Power Requirements
The modules receive power through the bus interface from the +5V dc/+24V
dc system power supply.
Table 2.1 Maximum Current Draw
General Considerations
The Compact I/O system is suitable for use in an industrial environment
when installed in accordance with these instructions. Specifically, this
equipment is intended for use in clean, dry environments (Pollution degree
2
(1)
) and to circuits not exceeding Over Voltage Category II
(2)
(IEC
60664-1).
(3)
Module 5V dc 24V dc
1769-IF4I (Series A) 145 mA 125 mA
1769-OF4CI (Series A) 145 mA 140 mA
1769-OF4VI (Series A) 145 mA 75 mA
(1)
Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that
occasionally a temporary conductivity caused by condensation shall be expected.
(2)
Over Voltage Category II is the load level section of the electrical distribution system. At this level transient
voltages are controlled and do not exceed the impulse voltage capability of the product’s insulation.
(3)
Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC)
designations.
