MTL4016

The MTL4016 is a two-channel, dual relay output switch and proximity detector interface unit built for intrinsically safe operation in hazardous area process control applications. Designed to bridge sensors located in explosive atmospheres with safe-area control systems, this module allows two proximity detectors or switches in a hazardous area to each control two independent safe-area loads — making it particularly well-suited for applications where a single sensor’s status must feed two separate systems, such as a control loop and a shutdown system simultaneously.MTL4016

This unit is part of the respected MTL 4000 Series isolator range from Eaton’s Crouse-Hinds division, a product line with decades of proven performance in the oil and gas, petrochemical, and process industries. The module includes line fault detection for broken or shorted lines, earth fault detection facilities, and phase-reversal switches on each channel so that alarm signals can be configured for either state of the connected sensor. Power and switch status are clearly indicated via onboard LEDs, supporting fast visual diagnostics in the field.MTL4016

This listing offers a used and fully tested MTL4016, inspected to confirm proper operation before shipment. Purchasing a professionally tested surplus unit is a cost-effective way to source a reliable replacement or spare without long lead times. The module’s reed relay outputs, 250V AC isolation between safe and hazardous area circuits, and SIL 2 capable rating per IEC 61508 make it a dependable choice for safety-critical installations.MTL4016

Compatible with NAMUR and DIN 19234 standard proximity detectors, the interface mounts on standard DIN rail and connects via screw terminals. Whether used as a direct replacement in an existing process safety system or integrated into a new panel build, this tested unit delivers the performance and certification credentials expected from industrial-grade intrinsic safety equipment.MTL4016
