Built‑in function

IOM4.2 multifunctional I/O module provides analogue measuring and regulating drive signals for DEIF DM‑4 marine power management system. It is mainly used for governor speed control and AVR voltage adjustment,meanwhile collects field analogue and discrete signals. Widely used for ship and offshore generator power‑station automation cabinets.

Product Brief

IOM4.2 belongs to DEIF DM‑4 series marine power‑control‑system spare‑part family,rack‑mount multifunctional I/O module specialized for regulating outputs. Different from general‑purpose IOM4.1,focuses on governor‑AVR control. Module address rotary switch must be correctly set before commissioning. Widely applied for marine power‑equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
