GE IS220PHRAH1A HART-Enabled Analog I/O Pack

FAQ

Q1: What is GE IS220PHRAH1A?
A: IS220PHRAH1A is a HART-enabled analog I/O pack designed for the GE Mark VIe turbine control system. It provides analog signal acquisition, analog outputs and HART communication.

Q2: How many I/O channels does IS220PHRAH1A have?
A: It provides 12 analog channels in total: 10 analog inputs and 2 analog outputs.

Q3: What input signals can IS220PHRAH1A accept?
A: Analog inputs 1–8 can be configured for ±5 VDC or 4–20 mA, while inputs 9–10 can be configured for ±1 V or 4–20 mA.

Q4: Does IS220PHRAH1A support HART communication?
A: Yes. The module is specifically designed as a HART-enabled analog I/O pack and can relay HART messages between compatible field devices and an asset-management system when operating in 4–20 mA mode.

Q5: Which terminal boards are compatible with IS220PHRAH1A?
A: The approved accessory terminal boards are IS200SHRAH1A and IS200SHRAH2A. GE documentation explicitly identifies these boards for use with IS220PHRAH1A.

Q6: What power supply does IS220PHRAH1A require?
A: The module uses approximately 28 VDC nominal power, with a specified range of 27.4–28.6 VDC and a maximum supply current of 0.5 A.

Q7: What are the dimensions and weight of IS220PHRAH1A?
A: A commonly listed physical size is approximately 82.6 × 41.9 × 121 mm, with a reference weight of about 0.5 kg. Supplier measurements can vary slightly depending on whether connectors and mounting hardware are included.

Q8: Is IS220PHRAH1A used in redundant configurations?
A: The IS220PHRAH1A is intended for simplex operation. It is installed on the appropriate Mark VIe terminal board and communicates with the control system through the Mark VIe IONet architecture.
