VT 5012S42
The Bosch Rexroth Indramat VT 5012S42 IO card from the VT-5000 IO Cards series is a high-precision industrial interface module designed for solenoid and sensor control in automated systems. This card operates reliably over a wide operating voltage range of 21.6 – 33.6 V DC, supporting embedded control architectures that demand stable power delivery. Packaged in a compact Euro-card format (100 × 160 mm) with a 32-pin male (DIN 41612 type D) connector, the VT 5012S42 weighs only 0.15 kg, minimizing space and load on rack assemblies. Its low-profile front panel height of 128.4 mm (3 HE) ensures compatibility with standard DIN 41494 enclosures.
The VT 5012S42 features precise electrical characteristics tailored for solenoid actuation and sensor feedback. It delivers a maximum solenoid current output of 2.5 A through an integrated output stage with 2 Ω series resistance, establishing a predictable RL time constant for controlled current rise. Continuous operation at 0.6 A rated current with 1.25 A peak current capability meets transient load demands, while internal protection diodes safeguard against overcurrent events. The card’s timing subsystem is governed by an oscillator frequency of 5.4 kHz (with an alternate mode at 2.5 kHz ±10%), optimizing PWM resolution for refined current modulation. Analog input sockets include an angle/valve socket voltage of ±10 V (Ri = 2 kΩ) and a pressure socket voltage of 0 – 10 V (Ri = 2 kΩ) for real-time process monitoring.
Operationally, the VT 5012S42 supports comprehensive sensor integration and high response performance. Inductive swivel angle sensors (type IW9, range ±4 mm) connect via a 3-wire swivel sensor interface, while valve position sensors (type DM2, range ±0.6 mm) use a 4-wire valve sensor interface. The card’s internal oscillator and PWM architecture deliver low-current ripple, reducing thermal stress on solenoids and enhancing positional accuracy in dynamic cycles. It tolerates ambient temperatures from 0 °C to +50 °C without derating, ensuring consistent performance in varied industrial environments. Thermal management is achieved through on-board heat dissipation paths and robust semiconductor selection, extending service life under continuous duty.
System integration is streamlined by industry-standard connectors and Euro-card dimensions for seamless insertion into rack-mounted control cabinets. The VT 5012S42 interfaces directly with Bosch Rexroth Indramat PLCs, motion controllers, and servo amplifiers, enabling synchronized solenoid actuation in assembly, packaging, and valve control applications. Its precise current control and high-speed sensor feedback loops make it ideal for automated processes in hydraulics, pneumatics, and fluid power systems, where reliability and response time are critical.
