The C2 Protector Display & Alarm
Controller provides signal conditioning,
display and alarm functions for one or two
critical input variables.
Versatile
Designed to provide low-cost direct monitoring for one or two gas sensors or flame
detectors, the C2 Protector controller
offers a highly-integrated, complete solution for detection of hazardous conditions.
Versatile input signal conditioning options
allow direct connection of any GDS Corp
electrochemical sensor, and local or remote support for any GDS Corp combustible, PID or infrared sensor. Both channels
can be configured to accept analog inputs
from sources such as the GDS-49 Sensor
Transmitter, GDS-IR Point Infrared Gas
Detector or any standard 4-20mA source.
Additional C2 options include 5A SPDT
discrete relays, 4-20mA outputs, light
stacks and audible annunciators.
One popular application for the C2 is as a
dual gas detector equipped with one local
combustible sensor and one local toxic
sensor. Alternatively, two combustible locations may be monitored with one sensor
local and another remote.
Real-Time Display
A large graphic LCD screen displays input
data as calibrated engineering units, bargraphs or 30-minute trends. Three adjustable alarm levels per channel, combined
with programmable relays with voting
logic allows flexible control of beacons,
horns and other warning devices. Highly
visible red and yellow LEDs visually
indicate alarm status at all times.
Digitally Connected
An optional RS-485 MODBUS® slave
port allows multiple C2 controllers to
be multi-dropped on a single data highway. The C2 Protector controller is also
100% compatible with the ProtectorHMI
Visualization and Historian software that
can monitor, display and record data from
up to ten C1 Protector or C2 Protector
controllers.
Reliability
The C2 Protector controller is CSA certified to CSA C22.2 No. 152 for combustibles and Class I, Division 2, Groups A,
B, C, D for use in hazardous areas. An
optional NEMA 7 enclosure allows use in
Class I Div 1 areas. Up to twelve watts of
24 VDC power is available for auxiliary
devices or transmitters.
