Product Description:
The VT-VRRA 1-527-20/V0/2STV valve amplifier by Bosch is designed to control valve solenoids in various industrial applications. Bosch provides high-grade industrial automation devices which are highly reliable and durable for multiple purposes.
This VT-VRRA 1-527-20/V0/2STV valve amplifier operates at a supply voltage of 24 V with a battery voltage range of 21 to 40 V. It can handle rectified alternating voltage between 21 and 28 V using a one-phase as a full-wave rectifier. To smooth any voltage ripple, a capacitor module (VT 11110) is recommended especially if the ripple exceeds 10%. This VT-VSPA series amplifier module is ideal for controlling a pilot control valve (size 6) with a maximum current/VA of 2.7 A/40 VA. The typical power consumption is 37 W with a maximum current draw of 1.7 A which may increase if the supply voltage is low or there are long cable runs. The input signal is a differential amplifier with a range of ±10 V and the recommended signal source is a 10 kΩ potentiometer. The output stage is enabled at voltages between 8.5 and 40 V with a green LED indicating its status. It is housed in a dimension of 100 x 160 x 35 mm enclosure and operates in temperatures ranging from 0°C to 70°C.
This VT-VRRA 1-527-20/V0/2STV valve amplifier supports a position transducer with a supply voltage of ±15 V with both actual value and reference signals in the range of ±10 V. The solenoid output can deliver up to 2.7 A with protection for cable breaks on the actual value line. It is designed to work with cable lengths up to 60 meters for solenoid cables and 4 x 0.5 mm² shielded cables for the position transducer. It includes LED indicators for enable, cable break, and undervoltage conditions.
