The EMU305 cycles around the 16 thermocouple inputs, switching these inputs to the output.
The output is measured by the USC701 (CH1 set to measure T/C input,
with USBO input resistors).
The USC701 output is scaled 0-10Vdc equal to 0-1000°C.
This output is measured by the DPM135 digital indicator.
The SPL0510 decodes the Channel address number of the EMUs and displays
this number.
The operator can see both the channel number and the temperature
of that channel.
The cycle time between channels can be altered by the Step-Rate pot on the front of the EMU 1. The Auto-Manual switch on EMU 1 can be set to Manual and the channels advanced by the Step switch.
If any input channel exceeds the USC701 Alarm set value, then the RLY2 output is used to stop the cycling of the EMUs on this alarm channel. RLY1 can be used for separate temperature alarm. The operator can disable these alarms by pressing the Reset switch connected to the USC701.

Same application with 1 EMU305 and a different channel indicators.
Also the DPM's use 4-20mA |
