VT 4770 S20
The VT 4770 S20 IO card, part of the VT-5000 IO Cards series by Bosch Rexroth Indramat, delivers a robust solution for industrial data control with a compact 100 x 160 mm Euro-card footprint. Designed to operate on 22–35 VDC (nominal 24 VDC, +40%/–10%), this module supports energy-efficient operation with a power consumption below 50 VA and a current consumption of less than 2 A. Weighing just 0.15 kg, the card meets stringent space and weight constraints in automation racks. Featuring a self-clocking output stage, it provides a clock frequency of up to 1.5 kHz and maintains timing stability via an oscillator frequency of 2.5 kHz ±10%. The front panel conforms to Euro-card standards with a 3 HE (128.4 mm) height and a dual-width design of 7 TE on the component side and 1 TE on the solder side.
In performance terms, the VT 4770 S20 supports precise signal acquisition and actuation through dual 0 to ±16 V sockets (100 Ω input impedance): the Actual-position socket and the Command socket. The module’s adjustable ramp time range of 30 ms to 5 s (±20%) enables smooth solenoid drive profiles, with dedicated solenoid outputs rated at 1.8 A ±20%, R=5.4 Ω (VT5005) and 2.2 A ±20%, R=10 Ω (VT5006) at 20°C. A built-in ±9 V regulated output delivers up to 25 mA load with 1% accuracy, ensuring stable reference voltage for auxiliary circuits. Connectivity is provided via a 32-pin male DIN 41 612 form D connector, guaranteeing robust signal integrity in harsh environments. The combination of low inertia electronics and a high clock rate ensures precise timing and quick response for motion control loops.
Engineered for high reliability, the VT 4770 S20 operates across a temperature range of 0 °C to 50 °C and carries a 1-year warranty against manufacturing defects. Its compact, lightweight design integrates seamlessly into standard automation racks, simplifying system expansion and maintenance. The durable connector interface and controlled voltage outputs minimize electromagnetic interference and extend service life. Ideal for valve control, position feedback, and timing-sensitive applications, this IO card excels in packaging machinery, process automation, and industrial robotics. Bosch Rexroth Indramat’s rigorous testing and quality assurance processes ensure consistent performance, making the VT 4770 S20 a dependable component in complex automation networks.
