£285.00 £317.00



  • Three channels passive zener barrier for power supply, reference and signal. Ex marking: ATEX II (1)G, II (1)D, I (M1)
  • Protection: IIC, IIIC, I (-20 °C ≤ Tamb ≤ +60 °C)
  • Equipped with 3 channels for the protection of the Signal line (CN1/CN4), the Excitation line (CN3/CN6) and the Sense line, for improved signal stability.
  • “SLIM” type case, iper-compact, for DIN rail installation.
  • Temperature of usage: -20°C ÷ +60°C.
  • Storage temperature: -25°C ÷ +70°C
  • Rating: 14Vrms differential and 8Vrms through earth for CN3 connector, 20Vrms for the CN1 & CN2
  • Maximum Security Voltage(Um): 250Vrms
  • Maximum Security Current (current interruption capability): 1500A
  • Degree of protection: IP20
  • Excitation, Signal and Sense Marking: ATEX II (1)G, II(1)D, I(M1)
  • Protection: IIC, IIIC, I (-20°C ≤ Tamb ≤ +60°C)


  • Can connect up to 4 Load Cell of 350 Ohm.
  • Combined use of one or more Zener Barriers (1) GD , implies that the Atex marking of the set of barriers must be upgraded (2) GD , as written in the EN 60079-14 normative.


  • Material: ABS
  • Glands: n.4, ATEX certified.
  • Protection for Case + Barrier:
