INTRODUCTION
1.1 General
The Sentry 5000-32-
IT Controller (“Controller”) is the primary component of a gas detection system. The
Controller design combines a framework of essential components with an assortment of configurable
hardware modules selected during the system design phase to meet the specific application
requirements.
1.2
Controller Framework (Platform)
The following components provide the platform for Controller configurations:
•
Enclosure
•
Power Supply
•
Single Board Computer (SBC)
•
Touch Panel Computer (TPC) Graphical Interface
•
DIN rails for mounting three Configurable Hardware Modules
1.3
Configurable Hardware Modules (Stacks)
The following components are selected based on application requirements to complete individual
Controller designs.
•
Modbus Stack
The Modbus Stack is comprised of a bottom board containing eight programmable relay outputs
and a top board providing wiring points for two Modbus RTU RS-485 channels for sensor module
connection. Maximum of sixteen modules per loop.
•
Analog Input Stack
The Analog Input Stack is comprised of a bottom board containing eight programmable relay
outputs and a top board providing wiring points for sixteen 4-20mA inputs for sensor module
connection.
•
PSG Stack
The PSG Stack is the classic Sentry communication bus. It is comprised of a bottom board
containing eight programmable relay outputs and a top board providing wiring points for 2 loops
of eight PSG multiplex channels for sensor module connection. PSG is a proprietary SMC sensor
module protocol.
•
Digital Input Stack
The Digital Input Stack is comprised of a bottom board containing eight programmable relay
outputs and a top board providing wiring points for eight dry contact inputs.
•
Analog Output Stack
The Analog Output Stack is comprised of a bottom board containing eight programmable relay
outputs and a top board providing wiring points for sixteen 4-20 mA output connections.
•
Digital Output Stack
The Digital Output Stack is comprised of a bottom board containing eight programmable relay
outputs and a top board providing wiring points for an additional eight high capacity Form C
Relays.
