Product Description:
The VT 3000 37 is an analog amplifier card from Bosch Rexroth Indramat’s VT 3000 Analog Amplifiers series. Supplied in a 32-pin Eurocard format, the board slides into standardized racks where it scales voltage references and delivers controlled coil current to proportional hydraulic valves. By translating low-level electronic commands into regulated actuator energy, it links PLC setpoints with motion or pressure outputs on automated machinery.
The card accepts an additional command input of ±6 V, which lets a secondary controller trim or override the main reference without recalibrating the system. A printed wiring depth of 170 mm keeps the electronics fully inside the rack while leaving connector pins accessible at the rear. A stabilized supply of 24 VDC ±10% powers the internal stages; this tolerance window protects operation during minor line fluctuations. The output driver can source up to 800 mA, enough to energize most proportional solenoids without an external booster. Input circuitry will not overload upstream devices because it presents a minimum load of ≥500 Ω; therefore even delicate signal generators can be tied directly to the board.
Over-current protection relies on a 2.5 A fuse mounted on the faceplate, isolating the rack if a field cable shorts. Total dissipation is limited to 30 W, so cabinet cooling can be sized accordingly when several modules operate in the same bay. Service technicians verify loop status through the calibrated test point where 1 mV = 1 mA, translating probe readings into instantaneous coil current without math. Six change-over relays, a maximum coil resistance of 19.5 Ω, and a bias current floor of 20 mA provide additional setup flexibility, while the assembly’s 0.15 kg mass minimizes load on card guides and eases rapid replacement during preventive maintenance.
