Push-in terminals on both the main and auxiliary/control circuits accept 0.5 to 2.5 mm² solid or stranded wire (18–10 AWG for the supply). The single digital input is Type 1 per EN 61131-2, with a signal-1 threshold of 15–30 VDC and signal-0 at 0–5 VDC. That means it will reliably read a standard 24 VDC PLC output or sensor, and reject leakage below 5 V — no special conditioning needed. Storage and transport tolerate -40 to +70 °C. Vibration resistance is 15 mm at 6 Hz and 2g up to 500 Hz; shock rated at 6g for 11 ms. Pollution degree 2 — suitable for a typical industrial control cabinet environment. Dimensions: 30 mm wide, 215 mm tall, 75 mm deep. Mount vertically or horizontally. Push-in terminals: strip 8–10 mm, push solid wire or ferrule straight in. Release with a 0.6 x 3.5 mm slot screwdriver. No re-torquing needed — spring cage holds through vibration.","metaTitle":"Siemens SIMATIC 3RK1908-0AP00-0EP0 BaseUnit, 7 A, 24 VDC, DI","metaDescription":"Siemens SIMATIC 3RK1908-0AP00-0EP0 BaseUnit, 7 A ampacity, 24 VDC, push-in terminals, 75 mm depth.
