HydraForce has launched the EVDR-1206A, a twelve-output, six-input, general-purpose valve driver engineered for hydraulic proportional valve applications in mobile and off-highway equipment. The driver is designed for directional-type valve systems and extends the company’s EVDR valve driver family to address demand for high-channel-count electrohydraulic control.
The EVDR-1206A delivers configurable, closed-loop current control for six proportional directional valves from a single compact unit. Its twelve current-controlled high-side PWM outputs (0–2.4A, 50–1000Hz) and six configurable inputs (0–5V, 0–32V, or ratiometric) allow OEM engineers to manage multi-function machine circuits without additional control hardware. The unit accepts SAE J1939 CAN input or an independent voltage signal and features a single CAN 2.0B communication port for integration into electrohydraulic architectures.
The driver is powered by an ARM Cortex M4 processor running at 128MHz with 512kB program flash, 128kB SRAM and 8kB EEPROM. Its wide supply voltage range (9–32Vdc) makes it suitable for both 12V and 24V vehicle systems, and an IP67/IP69K environmental rating supports operation in the conditions typical of construction, agriculture and mining applications. The unit operates across a temperature range of –40 to 80°C (–40 to 176°F).
The EVDR-1206A is configured using HF-Impulse 2.0, HydraForce’s web-accessible configuration and programming software, which allows engineers to define metering profiles, ramp rates and control parameters. Configuration is performed via CAN, and full technical documentation and the HF-Impulse 2.0 application are available through the HydraForce Electronics Portal.
“The EVDR-1206A is a new, higher I/O valve driver with a rugged and compact design that can be mounted independently or attached to your sectional valve or manifold. It adds additional I/O capacity and shares hardware with the upcoming fully programmable ECDR-1206A. Both units will work with HF-Impulse 2.0 configuration and programming software,” says Chris Behling, electronics product portfolio manager at HydraForce.
