FM Approval Intrinsic Safety Barriers

For most non-voltage producing devices located in a hazardous area, a single zener barrier that is negative-earth-grounded can be used for intrinsic safety. Instrumentation that produces an output (signal conditioners) usually requires two barriers, one for each "floating" lead. Here, a dual-channel... [See More]

• Barrier Type: Zener Barrier
• Application: 4-20 mA 2-wire Transmitters; Switches; Solenoid / Audible Alarms

• Mounting Options: Din Rail Mounted (optional feature); SurfaceMount (optional feature)
• AC or DC: DC

Application. 9106B is a 1- or 2-channel isolated 1:1 repeater barrier for intrinsic safety applications. The device supplies 2-wire SMART transmitters and can also be used for 2-wire SMART current sources. HART ® & BRAIN protocols are supported and are transferred bi-directionally. 9106B can...
