Product Description

The SITOP PSE200U selectivity module provides four-channel electronic circuit protection for 24 V DC loads, with per-channel trip thresholds adjustable from 0.5 to 3 A. When one branch experiences an overload or short circuit, only that channel disconnects—the healthy branches continue operating at full voltage. NEC Class 2 certification makes this module suitable for limited-power circuit applications across North America.

Fault Signaling

A single change-over contact (SPDT) provides common fault signaling for all four channels, simplifying integration with a digital input module or an external indicator lamp. For local troubleshooting, each channel has its own multi-color LED on the front panel.

Installation

DIN rail mounting on a standard 35 mm EN 60715 profile. Screw terminals accept the load wiring directly. The module tolerates brief inrush peaks—such as those drawn by contactor coils or capacitive loads—without nuisance tripping.
