# IOMOD models and types

The IOmod series comprises devices that incorporate various input and output modules. These modules all operate using one of three firmware versions (except for 4Cs4Vs, which uses one of two). These firmware versions serve to distinguish the communication protocols utilized via the RS485 interface. Importantly, all types of IOmod devices employ the same firmware and do not necessitate specific firmware for their respective types. IOmod devices are designed with the capability to automatically identify the hardware type and determine the supported functions.

IOmod finds utility in industrial settings where digital signaling and robust communication are essential. It serves as an ideal solution for applications like data acquisition, control, and process monitoring, particularly in scenarios requiring remote access.
