Full featured weighing indicators have
OIML and CE approval: Variohm offers
new comprehensively equipped weighing
indicator models
Suiting both scale and process weighing
tasks, the new 20i & 22i series can be
configured with a choice of 6-digit LCD or
LED displays. And, with an auto-switching
AC supply or optional battery power
for mobile equipment use, maximum
durability is ensured with an IP67 rated
stainless steel housing and mounting
fixtures. A menu driven user interface
includes a membrane keypad with 12
numeric keys + 7 functional keys that
allow straightforward selection of built-in
weighing and counting modes where
an Alibi memory retains the last 100k
transactions.
As standard, the units offer selectable
digital I/O, four dry-relay outputs and two
opto-isolated inputs for setpoints and
batching. PC or PLC connectivity includes
an RS 485 full duplex interface or an
optional Ethernet TCP/IP and USB 2.0
board can be specified. Two serial ports

The indictors will drive up to 10 x 350 Ω
load cells (4 to 6 wires) or up to 20 units of
700 Ω.
The many application configuration
possibilities for the 20i and 22i include
