Athena Controls 25DFB000 Temperature Controls

Athena Controls 25DFB000 Temperature Controller is a single‑loop, panel‑mount controller from Athena’s 18/19/25 family, designed for precise closed‑loop temperature control in industrial heating and processing with a -199 to 450 °F sensing range. It accepts a 100‑ohm RTD input for measurement and uses a configuration that can provide a relay output (B) and an additional analog output path, with optional RS‑232/RS‑485 communications offered on configured models. The series supports ramp/soak control and autotune to simplify setup, and the display resolves temperatures in 0.1‑degree units to help with tight process control. Built for panel mounting, it is rated for use in environments up to a NEMA 4X enclosure with safe ambient operation from 32 °F to 131 °F (0–55 °C) and up to 90% RH non‑condensing. The 18/19/25 family is widely used in process industries, and the 25DFB000 variant aligns with applications that require accurate temperature sensing and reliable control in plastics, packaging, HVAC, food equipment, chemical processing, and related fields.
