Phoenix Contact CBMC E4 24DC 1-4A S-R Current Monitoring Relay

The Phoenix Contact CBMC E4 24DC 1-4A S-R is a current monitoring relay that supervises load current in the 1 to 4 A range from a 24 V DC supply. In electrical control circuits, it translates observed current levels into a signaling output to indicate normal or abnormal current conditions and support interlocks or signaling in automation systems. Operating from 24 V DC, this device is designed to integrate with standard low‑voltage control wiring and PLC-or relay-based control schemes. The 1–4 A monitoring window defines the current that the relay watches, enabling simple supervision of load health without requiring external sensing components. As part of Phoenix Contact’s CBMC E4 family, the CBMC E4 24DC 1-4A S-R is geared toward compact installation in control panels where reliable current monitoring is needed to trigger protective or control actions. Typical applications include supervising motor, heater, or other inductive or resistive loads in automation projects, providing a clear signaling reference for downstream controllers when current levels move outside the expected range.
