The values above identify X20SI4100 at catalog level. Verify the installed revision, label and current manufacturer manual before issuing a purchase order or approving a design change.
01 / Intended duty
For X20SI4100, Map safety sensors and test pulses according to the validated machine safety design.
Capture the actual cabinet location, connected equipment, expected operating range and the consequence of a lost signal or network connection. These details turn the X20SI4100 code into a specific engineering requirement.
03 / Acceptance record
For commissioning X20SI4100, Perform the approved safety-function test and record fault detection and restart behavior.
Record date, test conditions, observed LEDs or diagnostics and as-left configuration for X20SI4100. Restore normal control after testing and obtain the site's electrical or safety sign-off where required.
02 / Fit boundary
When replacing or adding X20SI4100, Confirm safety project, wiring diagnostics, approvals and channel allocation. More-channel modules require their own engineering review.
Check X20SI4100 against the as-built wiring, X20 base, terminal block, supply module and controller software. Keep every accessory and revision difference visible in the RFQ; do not approve a look-alike solely from a photograph.
Code alternatives and exclusions
The references below, if any, share a relevant X20SI4100 code stem or functional family. Their ratings, ports, wiring or software may differ; they are not automatic replacements.
No additional exact-stem variant is assigned to X20SI4100 here; seek written manufacturer confirmation for any alternative.
Purchase handover
Quote X20SI4100 exactly, with quantity, required delivery, existing hardware revision and a readable label photograph. Attach the application drawing and network or channel map so the supplier can confirm the right product and accessories.
The buyer should retain a written fit decision for X20SI4100, and maintenance should keep the final settings and test evidence. Do not energize a replacement until the approved checks are complete.
