Product Describe:
HIMA F3349 is an eight-channel safety-related digital output module for 24 V or 48 V DC loads. Documented features include line monitoring, electronic short-circuit protection and open-circuit supervision.
F3349 drives eight monitored DC output channels in a safety-related I/O arrangement, with each field circuit matched to the documented voltage, load and diagnostic behavior.
Exact model: F3349.
Module type: Safety-related digital output.
Output channels: 8.
Nominal output voltage: 24 V DC or 48 V DC.
Retain the documented position, connections and configuration record. Complete controlled diagnostics and a functional test before service release.
Important Notice: Confirm F3349, every companion marking and the recorded acceptance result before replacement.
The technical reference documents the exact product identity and engineering boundaries; the commissioning guide provides separate readiness, connection, verification and handover checks.
Installed-system renewal
Restores the documented F3349 position while keeping the approved host and interfaces.
Controlled maintenance
Supports as-found recording, safe isolation and exact connection restoration.
Compatibility review
Compares the full F3349 marking, host, connectors, settings and companion hardware.
Commissioning evidence
Records diagnostics and a controlled functional test of monitored switching of eight safety-related 24/48 V DC output circuits.
Read the applicable HIMA and site instructions before work. Verify F3349, the installed host and every connected circuit before isolation or replacement.

7
Review hardware and system diagnostics after energization.
8
Functionally verify monitored switching of eight safety-related 24/48 V DC output circuits before service release.
Technical notes
Match F3349 to the complete installed record. Preserve the host position, connections, settings and companion hardware; after replacement, verify diagnostics and monitored switching of eight safety-related 24/48 V DC output circuits under controlled conditions.
Which exact identity should be confirmed for F3349?
F3349 must be matched by its complete model and assembly marking before installation.
How is F3349 classified in this installation?
F3349 is documented as a eight-channel digital output module in the HIMA safety-related I/O context.
What system relationship governs F3349?
Use F3349 only with the recorded HIMA safety-related I/O host, position and companion hardware.
Which documented nominal output voltage applies to F3349?
The approved record specifies 24 V DC or 48 V DC for F3349.
Why should the installed F3349 arrangement be photographed?
The as-found connector, conductor, indicator and adjacent-hardware record prevents mapping errors during replacement.
How must F3349 be isolated before service?
Place the affected equipment in its approved maintenance state, remove connected energy and prove the circuit safe.
What verification follows installation of F3349?
Confirm seating, wiring, settings and diagnostics, then test monitored switching of eight safety-related 24/48 V DC output circuits under controlled conditions.
When may F3349 return to service?
Release requires a recorded acceptance result with the intended function restored and no unexpected alarms or process response.
