This is a compact RTAC that supports DIN- and surface-mounting options and delivers all the standard features of an RTAC, making it an excellent option for protocol conversion and secure communication when space is limited. This model includes an optional internal modem and is ideal for small substations, distributed energy resources (DERs), and recloser applications.
