FOXBORO E69F-TI2 Eex-I Current-to-Pneumatic (I/P) Converter

Product Description

The E69F-TI2 Eex-I is a field-mounted Foxboro E69F series current to pneumatic I/P converter. It converts 4–20 mA DC analog control signal into standard 3–15 psi (20–100 kPa) pneumatic output signal for driving pneumatic control valves, actuators and positioners. The suffix -T means threaded explosion-proof housing; I stands for 4–20mA input, 170Ω input impedance, direct/reverse action selectable. Eex-I denotes ATEX intrinsically safe certification for hazardous area installation.

FAQ

Q: What does Eex-I mean?
A: Eex-I is old ATEX marking for intrinsically safe (Ex ia), approved for explosive gas zone 0/1 hazardous locations.

Q: What is the difference between E69F-TI2 and E69F-BI2?
A: -T = threaded cover explosion proof; -B = bolted cover housing variant.

Q: Is this I/P converter discontinued?
A: Yes, Foxboro E69F series is end-of-life, available as surplus, refurbished tested spare parts only.

Q: Does it need safety barrier when used in hazardous zone?
A: Eex-I version is intrinsically safe; it must be matched with approved intrinsic safety barrier on the safe side.
