The SIEGER 5704 is a 4-channel gas control card for the Sieger System 57 intelligent gas detection system.Product details are as follows:
Features
Input Compatibility:Each card offers two input options:one for mV and one for 4-20mA sensors or transmitters.
Display:Provides display and alarm functionality for all Sieger gas detectors.A simple,backlit,multi-section LCD displays gas readings and status in both analog bar graph and numeric form,along with an alphanumeric message area for sensor status(as well as engineering functions).
Alarm:Multiple alarm modes are available,including single,zoned,preferred,primary,time-delayed,upgrade options,and increased alarm ratio.Sensor performance monitoring is also available.
Technical Specifications
Output:Provides two fault-monitored switched DC outputs and at least six passive outputs.
Additional Information
Mounting:A rack-mounted enclosure provides flexible mounting for the fire and gas control cards.Relationship with other cards:Fire alarm cards and gas cards can be freely mixed in the same rack.The 5704F four-channel control card provides control functions for up to four fire detection circuits,while the 5701 gas control card is used for single-channel operation.
