E-16 Technical Specifications
DC590+ Series DC Digital Drive
Terminal Definitions (Digital/Analog Inputs & Outputs)
User inputs are IEC1131 compliant. Terminal blocks A, B, and C are located on the control board each block being a 9 way plug-in connector. In
addition to terminal blocks A, B and C, terminal blocks G and H provide connections when the two option modules are fitted on the control board.

Digital Output
These outputs are active high and
source current from the terminal to
the load. Thus the load must be
connected between the output and
the signal ground. A free-wheel
diode is included in the output to
protect the output transistor when
switching inductive loads such as
relays.
