Variant Description

Functionally the MTL4500 and MTL5500 range of modules are the same but differ in the following way:

– the MTL4500 modules are designed for backplane mounted applications- the MTL5500 modules are

designed for DIN rail mounting.

In both models the hazardous area field-wiring connections (terminals 1-2. and 4-5) are made through the

removable blue connectors on the top of the modules, but the safe area and power connections for the MTL454x

modules are made through the connector on the base, while the MTL554x uses the removable grey connectors

on the top and side of the module.

Note that the safe-area connection terminal numbers differ between the backplane and DIN-rail mounting models.
