Overview
1.2 Watlow MicroDIN1.2 Watlow MicroDIN
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
parameters to satisfy a broad variety of control needs.
The single input can use either a thermocouple or RTD sensor. The single
control 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
electromechanical relay. The network connections allow as many as 32
controllers to be configured 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.
