Analog Voltage Expansion
This is an eight-channel analog DC voltage input
panel used to integrate exhaust gas analyzers,
multi-channel Lambda sensors, O2 sensors,
pressure transducers, and other voltage output
devices. The standard configuration is seven 0–10
VDC channels (45 to 51) and one 0–20 VDC channel (52). Other configurations are available upon request
including 0–1 V, 0–5 V, and 0–30 V in any combination.
Excitation and reference voltages are available if needed. The +12F excitation voltage is limited to 500 mA
output. All others are limited to 100 mA.

Receptacles are color coded. All are keyed the
same and use the same pin out. The channels are
configured in the software as to the type of sensor
used. Prefabricated cables are available to connect
to this panel:
• 1200A-2462-x: Un-terminated cable for input
only, x=color
• 1200A-2462-01-x: BNC terminated cable for
input only, x=color
• 1200A-2860 w/1200A-2188: Battery voltage
input cable for 20 V channel only
• 1200A-2469-x: For pressure transducers or
other devices requiring a +5.00VDC excitation
voltage, x=color
The input circuitry can be damaged if more voltage
is applied by the sensor than what the channel is
designed for.
!
CAUTION
Use of custom sensors requires special
modification to the system configuration file.
