DCP200 Profile Controller & Recorder - Product Manual

Triac

A small internal solid state relay, which can be used in place of a mechanical relay in applications switching low power AC, up to 1 amp. Like a relay, the output is time proportioned, but much faster switching cycle times are also possible, leading to superior control. As a solid-state device, a Triac does not suffer from contact degradation when switching electrical currents. A snubber should be fitted across inductive loads to ensure reliable switch off the Triac. A triac cannot be used to switch DC power.

Also refer to: Cycle Time, Relay, SSR and Time Proportioning Control.

USB Menu

If the USB option is fitted, the USB Menu can be accessed from the Main Menu. This menu is lock code protected.

The USB Menu allows the user to read or write files to a USB memory stick. The current configuration of the instrument can be downloaded to the stick or the instrument can be completely reconfigured using a pre-stored file that has been downloaded earlier, created using the PC software, or even taken from another instrument.

If the Data Recorder option is present, the recordings can be downloaded to the stick for transport to the users PC for analysis. If the Profiler option is present, profiles can be downloaded to the stick or upload to the instrument using a pre-stored file that was downloaded earlier, created using the PC software, or even taken from another instrument.

Refer to the USB Menu information in the Configuration & Use section.

Valve Motor Drive Control (VMD)

This instrument can only control modulating valves that have a valve positioning circuitry that adjusts the valve position according to the level a DC linear mA or voltage output signal. Such valves normally require PI control instead of full PID.

Motorised modulating valves that do not have this type of circuit require special Valve Motor Drive controllers which have a “Three Point Stepping” control algorithm.

Solenoid valves can also be controlled using the standard PID algorithm as they behave in a similar way to relays, having just two states, open or closed.

Also refer to: Control Deviation, Linear Output, Modulating Valve, PI Control, PID, Relay, Solenoid Valve, and Three Point Stepping Control.

VDC

This stands for Volts DC. It is used in reference to the linear DC Voltage input ranges. Typically, these will be 0 to 5V, 1 to 5V, 0 to 10V or 2 to 10VDC. Linear outputs can also provide DC voltages.

Also refer to: Auxiliary Input, Input Range, Linear Input, Linear Output, mADC and mVDC..

VMD
