The VT-VSPA1K-1-1X-002-15SEC is a valve amplifier by Bosch Rexroth used to control proportional pressure valves without electrical position feedback. It supports components of series 10 to 19 and features a differential input that is switchable from voltage to the current input. This amplifier's connection is via a 16-pole terminal strip, and it does not have a front plate. It is equipped with one solenoid as actuating element and is built as a Eurocard printed circuit board of 100mm width and 160 mm height according to DIN 41494. Its solenoid conductor has protective features, including cable break detection and short circuit protection. It also has a reverse polarity protection feature for its voltage supply.

An operating voltage of 24 VDC with tolerance between +40% and –5 % is required to operate the VT-VSPA1K-1-1X-002-15SEC. Its maximum power consumption is 50VA, and the maximum current consumption is 1.8A. It has a ramp generator that generates a ramp-shaped output signal from a given stepped input signal, and its ramp time can be set separately for upwards and downwards directions. This ramp time ranges from 30ms to approximately 1 second or 5 seconds. It has a LED display that shows the 'ready for operation' message. Its admissible operating temperature range is 0°C to 50°C.
