LS DI 24 VDC isolated CHARM specifications

Installation notes

When a CHARM Terminal Block is used, the input channel can be used as a conventional isolated input channel.
When a CHARM 3-Wire DI Fused Injected Power Terminal Block is used, the input channel can be used as a dry contact input channel.
The CHARM 3-Wire DI Fused Injected Power Terminal Block can be used to provide an additional connection point for 2 and 3-wire devices connected to this CHARM.
