Honeywell XS824-25 Panel Bus I/O Modules

The UDC3500 is a microprocessor-based stand-alone controller. 

It combines a high degree of functionality and operating simplicity in a 1/4 DIN size controller. 

This instrument is an ideal controller for regulating temperature and other process variables in numerous heating and cooling applications, 

as well as in metal working, food,pharmaceuticals, semiconductor, testing and environmental work.

The UDC3500 monitors and controls temperatures and other variables in applications

such as environmental chambers, plastic processing machines, furnaces and ovens, and packaging machinery.

Alarms

Up to four electromechanical alarm relays are available to activate external equipment

when preset alarm setpoints are reached. Each of the four alarms can be set to monitor

two independent setpoints. Each alarm setpoint can be either high or low alarm. The

alarm type can be selected to be either of the inputs, the Process Variable, Deviation,

Output, Shed from communications, PV rate of change, or to alarm on manual mode

activation or a Current Output Open failure. It can also be used as an On or Off event at

the beginning or end of a Ramp/Soak segment. An individual alarm hysteresis setting is

provided for each relay and these are configurable from 0 to 100% of range.

 Alarms can be configured as latching or non-latching. continued

 Alarm blocking is also available which allows start-up without alarm energized

until after it first reaches the operating region.

 PV rate of change alarm.

 Loop break alarm.

 Timer output reset.

 Diagnostic Alarm
