Controllers And Alarms

The 8864 controller provides simultaneous display and alarm functions for up to 64 input variables. 16, 32, 48, and 64 channel display modes, and I/O modules arranged in groups of 16 channels, allow economical configuration of systems. This easy-to-configure, user friendly controller is ideal for centralizing display and alarm functions in critical multipoint monitoring applications. The similarity in function and user interface between the 8864 and the 16 channel 8800 makes usage of this family of controllers straightforward where both are used. Features 16, 32, 48, & 64 channel display modes accept inputs from many sensor types and signal ranges. Input types include 4-20mA, Modbus, and wireless options. Ethernet with Modbus TCP serves/client and web server for configuration and monitoring RS-485 serial ports allow simultaneous Modbus Master/ Slave operation. Two standard ports and two optional isolated ports Three independent alarm levels per channel. “Relay Acknowledge” feature allows silencing of external audible devices during alarm conditions QVGA Color LCD displays monitored data as trends, bar graphs and engineering units. Readouts change colors to indicate alarms CSA certified for Division 2 potentially hazardous areas Five standard SPDT 5-amp alarm relays. HORN, FAULT and three programmable alarm relays Options cards such as 4-20mA inputs, 4-20mA outputs, discrete and programmable alarm relays and bridge sensor inputs Cal Mode offers push-button zero/span calibration for remote sensor applications Authorization Mode allows locking of critical settings Data Logger onto SD card allows recording of minimum, maximum, and average values for one year Power supply options include both 150 and 600 Watt Magnetic keypad standard for non-intrusive operation in potentially hazardous locations Enclosures include wall mount NEMA 4X - Non- Metallic, 316 SS, XP and Rack/Panel Mount 8864 Controller Input 12 bit 4-20mA into 150 ohms input impedance; includes +power supply terminals for each channel for routing power to two or three wire transmitters Serial Ports Modbus Master and Slave RS485 ports equipped with Tx / Rx LEDs Ethernet Port Modbus TCP Master/Slave port with web server (Gateway for Ethernet IP, Bacnet, and other protocols available) Alarm Relays 5 amp 30VDC or 250VAC resistive Form C Analog Outputs (Optional) 16 bit 4-20mA output.

Channel configurations include 16, active channels. Cells indicate alarm status by color. BAR GRAPH SCREEN Displays 16 channels at a time. Bar graphs change colors to indicate alarm status. 24 HOUR TREND SCREEN Displays 1 channel at a time as most recent 24 hour trend. Top data fields include current reading, max – min – average readings over the 24 hours, range, channel ID and engineering units. COMBINATION SCREEN Displays 1 channel at a time as most recent 30-minute trend, bar graph and large engineering units. Top data fields include current reading, max - min -average readings for trouble shooting, range, channel ID, and engineering units. Readings change color and flash on alarms. Flashing color becomes steady after acknowledge. ZONE SCREEN Displays all eight possible active zones. Alarm cells change colors and name field flashes indicating alarms. Allows user direct access to screen that shows which channels belong to each zone.   Product Data Sheet
