The MSD 7564 is a four-channel solid-state relay with 20A continuous and 50A instantaneous output per channel. It has no mechanical contacts and can be triggered by power supply or ground. It also features built-in over-temperature and short-circuit protection and LED diagnostics.

Specification

• Original Part Number (MPN): 7564
• Type: Solid State Relay Module (No Mechanical Contacts)
• Number of channels: 4 independent channels
• Current per channel: 20 A continuous; 50 A for a maximum of 8 seconds.
• Total output: 80 A continuous / 200 A instantaneous
• Power supply voltage: 5 – 20 V
• Triggering method: Single-wire trigger per channel, can be connected to 12V or ground.
