9 RELAYS

The αlpha CON 190 features two SPDT non-powered relays; rated for 6A at 110

VAC, 250 VAC maximum. When your process exceeds the set parameters of a

relay set point, the REL 1 or REL 2 indicator will light up.

To set parameters for relay 1 and relay 2, see Setup programs P1.0 and P2.0.

10 TRANSMITTER FUNCTION

If remote data logging is required, a 4-20 mA current loop can be connected. The

current will be proportional to the Conductivity value displayed on the panel and

according to the measurement range selected.

Conductivity Range Range No., R Cell Constant 4 mA current 20 mA current

0.00 – 20.00 µS/cm 1 0.1 0.00 µS/cm 20.00 µS/cm
