Electrohydraulic Axis Position Control Solution — Atos Z-ME-KZ-PS | Z-ME Series
The Atos Z-ME-KZ-PS is a dedicated digital position controller card engineered for closed-loop electrohydraulic axis control. Designed for demanding industrial environments, it interfaces directly with proportional valves and linear/rotary position transducers to deliver precise, repeatable positioning across a wide range of hydraulic actuator applications.
Where This Product Is Used
Engineers and system integrators specify the Z-ME-KZ-PS in applications where hydraulic actuator position must be controlled with high accuracy and dynamic response:
- Injection Molding Machines — Precise clamp and injection axis positioning for repeatable shot-to-shot quality
- Metal Forming Presses — Hydraulic press ram position control for bending, stamping, and deep-drawing operations
- Steel Mill Rolling Equipment — Roll gap control and strip thickness regulation in hot and cold rolling lines
- Die Casting Machines — Shot sleeve and intensifier position control for consistent casting density
- Marine & Offshore Hydraulics — Deck crane boom and winch position control in harsh environments
- Test Rigs & Fatigue Machines — Servo-hydraulic actuator control for material and component testing
- Forestry & Mobile Machinery — Boom and blade positioning on excavators and forestry harvesters

Application-Specific FAQ
Q: Can the Z-ME-KZ-PS control a servo valve instead of a proportional valve?
A: Yes, provided the servo valve driver accepts a ±10 V command signal. The Z-ME-KZ-PS outputs a standard ±10 V analog signal compatible with most servo valve amplifiers. Verify the current capacity of your valve driver separately.
Q: What position transducer types are compatible?
A: The Z-ME-KZ-PS is designed for use with resistive linear potentiometers and LVDT-type transducers. SSI encoder compatibility depends on the firmware revision — contact us to confirm your specific transducer model.
Q: Can I use this card with a Siemens S7-1200 or S7-1500 PLC?
A: Yes. The ±10 V analog output from a Siemens SM 1232 or equivalent AQ module connects directly to the Z-ME-KZ-PS command input. No special interface module is required.
Q: Is this card still in production?
A: The Z-ME-KZ-PS is a legacy Atos product. Konmask.com maintains stock for MRO replacement. For new machine designs, Atos recommends the current Z-ME or E-ME digital axis card series — we can advise on migration.
Q: What is the warranty on this product?
A: Konmask.com offers a 90-day functional warranty on all electrohydraulic control electronics. Extended warranty and exchange programs are available — contact us for details.
