Schneider RE17RCMU Harmony Modular Timing Relay 8A 1CO off-delay 24V-240V

The Schneider Electric RE17RCMU is a Harmony modular off-delay timing relay with an 8 A rated output and a single changeover (1 C/O) contact, accepting a wide supply of 24-240 V AC (50/60 Hz) or 24 V DC. Seven selectable time delay ranges from 0.1 seconds to 100 hours make it well suited to diverse industrial and commercial timing applications.

Features and benefits:

• Universal 24-240 V AC / 24 V DC supply range eliminates the need for multiple relay variants across different site voltages
• Seven selectable time delay ranges from 0.1 s to 100 h cover both short-cycle and long-duration applications
• LED status indicator provides continuous visual feedback on relay state and active timing function
• Cadmium-free contacts and self-extinguishing housing support environmental compliance requirements
• Compact 17.5 mm width saves valuable panel space on 35 mm DIN rail installations

Applications:

• Motor control panels requiring delayed de-energisation after a stop command
• Industrial automation sequences with timed off-delay control logic
• HVAC and ventilation systems for fan run-on control after shutdown
• Building automation panels with time-delayed relay switching outputs
