ZIPLINK ZL-RS4-120 4-CHANNEL RELAY SOCKET ZLRS4120

Description:

The AutomationDirect ZIPLink ZL-RS4-120 is a 4-channel relay socket module used in industrial automation systems to interface PLC outputs with higher-power field devices. Commonly installed in control panels and machine automation systems, it allows low-power PLC signals to safely switch higher voltage/current loads. Maintenance teams, electricians, and system integrators use this module for installation, retrofit, or replacement to provide electrical isolation and reliable switching.

Applications:

The ZIPLink ZL-RS4-120 is widely used in industrial environments such as manufacturing lines, conveyor systems, and process control panels where PLC outputs must control devices like relays, solenoids, motors, or alarms. It provides isolation between control logic and load circuits while enabling multiple outputs in a compact DIN-rail module.
