Product Description:
The VT-SWMA-1-10A/V0/0 is a plug-in proportional amplifier card manufactured by Bosch Rexroth Indramat within the VT-SSPA Plugin Proportional Amplifiers series. The module slides into a standardized rack and converts low-level command voltages from a PLC into controlled coil current for servo-hydraulic valves. By handling signal amplification and offset adjustment on the card, it enables industrial automation systems to position cylinders or regulate pressure with consistent, temperature-stable performance.
Electrical integration is centered on an operating rail of 24 VDC. The amplifier remains functional as long as the supply does not fall below 18 V, and it tolerates surges up to 35 V, providing headroom for battery-backed or unregulated sources. Internal current draw reaches a maximum of 0.5 A, so cabinet fuse requirements remain modest, while overall power consumption is limited to 12 VA. These values indicate the thermal load and help determine the required conductor cross section when several cards share the same bus. Supply voltage outside this operating range causes the drive stage to disable, preventing unstable valve behavior.
The control stage delivers a nominal output of ±6 mA, matching the magnetizing requirements of typical Bosch Rexroth two-coil valves. During initial setup, the zero-balancing circuit permits an offset range of ±30 percent, allowing the valve spool to be centered without external trimmers. Field wiring terminates at 12 screw terminals for power, command, and feedback lines. The electronics have an IP20 protection rating, so the card must be installed inside a closed control panel. The board clips onto a DIN rail of type TH 35/7.5, enabling tool-free mounting and consistent grounding across multiple amplifier slots.
