Product Description:

The VT-SSPA1-1-1X/V0/0-24 is a plug-in proportional amplifier card from Bosch Rexroth Indramat’s VT-SSPA Plugin Proportional Amplifiers series. It mounts on a standardized Eurocard rail. The module conditions command signals so a hydraulic solenoid receives controlled current for accurate directional or pressure-valve response in industrial automation assemblies.

The amplifier operates from a regulated 24 VDC supply and draws a nominal load current of 1.6 A. An internal pulse-width output stage switching at 340 Hz modulates coil current smoothly, helping the valve react predictably during command changes. Input resistance is 20 kΩ, so the command port places only a light electrical load on the upstream controller. The card also accepts reduced supply voltage to maintain dependable control in practical cabinet conditions.

A bias trim potentiometer establishes a baseline current of 100 mA, which supports spool centering before the command signal increases output. The circuit can rise until the board reaches its 35 V ceiling, giving the amplifier enough headroom to drive the connected valve properly. Environmental protection reaches IP65 when all four screw terminals are fully engaged, helping the assembly resist dust and water exposure. For stable electromagnetic behavior, the connected coil must provide at least 15 mH of inductance.
