Products and Services

Wieland has developed a series of DIN rail mounted terminal block relay modules that are UL-approved for Class I, Zone 2 Hazardous Locations in the oil, gas and petrochemical industry, specifically for Gas Groups A&B (hydrogen), C (ethylene) and D (methane, propane) with a temperature code approval of T6 (85°C).

Designated the flare Series, the relay modules measure just 6.2mm thick and are the thinnest relays in the industry to carry such UL approval. They provide control systems design engineers with a compact solution for high-density input/output wiring applications requiring switching or timing functions, saving up to 80% of the panel space required by conventional "cube" relays.

The relays serve as an interface for field and control devices when there is a need for isolation or timing control functions in a minimum space. In petroleum refining and oilfield applications, flare Series relays provide the required electrical isolation between control and load circuits. They are used as input couplers for remote sensors and switching devices, and as output couplers for valves and contactors.

Wieland's flare Series is one of the industry's most comprehensive product families of DIN rail mounted modules incorporating relay and timer functions. The complete flare Series product line includes both mechanical and opto-coupler relay modules as well as single- and multifunction timer modules. All flare Series modules are packaged in 6.2mm thick DIN rail mounted LTL94 V-0 rated polyamide 6.6 housings.

Available with either screw clamp terminations for #10 - 24 AWG conductors or spring clamp terminations for high vibration and mobile applications accepting #12 - 24 AWG wire sizes, flare series relay modules also feature 2-pole pluggable jumpers as well as 10-pole comb jumpers to reduce wiring time for faster installation.
