Rexroth R901044346 VT‑VPCD‑1‑18/V0/1‑0‑1 Amplifier Card
The Rexroth R901044346 VT‑VPCD‑1‑18/V0/1‑0‑1 is a plug‑in proportional valve amplifier card for hydraulic drive systems. It receives analog set‑point signals from PLC or motion controller, and outputs drive current to control Rexroth proportional hydraulic valves for precise pressure and flow regulation.
This European‑standard slot‑mount amplifier integrates signal processing, closed‑loop control and fault monitoring circuits. It is a critical aftermarket spare for maintenance, overhaul and retrofitting of hydraulic press, metallurgical machinery and industrial hydraulic automation equipment.
