It snaps onto a DIN rail per EN 60715 (35x7.5/15) and measures 30 mm wide, 80 mm high, 100 mm deep — a tight footprint for crowded panels. Galvanic isolation is SELV according to EN 60950-1, so the output side stays safe for control circuits. The 3.5 A rating isn't the whole story — the module delivers 4.3 A at 19 V input and 2.8 A at 28.5 V, with a hard NEC Class 2 limit of 8 A aggregate under fault. That 8 A ceiling is the one that keeps you out of trouble if you're paralleling outputs. The output voltage follows Vin minus about 0.5 V, so it's a buffer, not a regulator — plan your load accordingly. Clearance requirements: 50 mm top and bottom, zero left and right. That means you can pack these side-by-side on the rail, but leave breathing room above and below for convection cooling. The module is rated for natural convection from -20 to +70 °C operating, so those gaps matter in a warm cabinet. The relay contact output signals a fault when either input voltage drops below the switching threshold (adjustable 20 V ±0.5 V to 25 V ±0.5 V) or the output is switched off. Contact rating is 6 A at 42 V AC or 30 V DC, max 100 VA — enough to drive a panel indicator or a PLC input, but don't try to switch a contactor coil directly with it. Snaps onto DIN rail EN 60715 35x7.5/15 — no tools needed. The auxiliary relay contact has its own two screw terminals, same wire range. An optional removable spring-type terminal (6EP1971-5BA00) is listed as an accessory if you prefer spring-cage for vibration resistance.","metaTitle":"Siemens 6EP1962-2BA00 DC Buffer Module, 3.5 A, DIN Rail","metaDescription":"Siemens 6EP1962-2BA00 DC buffer module, 3.5 A rated, 19-29 VDC input, DIN rail mount.
