VT 1610-3X/E1/4WRD10-3X

Product Description:

The VT 1610-3X/E1/4WRD10-3X is part of the VT 1600 Servo Amplifiers series by Bosch Rexroth Indramat, made for use with 4WRD10-3X valves. The supply voltage runs on 24 V DC with a tolerance range from -15% to +20%, and includes built-in reverse polarity protection to guard against connection mistakes. The form factor follows the Eurocard layout (100 mm x 160 mm), which makes installation into standard racks straightforward. The total weight comes in at just 0.28 kg, keeping it easy to slot into tight or crowded control enclosures.

The amp draws a maximum current of 0.8 A during operation and can deliver an output current from 0 to 2.5 A depending on load demands. Signal inputs are jumper-selectable — either ±10 V analog or 4–20 mA differential mode. Ramp times are adjustable between 0.01 to 5 seconds, with separate settings for ramp-up and ramp-down. That flexibility helps prevent sudden shifts in output pressure or movement, especially when paired with sensitive valve controls. These products conform to recognized safety and performance certifications, guaranteeing compliance with industry regulations and providing peace of mind for operational safety.

Additional adjustment elements include zero, gain, ramp timing, and dither amplitude and frequency. Dither frequency itself can be tuned from 50 Hz to 400 Hz, which keeps valve spools moving cleanly even when friction or stiction builds up. The output circuit is short-circuit proof, offering a layer of protection when paired with finicky loads or mixed wiring. There’s no flash or extra housing around this amplifier — it’s all function, no frills. The VT 1610-3X/E1/4WRD10-3X delivers steady control when driving hydraulic servo valves in precise motion setups, where tuning and feedback need to respond fast and stay accurate under repeat cycles.
