The Watlow Series 103 is a DIN rail mount, on-off
temperature controller with a thermocouple or RTD
sensor input. The DIN rail mounting offers quick and
easy installation with the use of simple hand tools. The
controller may also be flush mounted.
The Series 103 can be factory configured as either a
heat or cool output. Output types include electromechani-
cal relay, solid-state relay or open collector output.
The Series 103 has an LED for output status
indication and can be ordered with an integral, adjustable
set point or a fixed set point.
