Information About 1794-OF4I
The 1794-OF4I is part of the FLEX I/O family, offering isolated analog output capability in a compact, DIN-rail-mounted format. Each of its four channels is individually isolated, allowing flexible deployment in mixed-signal environments and reducing the risk of ground loop interference. The module can be paired with multiple FLEX terminal base models and integrated with any FLEX I/O communication adapter, making it suitable for remote I/O architectures. Common applications include driving actuators, control valves, panel meters, and external analog equipment requiring configurable voltage or current outputs.
Key Features
- Four isolated analog outputs: Supports independent voltage and current ranges per channel.
- Wide signal flexibility: Provides ±10V, ±5V, 0–10V, 0–5V, 4–20 mA, and 0–20 mA output modes.
- High-resolution DAC: Offers 15-bit plus sign resolution for precise analog signal generation.
- Fast update rate: Delivers 2.5 ms or 5 ms module-wide output refresh.
- DIN-rail installation: Compatible with FLEX terminal bases including TB2, TB3, TB3S, TB3T, TB3TS, and TBN.
- Integrated isolation: Channel-to-channel and terminal-to-bus isolation up to 120 V continuous.
- Diagnostic capability: Supports module-level status indications through OK and FLD PWR LEDs.
- Rugged performance: Rated for industrial shock, vibration, and extended temperature storage.
The 1794-OF4I delivers the reliability and precision required for distributed analog output control in FLEX I/O system architectures.
