No real-time clock on this variant – it's clean ladder logic only, no time-stamping. Program memory is checked on every power-up, so you know the firmware is intact before the machine runs. Supply voltage range is 19.2...30 V DC, so it handles a weak battery line or a floating 24 V rail. Power draw is 3 W without expansion modules; maximum supply current 100 mA. Cycle time 6...90 ms – fast enough for simple machine sequences, not for high-speed counting. Inputs are resistive type, 24 V DC, 4 mA draw, IEC 61131-2 Type 1. Counting frequency is 1 kHz on those inputs – suitable for counting parts on a conveyor, not encoder feedback. Relay output response time: 10 ms on, 5 ms off. Mechanical durability rated at 10 million cycles. IP20 on the terminals, IP40 on the front panel – typical for control panel mounting. Standards met include IEC 61000-4-2/3/4/5/6/11/12 and IEC 60068-2-27/6, so it’s EMC-hardened for industrial environments. ## Sourcing reality This is a current-production item. No EOL notice, no last-time-buy pressure. I can quote it against an RFQ – just tell me the quantity and whether you need the base unit alone or with expansion modules. No clock means you’re not paying for a feature you don’t use.","metaTitle":"Schneider Zelio Logic SR2A101BD smart relay, 24V DC, 6 input","metaDescription":"Schneider Zelio Logic SR2A101BD compact smart relay. 24V DC supply, 6 digital inputs, relay outputs.
