About the ZSB-409A

Migatron's ZSB-409A is a 3-channel dc positive polarity zener safety barrier for use in intrinsic safety applications. The 3-channel design has one 24 V dc channel and two 10 V dc channels. The ZSB-409A is compatible with Migatron’s RPS-409A-IS, RPS-409A-IS2 and RPS-409A-IS3 ultrasonic sensors, and combines all of the connections into one convenient package. The ZSB-409A provides for the safe operation of an intrinsically safe electrical apparatus installed in a hazardous gas or dust environment classified as Zone 0, 1, 2, 20, 21, or 22 for ATEX/IECEx, and Class I, II, or III for UL/cUL.

Migatron's ZSB-409A safety barrier is intended for indoor or outdoor use in locations where the temperature does not exceed the specified range (Ta) of the safety barrier. The safety barrier must be installed in a safe area; typically in racks or control cabinets with an appropriate level of protection from dust and liquids. The ZSB-409A is designed for easy installation onto standard 35 mm DIN-Rail, and is fitted with an insulated wire for making the ground connection.
