Isolation Channels
Min = 0°C
Max = 25°C
The temperature range for the isolation circuit is 0 to 25°C. The calibration is
performed by first calculating a good starting point for the offset and span resistors.
Then adjust the 0 point to the minimum point in the ADCC. The last step is to set
the input to 25°C and adjust the span gain to achieve the max value in the ADCC.

Water Slip (Moisture Carryover) Relay Board (OPTIONAL)
Note: For the following instructions, typical applications run each of the relays in
series through the Common and Normally Open (NO) contacts.
A: Computer Status Alarms (External PLC monitoring).
Wire computer status alarms to JP4 & JP2. Wire the Common and Normally
Open Contacts in series to a PLC. If an alarm occurs, one or both of these
contacts will open.
B: Sample Pump Control – Water slip, over-temperature, thermocouple failure
alarms.
Wire the Line (hot) power for the sample pump through terminals through JP3
and JP1. Wire the Common and Normally Open (NO) contacts in series. If
an alarm occurs, one or both of these contacts will open.
The sample pump is now in series with the Water Slip (Moisture Carryover) Sensor
and the Ready/Slip/power failure relay, which will only allow the sample pump to
start if conditions are satisfactory (i.e., no water slip, and safe operating temperature
of the sampling system, and no thermocouple failure).
