Wirelesshart Sensors Adapter Basic Operation

A1110 collects dynamic variables, process data and alarm information of HART device and uploads the information to WirelessHART network.

Wirelesshart Sensors Adapter HART port

HART port is connected to traditional HART device. A1110, as HART master, communicates with traditional HART device in the 4-20mA circuit, collects connected HART device information and uploads the information to the WirelessHART network. A1110 can also serve as HART slave device, configured by configuration software (or HART communicator).

Management and communication of sub device

A1110 can support up to 4 HART device connections. WirelessHART gateway can get network information of A1110 and HART devices and communicate with HART devices through A1110. A1110 uses Burst mechanism to upload data periodically, and users can configure the data upload time flexibly.

Wirelesshart Sensors Adapter Physical Specifications

Electrical connections

When connected to a 4-20 mA supply loop, the A1110 is self-powered by energy harvesting.The A1110 causes a 2.5V drop in the loop, but it does not affect the 4-20 mA signal in the loop.

Power supply

The minimum load in the loop is 250 Ω.

For proper operation of sub-equipment, the loop supply must have a minimum 2.5 V margin at 250 Ω load.

For proper operation of sub-equipment, the loop supply must have a minimum 2.5 V margin at 250 Ω load.

The supply voltage limit is 30 VDC.

Wirelesshart Sensors Adapter Installation

Installation Method

Usually A1110 is directly connected onto conduit entrance of HART device. 1/2 NPT male coupling of A1110 can be directly installed onto housing of HART device. For the field devices with other type couplings, such as M20, screw adapter can be used.

1. Install HART device based on standard installation practices, and ensure to use qualified screw sealant on all the screw couplings.

2. Connect A1110 onto HART device according to picture, if A1110 is installed into conduit entrance of HART device.

3. Please refer to Figure 3-3 ~ Figure 3-9, connect A1110 adaptor to HART device.

4. Close shell cover of HART device, but don’t screw it over-tightly, to avoid damage the device.

Wirelesshart Sensors Adapter Direct Installation

Antenna

A1110 antenna is built-in omnidirectional antenna. A1110 shall be vertically installed (horizontal installation will weaken signal), and over 30cm distance from any metal. A1110 may be disturbed by nearby other 2.4 GHz ISM frequency band signal, and these disturbances may cause intermittent message retransmission and loss. To keep optimal antenna signal intensity, shall timely clear away accumulated materials on surface of the antenna, such as dust, fiber, snow and ice. Pay attention that the antenna not to be subjected to too big external force, avoiding damage.

Wirelesshart Sensors Adapter Wiring Port

The following table describes A1110 wiring and colorful wires’ function. These wires all are drawn out through 1/2NPT outlet of A1110.

Wirelesshart Sensors Adapter Wiring Method of Being Repeater

A1110 can be alone taken as repeater. Now A1110 does not connect to other HART devices, and usually is put in the place where signal cannot arrive or is weak, to route other WirelessHART devices in the network. It has improved reliability of the whole WirelessHART network and path stability.

A1110 as repeater usually uses external power supply (such as battery, other DC power), voltage range is 11-30VDC. Purple lead connects power supply (+) positive pole, yellow lead connects power supply (-) negative pole. External power is available if using WirelessHartMPT configuration software. Other wiring is shown in picture.
