1 Overview 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.

Mounting the Series PD Figure 4a — Mounting 1. Push unit in and down to catch rail hook on top of rail. 2. Rotate bottom of unit toward rail. 3. Rail clasp will audibly “snap” into place. If the Series PD does not snap into place, check to see if the rail is bent. Removing the Series PD Figure 4b — Removal 1. Press down on back of the Series PD until the bottom hook clears the rail. 2. Rotate bottom up and away from rail.
Series PD Connector Locations Two connectors on the bottom of the unit provide connection points for the input power, inputs and outputs. These connectors are removable and each terminal position is numbered. The RJ-45 connector is located on the top of the Series PD to allow connection to an Ethernet network.

3 Indicator Lights The Series PD controller may have up to nine LED indicator lights to help you monitor the status of input power, Ethernet functions, input errors and outputs status. These LEDs can provide a quick visual indication of basic controller functions. Power Green light stays lit when the power is on. • If not lit or flashing, check your power source. Ethernet Link: Green light is lit if the Ethernet cable is correctly wired and connected to a 10BaseT port.
4 Ethernet Communications Network security is a critical issue for any network. Be sure to work with your network administrator to ensure that you follow best security practices to ensure a secure network environment. Here are some items to consider when installing Ethernet based controls on any network. • Use private IP addresses. • Separate the process network(s) from business network(s). • If external access is required, then have a single point of access to the process network.
