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).
