Описание
1-channel isolated barrier, 24 V DC supply (Power Rail), Voltage input 0 V .. -20 V, Vibration sensor inputs, Voltage/current field supply, Voltage output 0 V .. -20 V, Up to SIL 2 acc. to IEC 61508, Transfer direction: to the control systempa. This isolated barrier is used for intrinsic safety applications. It provides a floating output to power a vibration sensor (e. g., Bently Nevada) or accelerometer in a hazardous area and transfers the voltage signal from that sensor to the safe area. The device is designed to provide a voltage or current supply to the vibration sensor. Depending on connection the barrier provides 3.6 mA, 5.3 mA, or 8.9 mA supply current for 2-wire sensors, or 18 V at 20 mA for 3-wire sensors.
