Product details
The MASSO Relay 8 – Opto 4 DIN Module connects your MASSO controller’s TTL outputs to relay switching and opto-isolated control outputs. With 8 independent relay channels and 4 opto-coupled outputs, it provides a practical interface for controlling CNC equipment such as coolant systems, vacuum tables and spindle control circuits.
Powered by a 24V DC supply, the module supports PLC and VFD control signals, while electrical isolation separates the controller from connected equipment. Multi-colour relay indicators make troubleshooting easier by showing normal operation or a failure to switch.
