2 Watlow MicroDIN Quick Start Guide
Introduction to the MicroDIN Controller
The Watlow MicroDIN controller is a DIN rail-mounted, temperature controller.
It uses one input and two outputs, network connections and dozens of parame-
ters to satisfy a broad variety of control needs.
The single input can use either a thermocouple or RTD sensor. The single con-
trol output provides an open collector or switched dc output signal for a power
switching device with a DC input. The single alarm output is an electromechani-
cal relay. The network connections allow as many as 32 controllers to be config-
ured and monitored from a single personal computer.
You can configure, operate and monitor the MicroDIN almost entirely from a
PLC or personal computer via a serial connection using RJ-11 jacks. Indicator
lights on the face of the controller monitor error states, power, communications
activity and output activity.
