The module receives digital values through the backplane bus and converts them into proportional field output signals. Its dual-channel design supports independent voltage or current output configuration, allowing separate analog control loops within the same I\/O chassis.\u003c\/p\u003e\n\u003cp\u003eThe module architecture supports industrial control requirements through isolated output circuitry and diagnostic indicators. Signal conversion resolution of 12-bit provides 4096 discrete output levels, while optical isolation separates field wiring from the PLC backplane interface to reduce electrical interference transfer.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What output signal types are supported by the 1771-OFE2\/B module?\u003cbr\u003eA: The module supports selectable analog voltage outputs of +\/-10 VDC and current outputs of 4-20 mA for each channel.\u003c\/p\u003e\n\u003cp\u003eQ: What PLC system is compatible with the 1771-OFE2\/B?\u003cbr\u003eA: The module is designed for installation in Allen-Bradley PLC-5 systems using the 1771 I\/O platform.\u003c\/p\u003e\n\u003cp\u003eQ: What are the backplane power requirements of this module?\u003cbr\u003eA: The module requires approximately 800 mA from the 5 VDC backplane supply and has typical power dissipation of 4.5 W.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eInstall the 1771-OFE2\/B module in a compatible 1771 I\/O chassis with the correct keying and slot configuration before applying power.
