S E R I E S D 8 C O N T R O L L E R
The Watlow D8 series is a powerful line of controllers that
combines performance and flexibility with compact design.
Compliance with the ODVA and Semiconductor SIG standards
means this controller is easy to integrate into systems with
DeviceNet™ networks on CAN (Controller Area Network).
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.
Each loop can be individually configured for on-off control or
PID control. Loops can be combined to achieve cascade, ratio
or differential control. Process variable retransmit and remote
analog set point are included.
The Series D8 controllers are UL
®
and C-UL
®
listed, meet the
requirements of the European Community EMC Directive and
carry the CE mark.

Features and Benefits
PID control of up to eight loops
• Minimal panel space per loop
• Reduced installation time
• More reliable, fewer parts mean fewer failures
Complies with ODVA (Open DeviceNet™ Vendors
Association) and Semiconductor SIG (Special Interest
Group) specifications for DeviceNet™ on CAN (Controller
Area Network)
• Integrates with other DeviceNet™ nodes and software
• Sealed micro connector minimizes installation time and
footprint while maximizing reliability
• Rotary baud rate and node address switches simplify
setup
• Network and module status LEDs simplify commissioning
and troubleshooting a network
Flexible, easy-to-use interface
• Easy setup with menu guided, full-text prompts
• Context-sensitive, on-screen help saves time
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
