| SPECIFICATION / VALUE | DETAILS & BENEFITS |
|---|---|
| Item Condition | USED — Thoroughly inspected second-hand programmable controller stock. Both modular housings are fully structural with crisp status marker labels, internal bus backplane connection tracks interface securely, and all wire terminal paths are clean and verified. Manufactured in 2016. |
| Product Type | PLC Digital input/output expansion signal block (SM 1223 DI 8 x 24V DC, DQ 8 x Relay configuration). |
| Model & Part Number | SIMATIC S7-1200 Series / Part Number 6ES7 223-1PH32-0XB0 (Firmware/Hardware state FS: 02). Conforms strictly to industrial logic machinery codes. Certified by UL, CE, EAC, KC, and FM standards. |
| Digital Inputs (DI) | 8 Digital Input channels integrated directly onto the upper terminal matrix. Rated at 24V DC sink/source with an immediate 4mA signal threshold consumption capacity. |
| Digital Outputs (DQ) | 8 Digital Output dry relay changeover channels. Supports switching capacities up to 30V DC or 250V AC with a heavy continuous current load rating of 2A per contact. |
| Supply & Consumption | Powered via an auxiliary line terminal tracking at 24V DC requiring an operational continuous current threshold of 85mA. |
| Mounting Configuration | Compact modular profile engineered for quick tool-free DIN-rail attachment or direct panel screw grid placement. Calibrated for reliable thermal execution under 55°C horizontal mounting or 45°C vertical mounting constraints. |
| Value Advantage | Genuine German engineering by Siemens. High-density pluggable terminal design accelerates field replacement cycles while saving significant installation workspace inside dense electrical sub-panels. This matching 2-piece expansion bundle offers plant facility managers an incredibly economical alternative to build up spare component inventories. |
