MTL SD series Surge Protection Device

The MTL SD series surge protection devices are designed to provide reliable protection for process equipment, I/O systems, and communication networks. Here is a detailed introduction:

Features of MTL SD series surge protection devices

High-Density Design: The SD series features an ultra - slim design for individual modules, resulting in a high packing density. This allows the modules to "double - up" as feedback terminals, saving space.

Versatile Applications: It is suitable for a wide range of applications, including thermocouples, 4 - 20 mA instrument loops, shutdown systems, and fire and gas detectors.

Reliable Circuitry: The SD series uses proven reliable hybrid circuitry to ensure stable and effective surge protection.

Easy Installation: With a standard DIN - rail mounting method, the installation is simple and convenient.

Optional Loop Disconnect: It provides an optional "loop disconnect" feature, which offers fused protection against fault currents. This feature allows for easy isolation of field circuitry from protected circuitry without the need for additional disconnect terminals.

High Surge Current Capacity: It can handle a maximum surge current of 20 kA, providing strong protection against surges.

Intrinsically Safe: The SD series is ATEX and IECEx certified, which means it is intrinsically safe and suitable for use in hazardous areas.

Models of MTL SD series surge protection devices

MTL SDX Models: Available in 7V, 16V, 32V, and 55V versions, namely SD07X, SD16X, SD32X, and SD55X. They are suitable for various applications such as thermocouples, 4-20 mA loops, shutdown systems, and fire and gas detectors.

MTL SD Models: On the basis of the SDX series, the SD models add a fuse / disconnect package to provide protection against fault currents. Common models include SD07, SD16, and SD32.

MTL SDR Models: These are designed for high - speed data links with a high bandwidth. They are available in multiple voltage variants and can protect communication systems such as RS232, RS422, RS485, and bus - powered systems. Typical models are SD07R,  SD07R3, SD16R, SD32R, and SD55R.

SD32T3, SDRTD Models: The SD32T3 is for separately powered 4-20 mA loops, and the SDRTD is for protecting three-wire RTD loops. They provide full three - wire protection in a compact unit.
