The Sensaphone SCADA 3000 Universal Input Module is an optional component for use with the Sensaphone SCADA 3000 system. The input channels are identical to those included on the Sensaphone SCADA 3000 main unit.
The Universal Input Module features 8 channels that can be configured to interface with several different types of sensors and transducers, including: Normally Open/Normally Closed dry contacts, digital logic, run time accumulation, 0-5V analog, 4-20mA analog and 10K thermistor (oC & oF). The module features 12-bit resolution, differential inputs, 24V supply for powering 4-20mA loops and low-power operation.
Each input is protected by a 1500 Watt transient suppressor. In addition, a microprocessor watchdog circuit is integrated to maintain system reliability, LED indicators are provided to show system power and module operation via a blinking pulse LED.
The Universal Input Module provides eight inputs that can be configured for use with a variety of sensors. Each input has a configuration jumper that conditions the signal appropriately based on the attached sensor. The module continuously reads the signal at each input and communicates the value back to the SCADA 3000 via the 4-wire communications bus.
The SCADA 3000 will allow you to set customized tables to scale the input accordingly. The value of each input can be used in the ladder program or C-program to perform control functions. You may even choose just to monitor or datalog an input and activate alarms based on high and low set-points. The SCADA 3000 User's Manual provides information on how to take advantage of all the possibilities. Listed below are some of the possible applications for the Universal Input Module:
