The Series PD controller is a DIN rail mounted, general purpose industrial PID temperature/
process controller. The Series PD is available in single and dual channel versions and features an
embedded web server to provide an easy to use interface for configuration and monitoring of
processes. The controller also features several popular communications protocols to facilitate easy
integration into most existing process management systems.
The Series PD accepts thermocouple, RTD and process signal control inputs and also features
auxiliary digital inputs or optional current transformer (CT) inputs. Up to four control or event
(alarm) outputs can be selected on either the single or dual channel versions.
Advanced features of the Series PD controllers include internal datalogging of key control pa-
rameters, INFOSENSE-P™ sensor technology, heater burn out detection and an enhanced control
algorithm.
The SERIES PD controller is backed by a three-year warranty from Watlow Winona and is
UL® 508, C-UL®, CSA and CE approved.
