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 system configuration.
This easy-to-configure, user-friendly controller is ideal for centralising 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/ Slaveoperation. Two standard ports and two optional isolated ports.
