1746-OB6EI Allen Bradley

1746-OB6EI Allen Bradley

digital I/O module in the SLC 500 system. The 1746-OB6EI has 6 outputs but no inputs. This module is equipped with internal protection against short circuits and overloads current conditions. However, this module does not have any protection against reverse polarity wiring or wiring to AC power sources.

Features:

• this module does not replace circuit breakers, fuses, or other code-required wiring protection devices.
• Auto-reset function which allows the module to auto-reset and resume control of the output channel.
• During the current limit, the output channel may cool to a temperature below the thermal cut-out temperature.
• If you want the auto-reset operation to happen, you need to add an external mechanical fuse to open the circuit when the circuit is overloaded.
• has a lower heat dissipation than other members of the 1746 series.
• Its total heat dissipation is 2.9 W.
• The heat dissipation per point of this module is 0.44 W.
• The 1746-OB6EI module has an operating voltage of 10 – 30V DC (source)
• Backplane current consumption of 46mA at 5V DC and 0mA at 24V DC.
• Its continuous current per output and per module are 2A and 12A at 60°C respectively.
