Digital Outputs
MagFlux ® has two digital outputs - DO 1 with an opto (light triggered)
relay and DO 2 with a mechanical relay.
They can both be programmed for the following functions:
- high and low flow alarms
- pulse output for counters R Totalizer Forward and Reverse
- batch 1 and batch 2 counters
- system error alarm
- empty pipe alarm
- flow direction indication
Opto Relay (DO1)
Terminal Designation
DO 1 Com Max. 50 V DC /120 mA
DO 1 NO
Mechanical Relay (DO2)
Terminal Designation
DO 2 Com Max. 50 V DC /1 A
DO 2 NO
DO 1 shares the common terminal (Com) with DI.
