MTL1991 Power Feed and Alarm Module

MTL1000 power bus module The MTL1991 provides the power supply feed to the power bus for the MTL1000 series isolators. A relay alarm contact and LED indicate power supply status. 2 modules may be used to provide a redundant power feed to the power bus when feeding power via terminal 5 with a maximum load of 1A. For single power feed use terminal 6, the maximum recommended load is 2A.

The MTL1000 range of modules and accessories is designed for use with process connected systems. It consists of compact isolating interface modules mounted on 35mm DIN rail. Power is provided through a DIN rail mounted power bus, to which, the isolator module is plugged into when clipped onto the DIN rail. Power is supplied to the isolators via a dedicated power feed module which also provides current limit protection in the event of a fault. The MTL1000 range modules provide power and status information via LEDs on the top of the module. Where module configuration is required, then switches are accessed by the user through the side cover.
