CR-4000-CR4-R1234 CR-4000 with channel 1, 2, 3, 4 and alarm relays (low/high) by BW Technologies
For continuous monitoring and control of toxic gases, combustible gases and oxygen hazards, the CR-4000 is designed for installation and operational simplicity. The four channel gas detection controller records and displays peak (max) gas detected by each channel on demand. Auto fuses protect all circuits and reset automatically when the circuit power returns to normal. No fuse replacement required. User-friendly with a pre-programmed channel switch for gas type, sensor range and alarm level.
Features:
- Individual, continuous, alphanumeric "status" LCD for each channel
- Slim profile: depth only 2.5 in./6.35 cm
- Easy installation - simply hang on the wall, connect the power (AC or DC) and gas transmitters
- Local 85 dB audible alarm
- Field programmable alarm levels on each channel
- Simple operation
- Mix, match or change the gases monitored
- Three standard common, 10 amp SPDT relays. Low, High and Fault general alarms
- Up to eight additional discrete relays - two per channel for LOW and HIGH alarms. Each channel is programmable for energized/deenergized, latching/non-latching and audible ON/OFF
- Multi-functional external RESET can be used to reset or cancel all latched alarms; displays peak (maximum) gas detected on each channel and tests all audible/visual alarms
- Accepts 4-20 mA signal input from any 4-20 mA gas transmitter
Accessories and Options:
Install up to eight relays. Two factory installed 10 amp SPDT relays per channel. The Low Alarm/High Alarm independent discrete relays are user adjustable for power and assignment, including normally energized/de-energized, latching/non-latching, zoning (Park) and audible alarm activation.Part Number: CR4000CR4R1234
