It gives you 10 digital inputs (24 V, PLC level 1 compatible), 6 logic outputs, and 2 analog inputs plus 2 analog outputs, all 0...20 mA current loop. The on-board lithium battery holds the real-time clock and pump rotation data for 8 years — enough to survive a multi-year power-down or a line changeover without losing the pump sequencing history. This card is officially obsolete per Schneider's lifecycle status. No direct successor order code is listed, so if you need a drop-in replacement for an existing Altivar Plus multi-pump cabinet, the VW3A3E502 is the part to source. Mounts via the 9-way male SUB-D connector to the Altivar Plus drive backplane; the terminal block (1.5 mm² / AWG 16, 0.25 N·m) handles field wiring for the I/O. The 10 digital inputs are positive logic (state 0 ≤ 5 V, state 1 ≥ 11 V), so standard 24 V PLC outputs drive them directly. The two analog inputs (250 Ω impedance) and two analog outputs (500 Ω impedance) share a 10-bit resolution — adequate for pressure or flow feedback on a pump cascade, not for high-speed servo loops.","metaTitle":"Schneider Electric VW3A3E502 Multi-Pump Card, 24V DC, Obsole","metaDescription":"VW3A3E502 multi-pump card for Altivar drives. 24V DC, 10 digital inputs, 6 outputs, 2 analog I/O, lithium battery.
