Athena Controls 25JFTTBB000 Temperature Controller

Athena Controls 25JFTTBB000 Temperature Controller is a 1/4‑DIN digital temperature/ process controller from Athena’s legacy 25‑series, built for reliable single‑loop control with two independent outputs and dual 4‑digit LED displays that show process value and setpoint simultaneously. The unit covers a 0 to 1400°F range and provides flexible output options, including a solid‑state relay (S.S. RELAY) and a conventional relay output for heating elements and alarm signaling. This 25‑series controller is widely used in industrial ovens, furnaces, plastics processing, and other temperature‑critical applications across chemical, food, HVAC, and manufacturing sectors, with Athena documenting its role in a broad range of process control environments. The compact, 1/4‑DIN form factor is designed for straightforward panel mounting in control cabinets where space is at a premium. Some distributor listings identify this legacy model as discontinued by the manufacturer, signaling that replacements or modern equivalents from Athena’s current line may be more readily available.
