DAQ offers custom retrofits for all types of existing RTUs. Whether replacing obsolete equipment or adding advanced functionality to existing SCADA systems, Callisto remotes provide an economical solution for large-scale expansion projects or simple hardware upgrades.

By utilizing existing field wiring, the modular approach of the Callisto product line reduces investment in running additional cabling. Through analysis of existing equipment, including cabinets, terminal blocks, power supplies, relays and wiring, DAQ engineers are able to design a retrofit "kit" that can be easily installed into existing assemblies. Individual modules or complete multi-card remotes can be integrated with legacy equipment, bringing state-of-the-art technology to outdated systems.

DAQ provides compatibility with equipment from numerous manufacturers, including (but not limited to): ACS, CDC, Chrysler, GE, G-TAC, L&N, Moore Systems, Tasnet and Valmet.
