SEC3IO

Compact controller with I/O module for DIN rail mounting

  • SEC3IO is an embedded controller designed for use in industrial applications. Compared to the basic system SEC3 it comes with an additional I/O module. It has no rotating parts. A fan is not required due to the low power requirement.

    SEC3IO has two serial RS232/RS422/RS485 interfaces and two Ethernet adapters. Thanks to a redundant power feed-in, different input voltages can be used.

    SEC3IO is used in combination with the product ip4Cloud/SEC3IO. The system is supplied with the newest version of our real-time ipLinux operating system.

    The device is equipped with a status relay, which can be freely configured by the software. In the case of power failures or non-fulfillment of a user-defined condition a changeover switch switches into the idle state "FAIL".

    Various diagnostic functions are available via built-in LEDs. A power indicator, transmit and receive indicator for the serial interfaces as well as an indicator for the network controller provide information about the current operating status. A CPU LED indicates the operating mode of the software.
