The HTR module is a 3U, 12HP plug-in, in charge to to simulate 4 independent heater interfaces
Each HTR output circuit is redirected by a dedicated relay to a Nominal I/F or to a Redundant I/F: in this way each HTR Plug-In grants the capability to simulate four cold-redounded HTR circuits.
The HTR module can deliver a constant output or a programmable and periodic Pulse Width Modulation activation.
The plug-in module architecture follows the generic architecture compatible with the Power I/F Box
