WTZ4 Series
PID Temperature Controller

Download

The WTZ4 Series of PID controllers offer front panel selection of all operating functions except output type. Programming flexibility includes selection of a second temperature set value, sensor type, and all PID function parameters. Another unique selectable feature is fast or slow PID response. When set in the slow response (PIDS) mode, very little, if any overshoot will occur. If selected, Auto-tune control will monitor the system output response and after 3 response cycles will automatically calculate and replace the PID constants with optimal process control parameters. Two independent alarm outputs, each with 9 alarm mode types, can be programmed for automatic or manual reset. If you desire ramp up or ramp down to SV all models have that capability. This feature will allow the WTZ4 to be used in hot runner applications.

	Function options are all front panel selectable including sensor input. Only input must be ordered by model
	2 temperature set values can be entered. Operator can then manually select between the two separate set values.
	Fast or slow PID response selectable — In slow response overshoot eliminated.
	2 independent alarm outputs, each with 9 operating modes
	Universal Input: 100-240 VAC 50/60 Hz, 100-240 VDC
	Powerful but inexpensive
	Diverse outputs like Relay, SSR driver, and 4-20mA analog.
	Multi-input type selectable 15 kinds of input modes
