1746-OA8 Allen Bradley

1746-OA8 Allen Bradley

This module is part of discrete output modules, used to energize electrical loads that operate at an operating voltage range of 85-264 VCA with frequency of 47-63 Hz. The module’s nominal output voltages are 120VAC and 240VAC and occupies a single slot of the 1746 chassis.

Features:

• Each channel of the 1746-OA8 delivers a continuous output current of 1.0 A @ 30 °C (86 °F) or 0.50 A @ 60 °C (140 °F) 
• Maximum continuous output current per module is 8.0 A @ 30 °C (86 °F) and 4.0 A @ 60 °C (140 °F).
• Each channel has an ON signal delay of 1 ms for resistive load and maximum OFF delay signal of 11 ms for resistive load as well.
• Backplane current amounting to 185 mA @ 5VDC
• ON state output voltage drop of 1.50V @ 1.0 A.
• Minimum load current is 10 mA
