Two potential-free contacts programmable as limit switches for
measuring values, controllers or timer for system cleaning with au-
tomatic hold function. Both contacts can be used as normally open
or normally closed.
Maximum load: 1 A/250 VAC
One potential free contact.
Alternatively:
 Open during normal operation, closed on error and loss of
power.
 Closed during normal operation, open on error and loss of
power.
Summary alarm indication for programmable alarm values and in-
strument faults.
For potential-free contact to freeze the measuring value or to inter-
rupt control in automated installations (hold function or remote-off).
Possibility to interrupt the measurement by activating the input. See
Program List and Explanation,
No data loss after power failure. All data is saved in non-volatile
memory. Over voltage protection of in- and outputs.Galvanic sepa-
ration of measuring inputs and signal outputs.
 USB Interface for logger download.
 Third signal output (can be used in parallel to the USB interface)
 RS485 with Fieldbus protocol Modbus or Profibus DP
 HART interface
Optional pH measurement is possible (pH correction or calibration).
The AMI Relay Box is designed for the direct power supply and ac-
tivation of dosing devices which are controlled with an AMI trans-
mitter, e. g. to connect two solenoid valves or one motor valve for
disinfectant additions.
An optional Cleaning module is available.
