Optional Features
In addition
to its standard features, the 7HL has 3 important optional features:
- Digital communications featuring an opto-isolated EIA
RS-485 communications port with Modbus® or JBUS protocol (this option is
not available with the retransmission output). A closed logic input enables
remote operation from the serial link; an open logic input enables local
operation from the front panel.
|
- An auxiliary power supply for powering external
transducers. Jumper selected isolated outputs at 5, 10, 12 or 24 Vdc (25 mA
max.) are available.
- A linear analog retransmission output of the process
variable is available as an isolated, 0 to 20 mA, 4 to 20 mA or 0 to 10 Vdc
signal. This output is programmable and can have a digital filter applied to
the retransmission.
