TIMERS

Control relays function as switches that can open or close circuits electromechanically or electronically. They are typically activated by an electrical signal, causing them to change states and either allow current to pass through or interrupt the current flow. This operation enables control relays to manage and automate complex electrical processes and systems. Crouzet offers a comprehensive range of control relays for the Industrial Automation & Robotics industry, specializing in Time Delay Relays. Crouzet’s Timers are used to control the Start/Stop Function in Conveyor Systems, Assembly Lines, and Packaging Lines, and protect the System in High Speed Door applications.

MONITORING RELAYS

Monitoring relays are devices used in industrial automation to continuously monitor electrical parameters such as voltage, current, temperature, frequency, and phase sequence. They are crucial for ensuring the safe and reliable operation of machinery and electrical systems by detecting faults or deviations from normal operating conditions. These relays can trigger alarms, shut down equipment, or initiate other corrective actions to prevent damage or ensure system stability. In industrial and commercial installations, every device should be monitored by a Crouzet Monitoring Relay to optimize continuity of service. The control relay enables the operator to initiate maintenance operations or corrective actions to avoid expensive production shutdowns.
