Watlow’s Series 104 is an economical open board, on-off
temperature controller with a thermocouple or RTD sensor
input. Installation and setup of the control is simple and
easy.
The Series 104 offers setpot options including integral
or fixed set point. Factory selectable options include electro-
mechanical relay, SSR or switched dc output, dual scale,
and heat or cool control mode.
