DIN Package  
with DeviceNet™  
The Watlow SERIES D8 is a powerful line of controllers that  
combines performance and flexibility with compact design.  
Compliance with the Open DeviceNet™ Vendors Association  
Features and Benefits  
PID control of up to eight loops  
Minimizes panel space per loop  
Reduces installation time  
(ODVA) and Semiconductor Special Interest Group (SIG)  
standards means this controller is easy to integrate into  
systems with DeviceNet™ networks on Controller Area  
Network (CAN).  
Increases reliability, fewer parts mean fewer failures  
Complies with ODVA and Semiconductor SIG  
specifications for DeviceNet™ on CAN  
Integrates with other DeviceNet™ nodes and software  
Provides sealed micro connector for minimal installation  
time and footprint and maximum reliability  
The four and eight loop versions of SERIES D8 controllers  
provide complete control solutions for a broad range of  
applications. Support for multiple types of sensor inputs  
including thermocouples, RTDs, linear voltage and current  
is also available.  
Simplifies setup with rotary switches for baud rate and  
node address  
Each loop can be individually configured for on-off control or  
PID control. Loops can also be combined to achieve cascade,  
ratio or differential control. Process variable retransmit and  
remote analog set point are included.  
Simplifies commissioning and troubleshooting a network  
with network and module status LEDs  
Menu-guided operation with full text prompts  
Allows quick setup of the controller  
Simplifies operation  
The SERIES D8 controllers are UL® and C-UL® listed, meet  
the requirements of the European Community EMC Directive  
and carry the CE mark.  
Context-sensitive, on-screen help  
Saves time  
Reduces learning curve  
Advanced control utilities  
Auto-tune optimizes control with minimal effort and  
expertise  
Cascade minimizes overshoot and improves control in  
systems with excessive thermal lag  
Ratio and differential enhance control in areas where the  
relationship between two or more loops is paramount
