TempScan Scanning Cards
The TempScan/1100 master unit and any Exp/10A and Exp/11A expansion units connected to this master
unit, can each accept the following three kinds of optional solid-state scanning cards:
• TempTC/32B Thermocouple Scanning Card which measures thermocouples
• TempV/32B Voltage Scanning Card which measures voltages
• TempRTD/16B RTD Scanning Card which measures RTDs (resistance temperature devices)
Note: Do not mix TempScan/1100 and MultiScan/1200 scanning cards within the same system.
TempScan/1100 scanning cards are designed for and supported only by the TempScan/1100
master unit. Likewise, MultiScan/1200 scanning cards are designed for and supported only by
the MultiScan/1200 master unit. Otherwise, operating errors or equipment damage may
occur.
Each scanning card contains screw-terminal blocks for quick and easy input connections. Connections are
made by inserting the wire into a screw-terminal socket.
Several tie-down holes are provided for tie-wrap strain reliefs to keep wires from all the channels organized
and manageable before they exit the rear panel of the master or expansion unit.
To keep noise outside and to maintain a constant internal temperature, each scanning card fits into a
shielded metal enclosure inside the master or expansion unit. The foam padding on the scanning card
provides an air dam to minimize gradients.
