Product Description:
The VT-VSPA1K-1-10C is a proportional amplifier card from the VT-VSPA Proportional Amplifiers series produced by Bosch Rexroth Indramat. As a plug-in controller for electrohydraulic valves, the card converts low-level command signals into regulated coil current so that spool position follows the demanded value in closed-loop motion or pressure circuits. It is installed on standardized Eurocard guides inside control racks, allowing straightforward integration into industrial automation cabinets.
The amplifier is powered from a nominal 24 V DC supply and will continue operating down to 22 V while tolerating surges up to 35 V. Under full excitation, the unit draws no more than 50 VA and its peak current requirement is limited to 1.8 A, which helps with power-supply and wiring selection. A linear actual-value scale of 1 mV per 1 mA simplifies feedback calibration, and the command input channel interprets +9 V as +100% demand so analog controllers can drive the valve range directly. Incoming and outgoing conductors land on a 16-pole terminal strip, and the onboard circuitry is protected by a 2.5 A slow-blow fuse that withstands short inrush events while opening on sustained overloads.
The card delivers a regulated output of ±9 V that can source or sink up to ±25 mA; this reference feeds internal stages and remains stable across the specified supply window. For load devices, the card supports two preset solenoid resistances: 5.4 Ω for 1.6 A coils and 19.5 Ω for 0.8 A coils, supporting predictable current loops when matched with Rexroth proportional valves. Physical dimensions of 100 x 160 mm follow DIN 41494 Eurocard format, and the bare board weight of 0.1 kg keeps rack mass low. The fuse position, terminal strip orientation, and shallow card depth leave adjacent modules accessible during service.
