The 369-HI-R-M-F-0-H-E offers a number of options. This includes 12 RTD inputs. The RTD units are located on the rear of the unit on the left-hand side. This unit also has an optional metering package. The metering package adds access to VT inputs that will allow for voltage and power elements. Metering of Hz, kVA, KW, volts, and MWhrs is possible with this option.
The 369-LO-0-M-F-E-0 also has an additional fiber optic port installed. The fiber optic port has a baud rate of 1200 to 19200 and uses Modbus RTU protocol. This is used for channel 3. When used for channel three, the channel 3 RS485 connection is then disabled. However, the unit will still have other RS485 ports available. Additionally, the unit has an RS232 port that can be used to connect a PC. This is typically used to communicate with GE’s EnerVista software.
