Series 8 Controllers

Temperature and High Limit Controller

Series 8 1-4 DIN front view

The Series 8 is SSi’s affordable line of process and high limit controllers. These products are used for many thermal processing and indicating applications. The Series 8 has universal inputs with relays and analog outputs allowing for versatility and a wide range of monitoring or controlling applications. With 3 options for sizes (1/16, 1/8 and ¼ DIN), the panel mount unit offers high accuracy universal inputs for PID control and high limit protection.
