The General Electric UR6CH is a digital I/O module designed for the UR series protection relay system, providing reliable output control for industrial and power automation applications. It is used to convert relay logic signals into actionable commands for external auxiliary equipment, ensuring stable system coordination in real-time operations.

The UR6CH features 8 Form-C (SPDT) digital outputs, allowing flexible switching between normally open and normally closed contacts. Each output supports up to 250V AC/DC, making it suitable for controlling devices such as circuit breakers, alarms, and indicator systems. Its robust design ensures consistent performance in demanding electrical environments.

With an H-type 19-inch horizontal installation structure, the UR6CH integrates easily into standard rack systems used in substations and industrial control panels. It is fully configurable through EnerVista UR Setup software, enabling efficient setup and maintenance. This makes the UR6CH a dependable expansion solution for enhancing the control capability of UR series relay systems.

The UR6CH General Electric Digital I/O Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The General Electric UR6CH is an essential digital I/O expansion module within the GE Multilin UR protection relay platform. It is designed to enhance system communication between protection relays and external auxiliary equipment, enabling efficient and reliable control logic execution. In modern electrical systems, the UR6CH plays a key role in bridging protection decisions with physical switching actions.

The UR6CH provides 8 Form-C (SPDT) digital outputs, each featuring a changeover contact structure with normally open (NO) and normally closed (NC) terminals. This configuration allows flexible switching behavior for different control requirements. With a contact capacity supporting up to 250V AC/DC, the UR6CH ensures stable performance in demanding industrial and utility environments where reliable signal switching is critical.

From an installation perspective, the UR6CH adopts an H-type horizontal design, making it compatible with 19-inch horizontal chassis slots. This structure supports efficient rack integration and simplifies system expansion. The module is fully configurable through EnerVista UR Setup software, allowing engineers to adjust logic behavior and output settings according to site-specific requirements.

In terms of environmental adaptability, the UR6CH operates within a temperature range of -25°C to +70°C, ensuring stable performance under typical substation and industrial plant conditions. It also complies with major international standards including IEEE C37.118, IEC 61850, CE, UL, and CSA, confirming its suitability for globally certified power automation systems.

When compared within the same UR series ecosystem, such as the UR8LH CT/VT input module, the UR6CH focuses on output execution and control actions, while the UR8LH is responsible for signal measurement and acquisition. This distinction highlights the UR6CH’s role as an action-oriented module, enabling decisive switching commands based on relay logic.
