Product Description:
The VT-VSPA2-1-10c/T1 is a plug-in proportional amplifier card manufactured by Bosch Rexroth Indramat for the VT-VSPA Proportional Amplifiers series. Mounted in a 19-inch rack, the board conditions analog reference signals and drives a hydraulic valve solenoid with controlled current. In industrial automation, it links a PLC command signal to the valve coil and provides ramp generation, current limitation, and feedback points so that flow or pressure follows the requested setpoint.
The operating electronics are powered by a nominal 24 VDC supply, and the total board current remains less than 2 A. A front-edge 48-pin DIN 41612 F connector carries power, command, and feedback lines through a secure rack connection. The differential voltage input has an impedance of more than 50 kΩ, while the separate current input has an impedance of 100 Ω; these values help prevent loading errors at the PLC outputs. Internally, the card provides a regulated monitor signal of ±10 V with ±2% accuracy, allowing downstream devices to receive the command reference. Protective features include a 2 A fuse, a lower operating threshold of 18 V, and an upper operating limit of 35 V.
The power stage limits the solenoid current to 2.5 A, helping prevent the connected valve coil from overheating during sustained demand. Closed-loop stabilization of the coil current uses a feedback branch that can source up to 25 mA. Total electrical losses remain below 50 VA, which helps limit heat accumulation inside the enclosure. Additional tuning connections include a ramp generator with a 10 kΩ load, a potentiometer input with an impedance above 100 kΩ, and an internal command output that can supply the reference signal to external circuits without excessive loading. An actual-value output of ±2.5 V with ±2% accuracy supports signal monitoring, while the adjustable ramp smooths rapid command changes before they reach the solenoid drive stage.
