About 1771-OX
1771-OX.A-B
The Allen-Bradley 1771-OX is a power contact output module. This module has 4 N.O./N.C. output points available. Four status indicators are present with this module, with 1 indicator per output. These indicators represent the output relay coils’ state of being energized or de-energized. The 1771-OX also has a fuse that serves as protection for overload conditions. In case of overload, the output circuit will be opened.
The voltage ratings of the 1771-OX module are 0-250V AC RMS and 0-175V DC. It also has a maximum current rating of 2 A and a power rating of 200 VA. Surge currents are present with this module and these are 5.5A AC peak for 5 seconds, 6A DC for 500 seconds, and 15A DC for 500 ms. Note that the surge current is repeatable every 10 seconds. This module also has a maximum on-state contact resistance of 0.25 Ω, a maximum backplane current of 550 mA, and an isolation voltage of 2500V AC RMS.
The signal delay of this module 10 ms for both on or off. Its power dissipation ranges from a minimum of 2.6 W to a maximum of 2.9 W. This module also has a thermal dissipation that ranges from a minimum of 8.9 BTU/hr to a maximum of 9.9 BTU/hr. The 1771-OX has an operating temperature of 0-60 ??
