8 RELAYS
The Alpha COND 200 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 lights up.
To set parameters for relay one and relay two, see Setup programs P1.0 and P2.0.
9 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.
