TMO2D

Display and control module
Applications
A display/controller for use with:• XMO2 thermoparamagnetic oxygen transmitter• OXY.IQ galvanic fuel cell oxygen transmitter• XMTC thermal-conductivity hydrogen/gas transmitter• Any other 4 to 20 mA output transmitter

Features• Two-line x 24-character backlit LCD• Single or dual isolated, 4 to 20 mA outputs• Up to four ﬁeld-conﬁgurable process alarms• Automatic calibration relays

Display and control module

The TMO2D is an optional display and control module thatenhances the performance and operation of transmitterssuch as the XMO2, XMTC or OXY.IQ. It provides a two-line
x 24-character backlit LCD display, display and option
programming via keyboard, recorder outputs, alarm relays,
and relays for driving sample system solenoids for automaticzero and span calibration, as well as a 24 VDC power supply
for the transmitter.

Autoveriﬁcation/autocalibration

The TMO2D provides long-term, hands-off operation withthis optional feature. When initiated, the TMO2D controls
solenoid valves in the sample system to bring zero and spangases to the transmitter. Then TMO2D software compares thecalibration gas readings with factory data to verify proper
calibration. If an adjustment is necessary, the TMO2D makes
corrections automatically and notiﬁes the user via the front
panel display and alarm contacts.
