Description
The Johnson Controls DX-9120-8454 is a Metasys DX-9100 Extended Digital Controller, Version 3 (TP78), supplied reconditioned. Version 3 replaces the N2 Bus of the Version 2 controller with the LonWorks (Echelon) N2E Bus, and this build uses TP78 twisted-pair transceivers.
Functionally it is the same extended digital plant controller as the rest of the family: on-board analogue and digital I/O with twelve multipurpose programmable function modules, schedule modules and optimal start/stop, running on 24 VAC ±10%, 50/60 Hz, and carrying an XT Bus for the XT-9100 extension module and XP-9102 to XP-9107 expansion modules. Johnson Controls applies the DX-9100 to multiple chiller or boiler plant control, air handling units, and distributed lighting and related electrical equipment.
