DHH805-A HART Handheld Communicator - ABB
Time: 2020年04月16日DHH805 is a universal portable configuration tool that allows easy parameterization of ABB and third party HART® instruments. Every HART® field device may be configured, polled, and trimmed using the DHH805.
- The Hand Held Communicator provides a smart interface with HART electronic devices: it is designed to enable the plant engineer to configure, calibrate and troubleshoot the transmitters either before or after field installation.
- The Hand Held Communicator can store in its non-volatile memory hundreds of transmitter configurations.
- The Communicator employs a four line by twenty dot matrix characters LCD and a 23 key tactile feedback keyboard.
- The hand held terminal is based on standard Bell 202 FSK (Frequency Shift Keying) current modulation superimposed on the 4 to 20 mA analog signal: since the energy balance added to the current loop is virtually equal to zero no disturbance or interference occurs on the analog process signal.
- This version of the Communicator, when powered by internal rechargeable batteries, is certified intrinsically safe for use in hazardous locations according to the standard printed label placed on the battery pack.
- Previous：ORing IMC-121FB-SS-SC ethernet to fiber media converters arrived.
