The VT-VSPA1-1-C10 by Bosch Rexroth Indramat is a high-functioning Valve Amplifier, notable for its capacity for either current or voltage input. It provides reverse polarity protection and can detect cable breaks in a 4mA to 20mA range. Compatible with a Type VT 3002-1-2X/32D single cardholder, this unit doesn't accommodate a power supply unit. The accessory's command value voltage can be adjusted directly or using an external potentiometer, with a pre-set differential input of 0 to 10V, though the value can be altered to 0mA to 20mA or 4mA to 20mA using DIL switches. The valve amplifier exhibits a "ready-for-operation" output signal when correctly operating, which is facilitated by a +24VDC operating voltage and a 2.5A slow-blow fuse. Be advised that both solenoid conductors and command value lines require shielding and operational issues could be due to incorrect voltage or a faulty fuse.
