This Allen Bradley temperature monitoring relay from Rockwell Automation is an electrically controlled switch that turns the power on or off in a circuit. Its two contacts operate simultaneously to prevent overtemperature, opening or closing when the temperature is within or beyond the preset threshold.The first contact supplies power to a circuit or device, while the second activates an alarm to alert you if the temperature exceeds the desired limit. Compact dimensions of 98.8 (L) x 22.5 (W) x 89mm (H) for use in tight spaces. Broad operating temperature range of -25°C to +60°C for use in a variety of hot and cold environments. Wide supply voltage range of 24 to 240V AC/DC makes it suitable for most power applications. Trimmer potentiometers provide a simple way to set overtemperature thresholds. Number of contacts as change-over contact. Number of contacts as normally closed contact.
