GE IS410TRLYS1B Product Specification
1. Product Overview
The GE IS410TRLYS1B is a high-reliability 16-channel electromechanical relay output module designed for GE’s Mark VIe and Mark VI distributed control systems (DCS). Specialized in converting digital control signals into discrete relay actions, it serves as a critical interface component between the DCS and industrial field devices such as valves, motors, and alarms. Widely applied in power generation, oil & gas, and industrial automation, this module ensures reliable execution of control commands, supporting safe and efficient operation of mission-critical systems.
Compliant with international standards including IEC 61508 (SIL 2), IEC 61810-1, and EN 61326-1 (EMC), the IS410TRLYS1B features robust galvanic isolation, high switching durability, and built-in diagnostic functions. It integrates seamlessly with GE’s Turbine Control Studio and CIMPLICITY software, providing engineers with a user-friendly and cost-effective solution for discrete control in industrial environments.

3. Key Features
3.1 High-Density Reliable Switching
Equipped with 16 SPDT (Form C) relays, the module offers flexible switching options (normally open/normally closed) for diverse field devices. The 10 A switching capacity supports heavy-duty loads like industrial motors, while the ≥10 million mechanical life ensures long-term reliability in high-cycle applications such as turbine auxiliary system control.
3.2 SIL 2 Safety & Diagnostic Capabilities
Certified to IEC 61508 SIL 2, the module integrates relay status monitoring (contact feedback) and fault detection (e.g., coil failure, over-temperature). This real-time diagnostic data is transmitted to the DCS, enabling predictive maintenance and ensuring safe operation in critical scenarios like emergency shutdown systems.
3.3 Robust Isolation & EMI Protection
2.5 kV DC galvanic isolation between channels and backplane prevents electrical interference and cross-talk, protecting the DCS from field-side voltage surges. Compliance with EN 61326-1 ensures immunity to electromagnetic interference (EMI), maintaining stable performance in noisy industrial environments like power plant control rooms.
3.4 Seamless DCS Integration
Designed for plug-and-play compatibility with GE Mark VIe/VI DCS, the module is fully supported by GE’s engineering software. Pre-configured function blocks simplify programming, while standardized communication protocols ensure fast commissioning and reliable data exchange with the central controller.
