IFM Safety Relay G2001S 24V DC Type 4 Light Curtain Control Relay

Stop guessing why your safety line stops working. The IFM Safety Relay G2001S 24V DC Type 4 Light Curtain Control Relay is the missing link that keeps your light curtains reliable and your machine safe. If a sensor fails or a cable is wired wrong, production can halt and workers are put at risk. This relay watches the signals, blocks false trips and lets you keep the line moving without compromising safety.

IFM Safety Relay G2001S 24V DC Type 4 Light Curtain Control Relay

Machines that use safety light curtains often suffer from unwanted stops caused by sensor noise or wiring errors. Those stops waste time, raise maintenance costs and can lead to unsafe work conditions. The IFM relay solves this problem by providing mute control, clear status signals and built-in reverse polarity protection. It lets you decide when the curtain may be muted, shows you exactly why a stop happened and guarantees that the safety function stays within IEC 61496 Type 4 limits.

Benefits

• Reduces false stops, so your line runs longer without interruption.
• Shows clear LED status, making troubleshooting fast and easy.
• Protects against wiring mistakes with reverse polarity protection.
• Supports both manual and automatic mute modes for flexible operation.
• Meets strict safety standards, giving you confidence in compliance.

Usages

Use this relay in any machine that has safety light curtains or safety grids. It works well on packaging lines, robotic work cells, palletizers and conveyor systems where quick access to the guarded area is needed. The mute inputs let you pause the curtain while a tool is changed, and the safety outputs keep the machine stopped if the curtain is broken. It also fits well in assembly stations that require a clean, visible safety status for operators.
