While Proteus includes individual relays, using a dedicated module library offers several advantages: 4 channel relay module library for proteus new

This paper presents the complete process of designing, creating, and validating a custom 4-channel relay module library for use in Proteus Design Suite. Standard Proteus libraries contain individual relay components (e.g., RELAY ), but lack the integrated 4-channel opto-isolated module commonly used in Arduino, Raspberry Pi, and industrial control projects. This work details the schematic symbol creation, PCB footprint design (if applicable), spice model integration, and practical simulation examples. The resulting library allows engineers to simulate high-voltage AC/DC load control with proper isolation representation before hardware implementation. | Pin Number | Pin Name | Type
