Connecting Loads to Digital Outputs on DMC-1800 Controllers

Learn how to interface high-current loads like solenoids and heaters with DMC-1800 digital outputs using solid-state relays. This application note covers TTL output specifications, current limitations of 74ACT273 buffer ICs, and proper wiring configurations for both standard controllers and extended I/O setups with DB-14064 expansion boards. Includes practical examples of sinking circuit designs and external power supply requirements for reliable load switching.
