Product details

The SR3XT141FU: Cycle time sits at 6-90 ms for the ladder logic engine, and discrete input response from state 0 to state 1 is 50 ms (ladder) or 50-255 ms (FBD). Relay output response: 10 ms to close, 5 ms to open. That spec is consistent with the Zelio family's typical scan rates for slow to moderate process I/O.

The screw terminals accept 0.2-2.5 mm² solid or 0.25-1.5 mm² flexible (ferruled) wire, with a tightening torque of 0.5 N·m. IP20 at the terminal block, IP40 at the front panel. Storage from -40 to 70 °C. Pollution degree 2 per IEC 61131-2; overvoltage category III. Altitude limit 2000 m operating, 3048 m transport.

Compliance and immunity

The SR3XT141FU carries IEC 61000-4-2/3/4/5/6/11/12 at level 3, plus IEC 60068-2-6 and 2-27 vibration and shock. Radiated and conducted emissions meet Class B per EN 55022-11 group 1. The low-voltage directive and EMC directives (IEC 61000-6-2, -3, -4) are cited. For procurement, this means the module is accepted in CE-marked panels without additional filtering for most light-industrial environments. Backup time for the real-time clock is 10 years at 25 °C; clock drift is 12 min/year over 0-55 °C. That clock holds time and date through power cycles as long as the internal battery is fresh.

Sourcing posture

Lifecycle stage is flagged as current production. No EOL or PCN is indicated in the record. Supply is steady through the standard Schneider distribution channel; orders placed against an RFQ will fill without allocation risk for the foreseeable future. If you are substituting into a legacy design, confirm the firmware compatibility with the base CPU revision — the module is functionally identical to earlier SR3XT141 variants but the bus protocol may differ between Zelio Logic generations.

Frequently asked questions

What compliance documentation does the SR3XT141FU carry?

It conforms to IEC 61000-4-2/3/4/5/6/11/12 level 3, IEC 60068-2-27/2-6, EN 55022-11 Class B, and the Low Voltage Directive per IEC 61131-2. The EMC directives IEC 61000-6-2, -3, -4 are also cited.

What does 'Checks Program memory on each power up' mean for this module?

It means the module performs a self-test of its program memory integrity every time power is applied. This is a diagnostic routine common in safety-conscious designs; if memory corruption is detected, the module will flag an error rather than execute faulty logic.
