Bosch Rexroth VT5004S22R1 Amplifier Card

The Bosch Rexroth VT5004S22R1 Amplifier Card is a VT-5000 series analogue amplifier module designed to act as a valve driver within Rexroth Indramat control systems. As part of the VT-5000 IO Cards family, this card provides amplified analog outputs for proportional valve applications, bridging a controller’s signal to the valve actuator. The VT5004S22R1 carries the R1 revision designation and is commonly referenced by variant codes such as VT5004-S-22 in distributor catalogs. Available through Rexroth and authorized distributors, it is widely stocked as a spare part for VT-5000 installations. In Rexroth documentation and product lines, analogue amplifier cards are used for precise, proportional valve control in industrial automation environments, including configurations that support 4/3 proportional directional valves.
