80C552 Timer Power Supply Module
Power Supply and Solid-State Relay for the 80C552 Timer Development Module
This is simply a transformer, bridge rectifier, capacitor and 7805 voltage regulator used to power the 80C552 Timer Development Module.
The Timer Module controls it's 'load' through the Solid-State Relay (SSR) contained on this Power Supply Module. A dual-color LED (Red & Green) indicates the current status of the 'load'. When the SSR is off, the load is off, and the LED is RED. When the SSR is on, the load is on, and the LED is GREEN.
A 10pin header connects a keypad to the timer module, and is setup as a 5x4 key matrix. We also sell the actual keypads since we ended-up with some leftovers. All other ports are presented on the four 6pin Molex headers. An LM34DZ is also built in for your temperature measurements.
Full Schematics are supplied.
WARNING: This module has exposed 115VAC and should be fused, and mounted in a proper box!
