The Zener Barrier ZBA1S is the perfect solution for the connection between a weighing terminal and a weight receiver system in the ATEX ZONE. ZBA1S integrates three barriers in one, protecting the excitation line, signal and sense. This feature makes the installation easier, especially in small spaces. This saves time and money.
Three channels passive zener barrier for power supply, reference and signal. Ex marking: ATEX II (1)G, II (1)D, I (M1)
IECEx [circuit(s) in zone 0/1/2]
Protection: [Ex ia Ga] IIC, [Ex ia Da] IIIC, [Ex ia Ma] I (-20 °C ≤ Tamb ≤ +60 °C)
