IS420UCSCH1A GE Vernova Mark VIe Controller
Application-specific controller for turbine and balance-of-plant control installations, with embedded PROFINET gateway functionality for supported PROFINET I/O devices.
Controller architecture
The IS420UCSCH1A is a standalone, quad-core controller using QNX Neutrino real-time operating-system technology. Its application-specific software runs control logic for supported Mark VIe installations.
The controller operates as a single module, uses convection cooling and requires no battery, fan or hardware jumper settings. Its flash memory supports software updates appropriate to the installed application.
Technical Specifications
| Controller Platform | Mark VIe UCSCH1x |
| Processor | Quad-core AMD G-Series, 1.2 GHz |
| Memory | 4 GB DDR3-1333 SDRAM |
| Control Software | ControlST; the UCSCH1x family is available from ControlST V07.01. The required release depends on the installed application. |
| Programming | Control blocks with analog and discrete blocks; Boolean logic represented in relay ladder diagram format. |
| Data Types | Boolean; 16-bit signed and unsigned integers; 32-bit signed and unsigned integers; 32-bit and 64-bit floating-point values. |
| Dimensions (H × D × W) | 168 × 150 × 55 mm (6.61 × 5.90 × 2.17 in) |
| Dimensions with Mounting | 204 × 152 × 55 mm (8.03 × 5.99 × 2.17 in) |
| Weight | 1,327 g (46.8 oz) |
| Cooling | Convection; installation airflow clearances must be maintained. |
| Operating Temperature | −40 to +70 °C, measured 25 mm from the controller. Mounting and airflow conditions affect the permitted operating envelope. |
| Storage Temperature | −40 to +85 °C |
Additional Specifications, Interfaces, Power Connection & Installation Requirements
Additional specifications
| Humidity | 95% non-condensing |
| Input Power | 18–30 V DC; nominal 18 W, maximum 30.8 W. |
| Input Protection | Non-replaceable 4 A, 125 V DC-rated fuse; reverse-polarity protection provided. |
| Reliability Reference | MTBF at 30 °C: 414,248 hours for the IS420UCSCH1 controller family specification. |
Communication interfaces
| IONet | Three Ethernet interfaces for communication with Mark controls I/O packs and controllers. UCSCH1A supports the IONet arrangements used by Simplex, Dual and TMR controller configurations. |
| Embedded PROFINET Gateway | The UCSCH1A provides embedded PROFINET gateway functionality for supported PROFINET I/O devices, including RSTi-EP Slice I/O. |
| UDH / LAN | Ethernet interface used for communication with the ToolboxST application. |
| Other interfaces | Additional Ethernet, USB, serial and display interfaces are described for the UCSC family. Confirm the individual connector labels and intended use on the installed hardware before connecting equipment. |
DC power connector
| Connector | 3-pin Phoenix Contact MC 1,5/3-STF-3,81, part number 1827716. |
| Pin 1 | Ground |
| Pin 2 | Negative (−) |
| Pin 3 | Positive (+) |
| Wire Size | 28–16 AWG |
| Screw Torque | 0.23 N·m (2 in-lb) |
The controller case is bonded to the power-supply negative. Reversed input polarity is protected against damage, but the controller will not power up.
Mounting and thermal clearance
| Mounting Position | Mount vertically using the two mounting screws on the mounting base. |
| Airflow | Keep the cooling fins unobstructed. |
| Clearance Above / Below | Minimum 100 mm (3.94 in). |
| Side-by-Side Controllers | Minimum 50 mm (1.97 in) spacing between parallel-mounted UCSC controllers to achieve the full temperature rating. |
| Temperature Reference Point | Operating-temperature limits are specified at 25 mm from any point on the controller. |
Application & Failure Scenarios
Turbine and plant control
Used for application-specific logic in supported wind-turbine, gas-turbine, steam-turbine and combined-cycle power-generation control systems.
PROFINET I/O communication
Relevant when troubleshooting a UCSCH1A-based installation involving supported PROFINET I/O devices. Check gateway configuration, network connections and controller diagnostics before replacing hardware.
Controller outage or restart
A controller fault can interrupt its assigned control function and delay equipment recovery. Review alarms, power input, airflow and network status to distinguish a controller failure from an external system issue.
Supply & Service
Testing: Inspection and testing scope is confirmed for the specific unit before order commitment.
Packaging: Packaging condition and requested product condition are confirmed before dispatch.
Returns, DOA & Warranty: Obtain written confirmation of return eligibility, DOA notification requirements, warranty duration and coverage in the quotation or order terms.
