Runs on 24 V DC, burns 3.45 W typical. Comes with the 40-pole push-in connectors in the box, so no separate ordering step. Signal thresholds are standard: +11 to +30 V for a solid '1', -30 to +5 V for a '0'. Input response under 100 µs on the rising edge, 500 µs falling — fast enough for most discrete sensors and simple interlocks. Lifecycle status is current — no end-of-life notice. Sourced directly through the standard Siemens distribution channel; we quote against an RFQ. ## Firmware and diagnostics Ships with firmware V1.0.0 and supports field updates, so you can keep it current without swapping hardware. I&M data (I&M0 to I&M3) is available for asset tracking — handy if you maintain a fleet of S7-1500 racks. Green RUN LED and red ERROR LED give quick visual status. No diagnostic alarm, no hardware interrupt — it's a basic block meant for straightforward I/O, not high-speed cam or safety functions. Unshielded max 600 m; shielded max 1 000 m. Supports two-wire sensors and current-sourcing inputs.","metaTitle":"Siemens 6ES7523-1BL00-0AA0 S7-1500 DI/DQ module, 24V DC","metaDescription":"Active production S7-1500 combi module with digital inputs and outputs, 24V DC, 3.45W, 25mm wide, includes connectors.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Digital Output Modules"],"specifications":{"DI":"Yes","DQ":"Yes","MSI":"Yes","MSO":"Yes","PWM":"No","Depth":"129 mm","Note:":"Supplied incl. 40-pole push-in front connectors","Width":"25 mm","title":"6ES7523-1BL00-0AA0","Height":"147 mm","Counter":"No","RUN LED":"Yes;
