Logic Level / TTL To Relay / Volt Free Contact Converters

Lee-Dickens logic-level and TTL converters are designed to interface low-level electronic control signals with relay-operated equipment. They convert logic or TTL inputs into relay outputs or volt-free contacts, allowing electronic systems, controllers and monitoring equipment to operate alarms, interlocks and other external devices safely and reliably. These converters are useful where different signal types need to be connected without redesigning the existing control system.
