3.1.4.4 IO5 and IO6 Modules
The IO5 and IO6 modules are used to increase the number of binary inputs and outputs.
The IO5 module incorporates 10 photo-coupler circuits (BI) for binary inputs and 10 auxiliary
relays (BO) for binary outputs. The IO6 module incorporates 7 photo-coupler circuits (BI) for
binary inputs and 6 auxiliary relays (BO) for binary outputs. All auxiliary relays each have one
normally open contact.
