FUNCTIONAL DESCRIPTION:

IS200SHRAH2ABC is a HART Enabled Analog Input/Output Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The SHRA board is a compact analog input terminal that connects to the PHRA pack, supporting 10 analog inputs and two 4-20 mA analog outputs. It enables HART communication between the PHRA and a HART-enabled field device. The inputs accommodate two-wire, three-wire, four-wire, or externally powered transmitters. Featuring high-density Euro-block terminal blocks, the board includes an ID chip for system diagnostics. Only a simplex version is available. In Mark VIe systems, the PHRA I/O pack works with the SHRA. The I/O pack plugs into the D-type connector and communicates with the controller over Ethernet. Only simplex systems are supported. All revisions of SHRA are compatible with all PHRAs.

INSTALLATION:

The SHRA, along with a plastic insulator, mounts on a sheet metal carrier, which can be attached to a DIN rail. Alternatively, it can be mounted on a sheet metal assembly and bolted directly to a cabinet. Two types of Euro-block terminal blocks are available:

• SHRAH1 has a permanently mounted terminal block with 48 terminals.
• SHRAH2 has a right angle header accepting a range of commercially available pluggable terminal blocks, with 48 terminals.

Typically #18 AWG wires (shielded twisted-pair) are used. I/O cable shield termination is provided adjacent to the terminal blocks. The following types of analog inputs/outputs can be used:

• Analog input, two-wire transmitter
• Analog input, three-wire transmitter
• Analog input, four-wire transmitter
• Analog input, externally powered transmitter
• Analog input, voltage ±5 V dc
• Analog output, 4-20 mA current

OPERATION:

24 V dc power is available on the terminal board for all the transmitters (transducers). There is a choice of current or voltage inputs using jumpers. HART communication is only possible with the inputs set as 4-20 mA inputs, it will not take place on an input set as ±5 V dc or ±1 mA. The two analog output circuits are 4-20 mA. There is only one cable connection, so the terminal board cannot be used for TMR applications. The following table displays the analog input/output capacity of the SHRA terminal board.

CONFIGURATION:

Configuration of the terminal board is using jumpers. For the location of these jumpers refer to the installation diagram. The jumper choices are as follows:

• Jumpers JP1A through JP8A select either current input or voltage input
• Jumpers JP1B through JP8B select whether the return is connected to common or is left open
• Jumpers JP9A and JP10A select either 1 mA or 20 mA input current
• Jumpers JP9B and JP10B select whether the return is connected to common or is left open.
