2.1 Hardware Configurations
The Model 1600A-N4X is a “user configurable” alarm controller platform. The basic 1600A-N4X Controller
includes the NEMA 4 panel enclosure with Controller Module (including display), Power Supply, two AC and
one DC breakers, and a DC over-voltage protection module.
NOTE: I/O modules are normally factory installed unless specifically instructed otherwise. A maximum
of 12 I/O modules will fit inside the standard N4X enclosure. I/O Modules are purchased separately.
The available Detcon I/O modules include:
Model DA-4 – Four channel analog 4-20mA input module
Model RL-4 – Four channel relay output module
Model AO-4 – Four channel analog 4-20mA output module
Detcon I/O modules are individually addressable and operate on 11.5-30 VDC. Each module communicates
with the controller via the RS-485 Modbus™ RTU protocol. A maximum of 12 I/O modules can be mounted
in the N4X enclosure. Other modules need to be mounted in separate enclosures.
