IS420UCSBH1A | GE Electric Universal Controller Safety Module
Product Description
The GE IS420UCSBH1A is a high-performance Universal Controller Safety Module from the Mark VIe Series, engineered for distributed control and safety management in critical industrial processes. It integrates triple-redundant processing for SIL 2 applications, executing real-time logic, sequencing, and I/O interfacing to protect turbines, compressors, and other high-value assets.
Key Features
- Advanced Processing: Triple 32-bit processors with hardware voting logic (SIL 2 certified).
- Modular I/O: Supports up to 12 expansion modules (digital/analog/safety-rated).
- High-Speed Communication: Dual 100 Mbps Ethernet ports with IEEE 1588 time synchronization.
- Robust Diagnostics: Continuous health monitoring, event logging (1,000+ records), and predictive failure alerts.
- Environmental Resilience: Operates in -40°C to +85°C environments with 95% non-condensing humidity.
- Cybersecurity: Supports TLS/SSL encryption and role-based access control.

Series Overview
Part of the GE Mark VIe Distributed Control System, the UCSB series enhances scalability for complex safety loops. The IS420UCSBH1A variant includes:
- IS420: Mark VIe series identifier (enhanced processing).
- UCSB: Universal Controller Safety Base unit.
- H1: Hardware revision (extended temperature range).
- A: Standard configuration with SIL 2 compliance.
Applications
- Power Plants: Gas/steam turbine control, anti-surge protection.
- Oil & Gas: Safety instrumented systems (SIS) for pipelines and refineries.
- Chemical Processing: Reactor temperature/pressure safety interlocks.
- Renewables: Wind turbine pitch control and grid synchronization.
- Marine: Dynamic positioning and engine safety shutdown.
Functional Role
The IS420UCSBH1A manages critical safety functions by:
- Monitoring sensors (e.g., vibration, temperature, pressure).
- Executing configurable logic to trigger shutdowns if thresholds are breached.
- Communicating with HMIs/SCADA via OPC UA or Modbus TCP.
- Storing event sequences for compliance audits and root-cause analysis.
Why Choose the IS420UCSBH1A?
- Scalability: Modular I/O expansion for evolving system needs.
- Precision: ≤1 ms response time for safety-critical trips.
- Interoperability: Integrates with Mark VIe, Proficy®, and third-party PLCs.
- Lifecycle Support: 20+ years of firmware compatibility and GE service coverage.
