Allen Bradley 1794-OA16

The Allen-Bradley 1794-OA16 is a Sixteen (16) channel digital output module. This is an AC output module that generates an output voltage range of 74-132 VAC, 47-63 Hz. This module is compatible for use with any Flex I/O communication adapter. This output module is typically used to energize AC loads such as relay coils, solenoid actuated devices, contactors, pilot lamps, and sounding devices such as horn, siren and buzzer. Other electrical loads that operate at a nominal voltage of 120VAC are compatible with this output module.

The 1794-OA16 output channels are non-isolated. This module has an output current rating of 4.0 Amperes with minimum On-state current of 5.0 mA per output and maximum On-state current of 500 mA per output channel when operated at 55 Degrees Celsius. This module has an On-state voltage drop of 1.5V at 0.5 Ampere and has a surge current rating of 7 A for 40 ms, repeatable for every 8 seconds.

The 1794-OA16 has a maximum output signal delay of ½ cycle for both OFF to ON and ON to OFF output transition. This module has a FlexBus current 80 mA @ 5V DC and maximum Power dissipation of 4.7 W @ 0.5 A. It also has a maximum thermal dissipation 16.1 BTU/hr @ 0.5 A and comes with an internal fusing. Built-in fuse is a 2.5 A, 150V AC normal blow, MQ2 fuse.

The 1794-OA16 uses ta terminal base to mount and terminate signal wires to the module. Appropriate terminal bases are 1794-TBN, 1794-TBNF, 1794-TB2, 1794-TB3, 1794-TB3S, 1794-TBKD, 1794-TBNK, 1794-TBNFK, 1794-TB3K, 1794-TB3SK.
