Module
Operating Voltage Considerations
The 1753-OB16 output module has a total current capacity (16 A)
higher than the terminal block current limitation (10 A). Therefore, it
features two separate operating voltage supply connections if more
than 10 A is used by the module. The two output groups are shown
below. Each group has a current capacity of 8 A.
Safety-related Digital Outputs
The module has 16 digital outputs (DO1 to DO16) whose status is
indicated via status indicators.
Each output is rated for up to 1 A at 60 °C (140 °F) or 2 A at
40 °C (104 °F). However, each group of 8 outputs may not exceed 8 A
total. For heat dissipation, intersperse high-current and low-current
outputs so that all the high-current outputs are not next to each other.
