MULTI-POINT CONTROLLERS > HIGH DENSITY
C1 Multi-Point Alarm Controller Nema 4X with 16 bridgestyle catalytic bead input channels, SPDT common alarm relay board, 100dB audible alarm, with local alarm reset button.
Includes Modbus RTU slave RS-485 port for sending data to PC, PLC or DCS.
The C1 Protector Graphic Display / Alarm Controller provides display and alarm functions for up to 16 input variables.

A graphic LCD displays data as trends, bargraphs and engineering units. Three adjustable alarm levels are provided per channel. Relay outputs with programmable voting logic allow control of beacons, horns and other
alarm events. The horn relay may be set for steady or pulsing operation.
4-Standard 5A SPDT common relays for HORN, HIGH, WARN & FAULT. Options such as discrete channel alarm relays, 4-20mA input / output and direct sensor input conditioning are readily incorporated into the standard unit by connecting appropriate boards via an internal expansion bus, allowing versatile system configuration and rapid built-to-order capability.
Alternatively, a standard RS-485 MODBUS® master port allows
input data to be retrieved from remote MODBUS slave devices, including
GASMAX monitors or C2 controllers. An RS-485 MODBUS slave port allows up to 128 C1s to be multi-dropped onto a single data highway for interrogation by a MODBUS master device.
Measurement ranges in engineering units, adjustable alarm set-points, dual serial interfaces and many other features allow the C1 controller to satisfy the needs of many demanding applications.
Nonvolatile memory retains all configuration
data indefinitely.
Analog inputs are acepted and configured for every sensor, showed and displayed individually.
