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.
