Keithley 3750 Multifunction Control
The Keithley 3750 Multifunction Control redefines versatility and efficiency in system control applications. With its robust architecture, this device seamlessly integrates into various settings, delivering unparalleled performance for diverse monitoring and control tasks.
Key Features
- Digital I/O: Equipped with 40 digital I/O bits organized into five banks (8 bits each), each bank can be programmed flexibly as input or output, making it perfect for controlling processes and monitoring the status of switches and contacts. Scanning capabilities allow for the writing of unique output patterns and reading input banks at speeds of up to 1000 readings per second.
- Pattern Matching: Advanced features like pattern matching enable the execution of complex event algorithms, increasing overall efficiency in system management.
- Voltage and Current Management: Supports external voltage levels of up to 30V and provides an output current sink of 300mA, facilitating the control of external devices such as RF-microwave relays.
Analog Outputs
The Keithley 3750 features two analog outputs, ideal for general-purpose applications such as setpoint control or bias supplies for devices under test. These outputs are programmable as either voltage (±12V) or current (0-20mA or 4-20mA), ensuring flexibility in various testing conditions.
Enhanced safety measures include compliance monitoring for current and voltage, along with an automatic disconnection feature during fault conditions. Each channel is equipped with output relays for mechanical isolation, safeguarding your sensitive equipment.
Counters
With four 32-bit counters capable of handling a maximum input rate of 1MHz, the Keithley 3750 provides precise control for event counting and totalizing across a variety of system components, including fixtures, limit switches, and time-related measurements. Like the digital I/O, these counters are usable in scanning operations, with reading rates reaching up to 1000 readings per second.
Self-Calibration
When integrated with a high-performance multimeter option, the Model 3706 mainframe allows for self-calibration of analog outputs and counter thresholds, ensuring ongoing accuracy and reliability.
