1600A-N1P
1.0 Introduction
The Detcon Models 1600A-N1P is a “user-configurable” multi-channel alarm controller. The 1600A is
configurable for up to 16 channels. Through the use of I/O modules the 1600A can receive analog inputs
consisting of 4-20mA, and can alternatively poll serial sensors via RS-485 Modbus™ RTU.
The 1600A-N1P controller uses a modular design approach that allows the user to customize the selection of
stand-alone input and output modules. I/O modules are available in four channel sets for 4-20mA inputs, relay
outputs, and 4-20mA outputs. Detcon’s I/O Modules are DIN rail mounted and stackable allowing for
seamless system expansion. These addressable I/O modules can be located remotely near the gas sensors to
simplify wiring.
The status of sensor inputs is displayed on a backlit graphic display that utilizes a touch-screen user interface.
Typical sensor status includes channel number, tag name, gas type, concentration, and alarm/fault status. Each
input channel can be assigned up to three alarm levels and fault. A standard RS-485 or optional RS 232 serial
output is provided for communication with PLC’s, PC’s, and monitoring devices.
The controller can be powered by 110/220VAC, 20-30VDC, or both. The enclosure is rated for NEMA 1
locations. Remote mounted gas sensors (purchased separately) can include serial or 4-20mA input devices
such as: toxic gas, combustible gas, or oxygen deficiency sensors. Additional features include: one-touch
Alarm Inhibit, Alarm Reset, and Alarm Silence (Acknowledge) functions. An Alarm Reset Switch can be
remotely mounted and wired to the 1600A controller. The 1600A controller provides for a unique
combination of user programming flexibility and customizable expansion capability, in a low-cost and simple-
to-operate package.
