The OMB-DBK207
and OMB-DBK207/CJC signal
conditioning and expansion boards
can be configured, on a per-channel
basis, with up to 16 isolated OM5
(5B) analog input modules. Both
boards feature screw terminals per

channel for the convenient
connection of field signals as well
as sockets for current conversion
resistors (supplied with OM5 (5B)
current I/O modules, sold
separately). The OMB-DBK207/CJC
also includes per-channel cold­junction compensation. This allows
OM5 (5B) thermocouple modules to
output linearized and compensated
values eliminating the need for any
components apart from a user­supplied thermocouple.

Each user-configurable OM5 (5B)
signal conditioning module offers
500 V isolation from the system and
from other channels. A wide variety
of analog input modules are
available for measuring temperature
(thermocouple and RTD), strain,
volts, current, and frequency.

Up to 16 OMB-DBK207 and/or
OMB-DBK207/CJC boards can
be daisy-chained (via multiple
OMB-CA-37-x cables) providing
expansion for up to 256 analog
input channels. For applications
with both analog and digital I/O
channel expansion requirements,
the OMB-DBK208 and OMB­DBK210 expansion boards are
available. All OMB-DBK signal
conditioning and expansion boards
are scanned at 5 µs/channel.

The OMB-DBK207
and OMB-DBK207/CJC ship
with panel-mount hardware but
they can also be rack-mounted
with the optional rack mounting kit.
The OMB-DBK209 and OMB­DBK206 adapter boards are used to
convert the 100-pin (P4) connector
from the OMB-DAQBOARD-2000
series boards to three expansion
ports P1, P2, and P3).
