Product Description:
The KS40-102-00090-049 is a panel-mount temperature controller manufactured by Danaher for the Thermal Controllers series. In an automated line, it accepts standard process signals, converts them into a controlled output, and holds heaters or chillers at a selected set point. The unit combines input conditioning, PID calculation, and status indication in a single 1/16-DIN housing, making it suitable for ovens, environmental chambers, and plastic processing machines that require precise thermal regulation. By integrating directly with sensors and actuators, it eliminates external converters and simplifies cabinet wiring. Its faceplate follows international sizing standards, so existing panels can accommodate the controller without extensive modifications.
Protection on the operator side reaches IP65, preventing dust and water spray from entering through the keypad, while the rear enclosure is rated IP20 for installation inside a closed cabinet. The upper readout uses 10.5 mm-high LEDs that remain legible at typical viewing distances in production areas. Analog current inputs pass through a 49 Ω shunt, translating 0–20 mA transmitter signals into a proportional voltage for the controller’s analog-to-digital converter. Voltage-mode sensors connect across a 110 kΩ input resistor that minimizes loading and preserves signal accuracy over long cable runs. These input options allow the controller to receive signals from commonly used industrial temperature and process sensors.
The secondary status line uses 7.8 mm-high characters, allowing operators to view the set point or alarm codes without crowding the main display. The controller resists shocks of up to 15 g with a pulse duration of 11 ms, protecting its internal boards from impacts caused by cabinet door movement or transportation. Continuous operation is permitted at an annual average of 75% relative humidity in condensation-free environments, including applicable food-processing and textile facilities. Field wiring connects to rear terminals with an IP00 rating. Because live parts at these terminals remain accessible, the controller must be installed behind a closed panel to provide protection against accidental contact.
