IN STOCK ABB DHH805-A Handheld communicator Brand New 

The the DHH805-A is a handheld terminal for device configuration of HART® instruments.

It interfaces to a wide range of devices supporting ABB instruments with an option to support those from third party suppliers.

All supported HART field devices can be configured, polled and trimmed using the Mobility DHH805.

Product description

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.
