safety relay module ESRE-4A2B

Product catalog summary

Product Introduction
The ESRE-4A2B Series Safety Relay Expansion Module is designed to meet the PLe safety level of ISO 13849-1. It is suitable for expanding output contacts of safety relay expansion modules in industrial sites with high safety requirements. The module expands safety switch signal input into 4 normally open (NO) safety output contacts and 2 normally closed (NC) auxiliary output contacts.

Product Features
- Designed according to ISO 13849-1 (Category 4, PLe).
- Relay output: 4 NO and 2 NC auxiliary contacts.
- Cross-diagnose monitoring function.
- Power supply reverse polarity protection.
- Visualized status indicator for easy diagnosis.
- Detectable terminal for easy maintenance.
- Input power overvoltage protection.
- Standard 35mm width guide mounting design.

Application Details
The ESRE-4A2B module connects to the output terminal of the previous device. When the previous device sends the correct signal, the related contacts of the expansion module perform the corresponding action. It features an automatic reset and safety feedback loop.

Warnings
- Carefully read the manual before installation.
- Ensure the power supply is cut off when wiring.
- Clip the product directly onto a 35mm rail inside the equipment cabinet.
- Before disassembling, cut off the power supply and loosen the locking screws or remove terminals.
