BRM-4S belongs to industrial relay module family, DIN rail mounting design, protection class IP20. Power supply DC24V. Each channel has independent optocoupler isolation and relay contact. Contact rating normally up to 250VAC 5A / 30VDC 5A.

LED status indicators for each channel show relay ON/OFF state for fast on-site troubleshooting. Screw terminal block for easy wiring. It isolates PLC control side and field load side to protect PLC output points from surge and inductive load damage. Operating temperature range 0~60℃.

BRM-4S is widely used standard relay spare part. When the original module fails, replacement with identical BRM-4S can reuse DIN rail installation, control wiring and load cables. Technicians install the module, check channel action and contact output, so PLC signal switching system resumes operation and reduces downtime.

Before shipment, every BRM-4S undergoes comprehensive functional inspection including power-on self-test, each channel pull-in test, contact continuity check and isolation resistance test. All products come with 12-month warranty. Our automation technical team provides remote support for installation, wiring guidance and fault diagnosis. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, BRM-4S is reliable spare multi-channel relay module for PLC control systems. It restores isolated signal switching for field actuators, extends service life of automation assets and avoids whole control system renovation.
