Product Detail

Specifications

The PLC 1794-OE4XT is a four-point analog output module for the FLEX I/O XT system. Its four single-ended, nonisolated channels can be configured for current or voltage output, while the XT design supports an operating temperature range of -20 to +70 °C. Channel configuration, terminal-base selection, mechanical keying and wiring must follow the official installation instructions.

FAQ

Which FLEX I/O terminal bases are approved for PLC 1794-OE4XT?

Use only a compatible terminal base listed in the official installation instructions. Confirm the base wiring, shielding provisions and terminal torque before installation.

What analog signal ranges can PLC 1794-OE4XT generate?

Each channel can be configured for 0-20 mA, 4-20 mA, 0-10 V DC or -10 to +10 V DC operation.

How should PLC 1794-OE4XT be mechanically keyed before insertion?

Set the terminal-base keyswitch to position 4, fully extend the Flexbus connector and align the module pins before seating the unit.

What external power is required by PLC 1794-OE4XT?

Provide a nominal 24 V DC supply within 10.5-31.2 V DC, including no more than the specified 5% AC ripple.

What should engineers check when commissioning PLC 1794-OE4XT outputs?

Use shielded signal wiring, configure every channel for the intended current or voltage range, and verify the load is within the published limit before enabling commands.
