Tired of wiring headaches and unreliable data from old field devices? The Endress+Hauser SWA70-AA2B1B8, 2.4 GHz WirelessHART Adapter with Power Supply lets you turn 420 mA or HART sensors into wireless sources in minutes. It solves the problem of costly cable runs and frequent signal loss, giving you a clean, secure link to your control system. If you need fast, safe data without rewiring, this adapter is the answer.
Endress+Hauser SWA70-AA2B1B8, 2.4 GHz WirelessHART Adapter with Power Supply
Many plants still rely on hard-wired HART or 420 mA loops. The cables are expensive, hard to maintain, and can fail in harsh environments. When a loop goes down, production stops and troubleshooting takes time. This adapter replaces the wired link with a 2.4 GHz WirelessHART connection that works up to 250 m outdoors and 50 m indoors. It includes a long-life battery pack or external power, so you get continuous operation without digging new trenches.
Key Features
- WirelessHART communication at 2.4 GHz.
- Nominal transmission rate of 250 kbits/s.
- Indoor range up to 50 m, outdoor up to 250 m.
- One point-to-point HART or 420 mA connection.
- Up to four HART devices in multidrop mode with wide-range power.
- Long-life Lithium Thionylchloride battery pack.
- 24 V-230 V AC/DC external power option.
- Integrated three-LED status display.
