2 and F3-F4. The second group, symmetrical and identical to the first, is formed by
isolated voltage inputs F15-F16 and F17-F18.
Using voltage detectors and current sensing, it is possible to implement several trip or close circuit supervision
schemes, as well as protection of the unit output contact.
In order to implement these schemes, it is not necessary to perform any setting in the unit. Internal
functions are always operative. The detailed description of trip circuit supervision is included in chap-
3-10
