GE IS220PHRAH1B Hart Analog I/O Pack Description: The IS220PHRAH1B is GE Mark VIe HART® (Highway Addressable Remote Transducer) enabled analog I/O pack. It acts as the electrical interface between one or two I/O Ethernet networks and an analog input/output terminal board. It consists of two key components: a BPPx processor board—common to all distributed I/O packs—and a dedicated acquisition board designed specifically for analog input functions.
This I/O pack can handle up to 10 analog inputs, with configurable options to suit different field requirements. The first eight inputs can be set up as either +5 V voltage inputs or 4-20 mA current loop inputs. The remaining two inputs offer flexibility as well, supporting either +1 mA or 4-20 mA current input configurations. Load termination resistors for current loop inputs are located on the terminal board, and the PHRA module detects voltage across these resistors to capture input signals accurately. Beyond input capabilities, the IS220PHRAH1B also includes two 4-20 mA current loop outputs. A key feature in 4-20 mA mode is its ability to relay HART messages between HART-enabled field devices and an Asset Management System (AMS). Notably, any of the pack’s input or output channels can be used to connect these HART-enabled field devices.
For connectivity, IS220PHRAH1B uses dual RJ-45 Ethernet connectors for network input and a 3-pin port for power input. Output is delivered via a DC-62 pin connector that mates directly with the corresponding terminal board connector. Visual diagnostic support is provided through indicator LEDs, making it easy to monitor operational status at a glance.
The IS220PHRAH1B incorporates a functionally compatible BPPC processor board. This board is supported in ControlST* software suite versions V04.07 and later.

Q&A: 1. How to install IS220PHRAH1B? (1) First, securely mount the SHRA terminal board in place. (2) Take one PHRA I/O pack and plug it directly into the DC-62 pin connector on the SHRA terminal board. (3) Use the threaded studs next to the Ethernet ports to mechanically fasten the I/O pack. These studs slide into a mounting bracket that’s specific to the type of terminal board you’re using. Make sure to adjust the bracket’s position so that no right-angle force is applied to the DC-62 pin connector between the I/O pack and the terminal board. You’ll only need to make this adjustment once during the product’s entire service life. (4) Connect one or two Ethernet cables, depending on your system configuration. The I/O pack will work with either port. If you’re using dual connections, the standard practice is to connect ENET1 to the network associated with the R controller. (5) To power the pack, plug in the connector located on the side of the I/O pack. There’s no need to turn off the power to the cable before plugging it in—this is because the I/O pack comes with inherent soft-start capability that controls current inrush when power is applied.
(6) Finally, use the ToolboxST* application to configure the I/O pack as required.
