Technical Scale: p.s.i. and bar (bar only for T.

U.

V. models). Connections to pressure line: 7/16 – 20 UNF straight output male connector, 1/4 flared female connector. Electrical ratings: the electrical rating of the unipolar SPDT switch, except for versions with dual signal, is 16(16)A 250V~ N.

O. or N.

C.; 1(1) A 250V~ on the opposite side. Model 017 with dual signal: transmitted with terminals 1 and 4 as above; the maximum current between terminals 1–2 and 1–3 is 0.1A 250V~. Compliance: all models are compliant with EN60730–2–6 and EN60730–2–9, and manufactured in accordance with the requirements of standard ISO9001. These thermostats are also compliant with current European standards. Special versions only: USA (UL) and Canada (CSA) 17 FLA 102 LRA 250V~. Terminals of model O17 standard: 1 common, 2 opens when the pressure increases, 4 closes when the low pressure increases and opens when the high pressure increases. Terminals of model 017 with dual signal: 1 common 2 closes the signal circuit when the low pressure decreases, 3 closes the signal circuit when the high pressure increases, 4 closes the signal circuit when the low pressure increases and opens it when the high pressure increases. Cable input: 14 mm insulated bushing. Coolants: suitable to be used with all types of gases. Mounting: two male holes on the rear of the controller for the insertion of M4x6 mm screws (supplied with the thermostat).
