Allen-Bradley 1610-T0420S24 Dry Reed Relay

Allen-Bradley 1610-T0420S24 is a dry reed relay from Rockwell Automation's 1610 family, designed for compact, dependable signal switching in control panels and automation equipment. The suffix S24 indicates a 24 VDC coil, enabling straightforward interfacing with standard 24-volt logic and control circuits. The device uses hermetically sealed reed contacts, which provides fast operation and high isolation between the coil and the switched circuit, reducing cross-talk and false triggering in noisy environments. It is intended for use in applications where a small, low-power relay is required to switch signals or small loads without introducing significant leakage paths, and where reliable, repeatable contact closure is important. Because it employs a dry reed contact design, there are no electrolytic components in the contact path, contributing to longevity and stable performance in typical automation workloads. This model reflects Allen-Bradley’s long-standing approach to miniature relays that offer simple, robust operation within legacy and modern control architectures requiring clean electrical isolation between control circuitry and the load.
