This board consists of a temperature sensing sub-module, with 6 thermistor inputs (10K thermistor), up to 6 thermocouple inputs (type K, J, T, N, S, E, B, or R), up to 6 IR (touchless) sensors, and a control sub-module, capable of driving TEC’s, resistive heaters, and PWM controlled ovens. There are up to 3 control channels, each capable of driving devices up to 400W (17A, 24V). Three fan control channels are provided; both speed-controlled fans and simple DC power-controlled fans can be used. Speed-controlled fans can be configured for PID controlled cooling of resistive heaters if desired.
Control algorithms include both classical PID control for analog controllable devices such as TEC’s and resistive heaters as well as thermostatic (On/Off) control for ovens that have only an “on” and an “off” state. Any of the control channels can be configured to automatically run at power-up.
Extensive safety features are included. Any temperature sensor can be used for monitoring and alerting if temperature exceeds defined bounds; optionally, power to heating devices can be cut if defined safe conditions are exceeded.
The system is designed for ease of scripted control and comes with script examples and with a dedicated Windows utility application to configure and run the system. Please see application screenshots at the end of this document for an application overview.
