System compatibility

AHAG-K-2310-0-3 belongs to Rexroth hydraulic proportional control amplifier family,matching Rexroth proportional hydraulic valves,widely used for machine tools,presses and metallurgical hydraulic control cabinets.This is a legacy spare part for hydraulic equipment maintenance replacement.

Function

AHAG-K-2310-0-3 is a plug-in proportional amplifier board.It receives analog setpoint signal from host controller,converts command signal into stable driving current to control proportional valve spool position.It realizes closed-loop current regulation for proportional valve,precise adjustment of hydraulic flow and pressure.

Installation

Insert AHAG-K-2310-0-3 into standard control subrack,tighten front panel fixing screws.Connect 24VDC power,command signal cable and proportional valve coil wiring according to wiring diagram.Check shield grounding before power-on commissioning.

Interface

‑24V DC power terminal

‑Analog command signal terminal

‑Proportional valve coil output terminals

‑Backplane bus connector

Circuit feature

Closed-loop current control circuit,high signal resolution,low drift,built-in short-circuit protection,strong anti-interference,suitable for harsh hydraulic workshop environment.

Feature

AHAG-K-2310-0-3 is obsolete Rexroth spare part.Typical faults:signal channel drift,coil drive circuit burnout,component aging,backplane contact failure.Inspect signal input and valve driving output before replacement.This amplifier card must match the corresponding proportional valve type,direct substitution without inspection is not recommended.

Diagnostic

When amplifier board fails,the proportional valve cannot respond to control signal,hydraulic pressure or flow adjustment abnormal,system will trigger hydraulic control alarm.

Built‑in function:Analog signal processing,proportional valve coil current driving,closed-loop current regulation,hydraulic pressure and flow precise control,used as Rexroth hydraulic proportional system spare replacement.

Product Brief

AHAG-K-2310-0-3 is Rexroth plug-in proportional valve amplifier card for hydraulic proportional control loop.Verify power supply,signal type and proportional valve compatibility before ordering.ESD protection required during handling and installation.
