The 440R-G23216 is suitable for monitoring a variety of safety devices in industrial applications :
Guard Interlocks: Monitoring 1 N.C. or 2 N.C. contacts on hinged or sliding guards.
Emergency Stop (E-Stop): Monitoring single or dual-channel E-stop pushbuttons.
Light Curtains (OSSD): Direct connection to 2 PNP OSSD outputs from safety light curtains.
Safety Mats: Monitoring 4-wire safety mats .
Process Machinery: Manufacturing, material handling, packaging, and robotics.
Installation: Installation must be performed by authorized and trained personnel only . The device is designed for DIN rail mounting in a control cabinet.
Risk Assessment: Before installation, a risk assessment of the machine must be performed to determine if the relay's specifications are suitable .
Output Fusing: External fusing is required for the safety output contacts: 6 A slow blow or 10 A quick blow is recommended .
Contact Ratings: Safety and auxiliary relay contacts are rated for AC-15 (6 A/250V AC inductive) and DC-13 (3 A/24V DC) . The solid-state PNP auxiliary outputs are short-circuit protected .
Do Not Repair: If any malfunction or damage is present, do not attempt to repair. The unit must be replaced .
Removable Terminals: The screw terminals can be removed to simplify wiring and replacement .
A: It is a single-function safety relay used to monitor safety devices (like E-stops and light curtains) and safely switch off machine power in response to a fault .
A: It is rated up to PLe, Category 4 (per ISO 13849-1) and SIL CL3 (per IEC 62061/61508) .
