engines and turbines

HELENOS DC 2-02
DATA SHEET
Description
The DC 2-02 is HEINzMANN’s second
generation of digital HELENOS controls for
medium-speed engines and turbines. This highly efcient
speed governor is based on a 32-bit microprocessor.
The DC 2-02 control unit offers up to six analogue inputs, four analogue outputs,
four up to eight digital inputs and three up to seven digital outputs beside two
input channels for inductive speed sensors. An optional CAN or CAN/Modbus
module extension provides the interface for external communication.
In combination with HEINzMANN’s small and medium range actuators or the
Bosch EDC™ pump the DC 2-02 control unit provides the ideal solution for
small- and medium-speed engines and turbine applications.
The advanced DC 2-02 hardware is fully compatible with its predecessor.
All DC 2-01 software versions can be used without any change.

Actuators
HELENOS DC 2-02 is the central
control unit of the HELENOS family of HELENOS Systems Actuator(s)
StG 6/10
HELENOS I
digital control systems. The different
StG 2010/2040/2080
HELENOS II
systems vary in the combination with
StG 16/30/40
applicable actuators. HEINzMANN
HELENOS III
Bosch EDC™
supplies a wide range of actuators for HELENOS IV
