VT-SSPA1-50-10/V0/0-24

Product Description:

The model VT-SSPA1-50-10/V0/0-24 is a Plug-in Proportional Amplifier designed for solenoid operated pressure control and directional valves. It operates without closed loop position control and is suitable for mounting on a valve connection base per EN 175301-803. This amplifier supports 90 degree incremental mounting on the solenoid.

This Bosch Rexroth Indramat VT-SSPA1-50-10/V0/0-24 plug-in amplifier features a maximum current adjustment of 2.6 A with a nominal current factory setting of 2.5 A. The biasing current of this amplifier is adjustable between 0...350 mA with a factory setting of 100 mA. This amplifier supports both proportional and switching command value inputs with a 0...10 V proportional range. The input resistance is 20 kΩ. It incorporates a dither frequency potentiometer that ensures stability and performance optimization. The clock frequency at maximum current is 305 Hz and the ramp time is adjustable between 60 ms to 5 s. This model has a minimum coil inductance requirement of 10 mH and a maximum cable inductance of 100 μH. Power consumption remains under 60 VA that ensures energy efficiency. It operates at a 24 VDC supply voltage with a maximum voltage of 35 V and a minimum of 18 V.

The VT-SSPA1-50-10/V0/0-24 plug-in amplifier includes a regulated adjustable maximum current feature that allows command values exceeding 120 % when using differential input. It also has a ramp generator for separate up/down control along with a zero potentiometer for biasing current adjustment. This model connects via four screw terminals and accommodates cables with diameters ranging from 4.5 to 11 mm. This VT-SSPA Plugin Proportional Amplifier features an IP65 protection rating per EN 60529 that makes it resistant to dust and water when properly installed.
