Mitsubishi COC4-A01D1 Instruction Manual

The Mitsubishi COC4-A01D1 relay has a maximum switching capacity of 10A at 250VAC or 30VDC.
To install the relay on a DIN rail, align the mounting clip on the relay base with the rail and press down until it clicks into place. Ensure that the relay is securely fastened and the connections are tight.
Check the power supply to ensure voltage is within operational limits, inspect wiring and connections for any loose or broken parts, and verify that the relay coil is receiving the correct control signal.
Use a multimeter to check for continuity between the common and normally open contacts when the coil is energized. If continuity is present, the relay is functioning correctly.
Regularly inspect the relay for signs of wear or damage, clean it to prevent dust buildup, and ensure that all connections are secure. Replace the relay if any signs of malfunction are detected.
The operating temperature range for the Mitsubishi COC4-A01D1 relay is typically -40°C to +70°C.
The relay can be used in outdoor applications if it is housed in a weatherproof enclosure to protect it from moisture and extreme weather conditions.
The recommended coil voltage for the Mitsubishi COC4-A01D1 relay is 24VDC.
Replace the relay if it fails to energize or switch contacts, if there is visible physical damage, or if there is a significant increase in operating temperature.
The relay can be used in high-vibration environments if it is securely mounted and additional vibration-damping measures are implemented to prevent damage.
