• Applications requiring reliable on/off switching with visual feedback
• Retrofits and equipment upgrades where simple relay replacement is planned

Key specifications

• Type: Electromechanical relay for control and switching applications
• Visual indicator: Multicolour status indication for operating state visibility
• Weight: 122 g, suitable for compact installations
• Mounting: Designed for panel or enclosure installation (standard mounting form factor)
• Function: Intended for reliable switching and signal indication in control circuits

How to use

Mount the relay in the appropriate DIN rail or panel location compatible with its form factor, ensuring secure mechanical fixation and correct orientation. Connect the coil and contact terminals according to the control circuit schematic, observing proper polarity and rated control voltages for the system. Use the multicolour indicator to verify status during initial commissioning and routine checks. Follow standard electrical safety procedures: isolate power before wiring, use appropriate wire sizes, and tighten terminal connections to the manufacturer’s recommended torque.

Usage recommendations

Use the relay in environments within the specified temperature and humidity ranges of typical control panels, protect it from excessive dust or moisture, and avoid exposure to corrosive atmospheres. For reliable performance, incorporate appropriate surge suppression and ensure contact loads remain within the switch ratings of the relay.
