Digital Analog Power Junction

Four independent delay channels or Two fully-defined pulse channels s. Front-panel BNC outputs deliver TTL, ECL, NIM or variable level (-3 to +4 V) pulses into 50 Ω or high impedance loads.
Triggering - The DG535 can be triggered internally from 1 mHz to 1 MHz with four-digit frequency resolution. External, single-shot and burst mode triggers are also supported.

DG535 - Digital Delay Pulse Generator - SRS

Other Specs Include

• 5 ps delay resolution
• <100 ps rms jitter
• Adjustable amplitude and offset
• Delays up to 1000 seconds

The delay and pulsewidth for each channel are independent with 2-20 volt output range, allowing the user to drive a wide range of load circuitry. This pulse generator offers several operating modes, including continuous, burst, single shot and external trigger/gate, allowing complete control of the pulse outputs. - https://www.quantumcomposers.com/

Thermocouple, RTD, Temperature monitoring is central to the majority of data acquisition systems, be it to save energy costs, increase safety, reduce testing time…whatever your reasons, you will need a device to measure the temperature - a temperature sensor.

How to Use Your PC to Measure Temperature

Thermocouples, resistance temperature devices (RTDs), thermistors and infrared thermometers are all types of temperature sensor. Which you choose depends on factors like your expected maximum and minimum temperatures, the accuracy you need and your environmental conditions.

752-RTD: RTD Resistance Temperature Measurement, Digital I/O, Counting, Analog Output

• Measure temperature using RTDs or Pt100 sensors, and voltage signals
• With extra hardware monitor thermocouples and strain gauge bridges
• Includes the powerful yet easy-to-use Windmill software for Windows: no programming required
• Connect up to 8 USB units to one PC

Here is a way you can learn, How To Interface PC to the Outside World.

Temperature Control with a PC

Based on the above the Octagon computes a sensible heating/cooling current value and transmits a corresponding analogue signal to the current control electronics in the TC-box.
The current control electronics control the current provided by a big external power supply flowing through the peltier heating elements according to the signal received from the Octagon.

This is a project that will help students learn both hardware and software aspects of a control system. Here you can test out an automation program on a PC with minimum external hardware.

When you implement in the field, the system has to be a dedicated real time uC based product on custom firmware. Systems with OS + Software combination are not known to be reliable in Process Control. But OS + Software is good for Supervisory Systems which get their data from Real Time Controllers.

So a front end controller must be Rugged, Non-PC based and Non-OS based embedded system. With a Robust and Compact (means fast) firmware.

The firmware should be Polling or Interrupt based but with both internal and external watchdog. Most important a Power supply Management that resets system properly over Brown-outs and Black-outs. Even today some Embedded Systems i have to turn off and on after power resumes.

Don't Forget, Multiple Watch Dogs and Multiple Power Management for graceful start of system !! Use one big SuperCap if you want. Else people will go back to Thermostats.

Industrial Automation enables Higher skill levels for workers and reduces danger of accidents too. Now the emphasis is for Energy Efficient Industrial Production, not only to save Energy Costs but as a Social Responsibility.

Industries should not pollute water bodies and the atmosphere, this brings us to new process control area of Air and Water Quality Measurement and regulation.
