The SRT2-ID04CL-1 is an active-production 4-point digital input module from the SRT2 series, designed to mount on a DIN rail and powered by 24 VDC. Sealed to IP67, it shrugs off dust and water jets — a fit for machine-mount or washdown zones where a standard IP20 I/O bank wouldn't last. Intended for the Omron C Series backplane; ensure the rack slot is configured for a digital input slice before committing the BOM line.
Active lifecycle means the SRT2-ID04CL-1 is still on the factory build list. For a maintenance-spares purchaser, that translates to no scramble for last-time-buy quantities — you can order a spare now and trust it ships. If you're keeping a C Series line running, this module is a candidate for the 'one in the cabinet' rule: have a spare before the fault finds it.
