IS410TRLYS1B | GE Electric Safety Relay Module
Product Description
The GE IS410TRLYS1B is a High-Integrity Safety Relay Module for GE’s PACSystems RX3i PLC platform, providing SIL3/Category 4 (ISO 13849) safety control for critical machinery shutdown systems. It executes redundant safety logic with diagnostic coverage (DC ≥ 99%) to prevent hazardous failures in emergency stop (ESD), fire/gas, and process safety applications.
Key Features
- Dual-Channel Safety: TÜV-certified architecture (2oo2D voting)
- Integrated Diagnostics: Continuously monitors relay health (coil/signal faults)
- Fail-Safe Design: Forces outputs to safe state on power loss/error
- Hot Swappable: Replace without system shutdown
- CyberSecure: IEC 62443-3-3 compliant firmware signing
- Visual Status: Dual-color LEDs (green/red per channel)

Series Overview
Part of GE’s RX3i Safety-on-CPU Series:
- IS410TRLYS1B: Relay output module (4 channels)
- IS416MSV2S1B: 16-input safety monitor
- IS420ESWBH3A: Ethernet safety switch
- IC695SAI116: Analog input safety module
Applications
- Emergency Shutdown (ESD): Oil/gas wellhead control
- Burner Management: Furnace flameout protection
- Robotic Cells: Collaborative robot safety interlocks
- Press Lines: Light curtain monitoring
- Turbine Overspeed: Mechanical backup tripping
Functional Role
- Hazard Mitigation: De-energizes equipment within 50ms of safety trigger
- Fault Masking: Prevents single component failure from causing unsafe state
- Health Reporting: Sends diagnostics to CPU via backplane (SNP-X protocol)
- Cross-Domain Safety: Interfaces with non-SIL sensors via IS416 input modules
Why Choose IS410TRLYS1B?
- Certified Integration: Pre-validated with RX3i CPUs (e.g., IC695CPE310)
- Lifecycle Management: 20-year product support commitment
- Space Savings: Replaces 4 standalone safety relays (1-slot 160mm module)
- Proof Test Interval: 100 years per exida FMEDA report
- Legacy Support: Compatible with VersaMax I/O bases
