SYCLOPE COOLTouch
®
has ten inputs:
 1 Input RI1 RTD isolated for (Pt100 / Pt1000)
 1 Input RI2 isolated for conductivity
 2 Inputs AI1 & AI2 4-20mA isolated for temperature, chlorine, bromine, etc measure
 5 Inputs DI1 to DI5 digital for sensor.
 1 Input SI1 serial for UART 5V TTL
a) PT100 / Pt1000 input RI1
Connection of the sensor on RI1:
 Preferably use a shielded coaxial cable.
 Connect the sensor (+) strand to the RI1 + (1) connection.
 Connect the sensor (-) strand to the RI1 - (2) connection.
 Tighten the cable gland to seal.
b) Conductivity input RI2
Connection of the sensor on RI2:
 Preferably use a shielded coaxial cable.
 Connect the sensor (+) strand to the RI2 + (3) connection.
 Connect the sensor (-) strand to the RI2 - (4) connection.
 Tighten the cable gland to seal.
