4-channel 24 VDC electronic circuit breaker, 1–10 A/channel, RS-232 monitoring, LCD, time-delayed switching, IP20, DIN-rail.
Electronic circuit breaker module with 4 parametrizable channels for 24 VDC control and distribution systems. The device accepts 18 to 30 VDC input, provides four 24 VDC outputs, and allows each channel to be adjusted from 1 to 10 A. It includes time-delayed channel switching, adjustable trip behavior from 100 ms to 600 s, isolated signal contact, four active signal outputs, LCD status display, and RS-232 communication for current and voltage monitoring. The unit is DIN-35 rail mounted, IP20 protected, and intended for industrial low-voltage power distribution and load protection.

Use as a four-channel load feeder for PLC I/O, sensors, and actuators where each branch needs independent adjustable current limiting and tripping.
Prevents one faulty load from collapsing the entire 24 VDC control supply while preserving selective fault isolation.
Apply in machinery cabinets that require fault indication, remote reactivation, and serial diagnostics for maintenance personnel.
Provides visible fault states, isolated signaling, and RS-232-based monitoring to reduce troubleshooting time and manual intervention.
Deploy where multiple independent DC loads must be started with staggered timing and monitored for overloads, such as distributed actuators or valve islands.
Time-delayed channel switching and per-channel trip adjustment reduce inrush stress and help coordinate power-up sequencing.
