The fully field configurable Chromalox model 1603E 1/16 DIN controller combines advanced hardware design and sophisticated electronic control technology into a compact, reliable 1/16 DIN package. Easy to Install and Operate The 1603E plug-in design requires only panel cutout, instrument mounting, setpoint adjustment to set up. Additional parameters are programmed via the front pushbuttons via the Configuration Port.

Configuration Port

Each 1603E has a Configuration Port for remote set up of the controller. This feature allows the 1603E to be programmed from a PC without any connections for power.

Special Control Features
• Heat/Cool Control Features Selection of Cooling Medium and Overlap
• Soft Start-Timed Output Power Limit on Start-Up. Allows a “warm up period” to protect the process and avoid thermal shock on start up
• Control Output “Turn Off” Via Pushbuttons if used during setup or controller becomes a monitor
• Programmable offset of Process Temperature

SMART Self-Tuning
The model 1603E meets the application needs of operators with or without skills in temperature processes and PID control.
SMART self-tuning automatically adjusts the controller to rapidly respond to all process changes. Sophisticated control features include:
• Start-up and continuous in-process tuning
• Continuous self-tuning without artificial upset
• Proven maximum suppression of overshoot

During Start-Up the SMART self-tuning function calculates the control parameters to optimize the rise to setpoint.


During Process SMART updates the control parameters as needed to respond to setpoint changes or a log change.

Configuration Port & Kit

The 1603E can be connected to the remote Configuration Kit, CNFG-10000. This method of configuration is ideal for OEM’s for quick setup and for resellers to easily program a controller for the specific needs of a customer.

Setup is simple:
1. Remove the 1603E from the shipping box or from the case.
2. Snap the push pin connector into the side of the 1603E.
3. Connect the 9 pin connector to the PC’s RS232 port.
4. Connect the Power Supply.
5. Download the setup.

The controller doesn’t need power. WIRING is Not required. The configuration software can download all the parameter. Special setups can be saved for future downloads.
The Configuration Kit CNFG-10000 consists of the following:
• Configuration Software Windows Based CDROM
• Hardware Connection Assembly
• Power Supply with Standard Wall Plug
The Hardware Connection Assembly has a 9 Pin RS232 connector for hook up to a PC COM Port, a specially designed connector for connection to the 1603E Configuration Port and a connection for the power supply.
