Description
Product Overview
The DELEM DM-103VA 8576-001 is a dedicated control module for press brake machinery, built to manage hydraulic bending axes and coordinate auxiliary motion within a machine’s control architecture. Part of the DELEM DM-10x Modusys family, it combines axis-control functions, encoder interfaces, analog signal handling, and digital I/O in one unit. Its main role is to regulate Y1 and Y2 positioning, maintain synchronization between the two sides of the bending beam, and support additional functions such as pressure regulation and crowning control. These functions are important where uneven axis movement can affect bend angle, machine alignment, or finished-part consistency.
The DM-103VA integrates valve-amplifier functions for proportional hydraulic valves and supports encoder feedback for position and motion control. Its documented interfaces include four analog inputs, eight digital inputs, eight programmable input/output points, and eight digital outputs. The module also provides an HSB interface using an RJ45-type connector for communication with compatible DELEM Modusys components. Power requirements are documented as 18–30 VDC in the technical overview; a distributor lists 24 VDC nominal and 0.7 A nominal current. These values should be checked against the specific module documentation and machine wiring before installation.
For maintenance teams, the DELEM DM-103VA 8576-001 is a legacy component that calls for careful identification before replacement. Matching the model name alone is not enough: verify the type number, connector layout, axis feedback arrangement, valve wiring, machine-specific configuration, and the role of the auxiliary axis. A physically similar module may not have the same I/O assignment or control configuration. Because the model is listed as discontinued, procurement should also establish the unit’s actual condition and request functional test details where available.
Product Introduction
The DELEM DM-103VA (8576-001) provides integrated control functions for hydraulic press brake axes and an auxiliary servo axis. Its combination of encoder feedback, proportional-valve control, analog inputs, and digital I/O supports positioning, synchronization, and machine-specific control sequences.
When sourcing this discontinued module, confirm the complete part number and compare the replacement against the installed unit’s wiring and configuration. Confirm actual condition with supplier, including whether the module has been tested under operating conditions.

Frequently Asked Questions
Q1: What is the DELEM DM-103VA used for?
It controls hydraulic Y1/Y2 axes and supports an auxiliary servo axis on press brake machinery. Its functions include position control, axis synchronization, proportional-valve control, and pressure or crowning-related control.
Q2: What power supply does the DM-103VA require?
The technical overview specifies 18–30 VDC, while distributor data lists 24 VDC nominal. Verify the installed machine’s supply and wiring before applying power.
Q3: Is the DM-103VA still manufactured?
Available product listings identify it as discontinued. For existing machines, sourcing a tested legacy unit or evaluating a documented machine-control upgrade may be necessary.
Q4: Can it be replaced with a DM-103 or DM-103V?
Do not assume direct interchangeability. Compare type numbers, connector pinouts, firmware or configuration requirements, axis-feedback interfaces, and machine-specific wiring before approving a replacement.
Q5: Does replacement require machine reconfiguration?
It may. The required work depends on the machine builder’s implementation, retained configuration, axis feedback, and valve-control wiring. Back up available settings and document the existing connections before removal.
Q6: Can the module be hot-swapped?
Do not assume that live replacement is permitted. Follow the machine manufacturer’s isolation procedure and verify the module’s removal requirements before disconnecting it.
Q7: What should be checked before purchasing a used or refurbished unit?
Confirm the exact DM-103VA / 8576-001 marking, connector and terminal condition, visible damage, and available functional test results. Ask whether encoder feedback, analog I/O, digital I/O, and valve-control outputs were tested. Confirm actual condition with supplier.
