That buys some margin for a sagging 24 V bus or a long cable drop. The base itself is rated for up to 7 A ampacity; that feeds both the module and the loop-through to downstream bases. Insulation voltage is 500 V, surge withstand 6 kV, pollution degree 2 — solid for a control cabinet environment. ## Environmental limits Operation from -25 to +60 °C; above 40 °C you'll need to derate per the manual. Storage and transport go from -40 to +70 °C. Vibration resistance is 15 mm at 6 Hz, 2g up to 500 Hz; shock 6g for 11 ms. That covers most fixed industrial installations without special damping.","metaTitle":"Siemens 3RK1908-0AP00-0JP0 SIMATIC ET 200SP BaseUnit, 24 V D","metaDescription":"Siemens 3RK1908-0AP00-0JP0 SIMATIC ET 200SP BaseUnit for F-DI modules. 24 V DC supply, 7 A ampacity, push-in terminals, 215x30x75 mm.
