Drawing only 40 mA at 5 VDC from the FlexBus backplane, the unit maintains high backplane bus communication velocity across PLC-5, SLC 500, CompactLogix, and ControlLogix networks. Configurable hardware input filtering (from 0.25 ms up to 32 ms) suppresses field contact bounce and electrical noise, while 50 V continuous isolation shields the internal backplane logic from severe ground potential shifts.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 1794-IV32 module be replaced while the FLEX I\/O system is powered?\u003c\/p\u003e\n\u003cp\u003eA: Yes.
