GE IS200TPROH2C
Product Name: Mark VIe HART-Enabled Analog I/O Module (PHRA I/O Pack)
Product Introduction: The IS200TPROH2C is a HART-enabled analog input/output module developed by General Electric for the Mark VIe control system. It serves as a critical connection point, providing electrical interfaces between one or two I/O Ethernet networks and analog input/output terminal boards. It combines a standardized processor board (common to all Mark VIe distributed I/O packs) with a customized acquisition board optimized for analog input functionality.

Working Principle: The PHRA I/O pack inserts directly into the selected terminal board. The dual Ethernet ports connect to the Mark VIe I/O network(s), providing redundant communication paths. The customized acquisition board conditions and digitizes up to 10 analog input signals. For current loop inputs, the voltage across the load terminal resistor on the terminal board is sensed and measured. The two 4–20 mA outputs are driven by the DAC stage. In HART mode, the module modulates/demodulates HART signals on top of the 4–20 mA loop, relaying digital HART frames between the field instrument and the host AMS via the Ethernet network. The 150 MHz-class processor handles scaling, linearization, and HART protocol stack.
Installation Requirements:
-
Securely install the selected terminal board in its desired position
-
Insert a single PHRA I/O pack directly onto the terminal board connector
-
Use the threaded bolts near the Ethernet port to secure the I/O pack to the terminal board’s mounting brackets
-
Adjust the bracket position to prevent right-angle force on the DC-62 pin connector (one-time adjustment)
-
Connect one or two Ethernet cables; in dual configuration, typically ENET1 connects to the R controller-associated network
-
Insert the side power connector to energize the pack
Usage Precautions:
-
Ensure the DC-62 connector is fully seated before securing bolts to avoid pin bending
-
Verify network redundancy cabling matches the controller topology
-
Use the infrared port for deep diagnostics — do not attempt to remove the conformal coating if present
-
Monitor LED indicators for power and channel health
