Overview
Minco’s CT425 Temperature Controller is a PID
temperature controller capable of reading two
independent temperature sensors (RTDs). By utilizing
an internal solid state relay, logic voltage output,
and internal mechanical relay, the controller is fully
configurable. Simply connect the CT425 to a laptop or PC
to configure.
Features
• Flexible configuration for:
• Inputs
• Utilize one or two Platinum RTDs
• Choose 100 or 1000 ohm RTDs
Outputs
• Utilize up to three outputs
• Solid state relay
• Logic voltage
• Mechanical relay
• Choose control type
− PID
− On/Off (mechanical relay only)
− Alarm
• USB and a user-friendly software package allow for easy
setup and use
• 32-bit microprocessor executes both PID loops
simultaneously at individually configurable rates up to 25
times/second
• High current capacity internal switching
• Electrically isolated switching outputs increase high
voltage safety
• AC powered models perform zero-cross detection to
reduce switching noise
• LED indicators provide a quick confirmation of correct
sensors input operation
Programming
All configurations are performed through the Windows
application. The CT425 may be powered through USB if
desired. This allows the user to configure the unit, or simply
become familiar without having to connect separate power.
Applications
The CT425 is designed for a variety of applications that
include heating and cooling of equipment or processes. The
CT425’s versatility makes it ideal to use as an off-the-shelf
prototyping tool or as an economical controller for small to
medium volume applications. Moreover, the CT425’s modular
design provides the platform for fast and cost-effective custom
designs for medium to high volume applications.
Bluetooth Low Energy
A Class 2 Bluetooth Low Energy (BLE) modem has been
included on the CT425 to allow wirelessly viewing of
temperatures and changing of set points using an Android or
Apple smartphone. The primary purpose of this is to monitor
real-time operation of the CT425 without using a PC because
the CT425 does not have a display.
Datalogging
The on-board data-logger is active as long as the CT425 is
powered. It does not affect any other function and therefore, is
completely transparent to the user. The logger uses the circular
buffer concept which means that once the entire available
memory is filled with samples, the oldest data is overwritten
with new data. This will store a number of the most recent
samples, with the older samples overwritten with newer data.
