4 Channel Relay Module Library For Proteus New [new] Jun 2026

For years, Proteus users had to simulate relays by placing individual components—coil, transistor driver, diode, and resistors—turning a simple schematic into a cluttered mess. The introduction of the dedicated library (often found in newer versions or as an imported library in 8.x+) has streamlined the design process significantly.

| Test | Condition | Expected Result | Observed | |------|-----------|----------------|----------| | Logic Low | INx = 0V | Relay coil energized, COM to NO | Pass | | Logic High | INx = 5V | Relay de-energized, COM to NC | Pass | | Power Supply | VCC = 5V, JD-VCC = 5V | All channels functional | Pass | | Isolation | Separate JD-VCC = 9V | Relays switch with higher force | Pass | | Transient | Square wave 10Hz | No contact bounce (ideal model) | Acceptable for digital sim | For years, Proteus users had to simulate relays
