Product Description:

The VT 5041-21/1-0V is a Control unit designed by Bosch Rexroth Indramat that is made to precisely handle valves and actuators. It works well with control inputs and transducers that are compatible. For complicated industrial automation command and feedback activities, VT 5041-21/1-0V operates at 24 VDC.

There are analog inputs on the VT 5041-21/1-0V control unit that can be used for pressure control (0–10 V), swivel angle control (±10 V or 0–10 V), and power limit command (0–10 V). Depending on how it is set up, the actual signal input for pressure can be anywhere from 0 V to 20 mA. There are two types of analog outputs: a solenoid output that sends 2.5 A into a 2 Ω load and an oscillator output that sends 5.4 kHz. Depending on the type of sensor, the oscillator's voltage is either 1 V or 3.6 V. The 0–10 V and –10 V to +10 V outputs send feedback signals for the real pressure and swivel angle. The digital part has an enable input that turns on when the voltage goes above 12 V and several low-active or UB-based outputs that show problem status, power limit, and swivel angle control status.

The VT 5041-21/1-0V control unit includes front plate measurement holes for real-time testing. It produces secondary voltages of ±15 V with a ±6% tolerance. To maintain tight loop control, the gadget sends ±10 V valve commands and feedback. Additional specs include a maximum current of 1.25 A and a power limit active output of UB–3 V and 20 mA. The VT 5041-21/1-0V controls voltage correctly and protects signals. It meets industrial automation control needs with consistent voltage output and signal compatibility.

Frequently Asked Questions about VT 5041-21/1-0V:

Q: Does VT 5041-21/1-0V give auxiliary voltages?

A: It outputs ±15 V auxiliary supply at 10 mA. These support external sensor or circuit requirements.

Q: Does VT 5041-21/1-0V support 4–20 mA inputs?

A: Yes, it supports 4–20 mA pressure input with a 100 Ω load. This provides current-loop compatibility for various pressure transducers.

Q: Why does VT 5041-21/1-0V use two sensor types?

A: IW9 and DM2 support different actuator types. Each ensures compatibility with specific inductive or transformer-based feedback systems.

Q: How does VT 5041-21/1-0V provide angle feedback?

A: It delivers ±10 V analog output for actual swivel angle. This enables real-time actuator position monitoring.

Q: Do VT 5041-21/1-0V outputs include fault signaling?

A: Yes, it provides low-active digital fault output. The signal drops to 0 V when an error is active.
