Type OT
One passive transistor output (D1) is available with a maximum pulse frequency of 500 Hz. Max.
driving capacity 300 mA @ 50 VDC.
● Terminals R1 and R3 are common ground (GND) terminals.
● When retransmit mode is selected the max. frequency is 10kHz with a 50% duty cycle and a
minimum on and off- time of 50µs.

Type OR
One mechanical normally open relay output (D5) is available with a maximum pulse frequency of
0.5Hz. Max. switch power 240 V 0.5 A per output: With the OR option:
● Use power supply terminals P5-P6.
● The required supply voltage is 24 – 27 VDC!
● Be sure that the output frequency does not exceed 0.5 Hz, else the relay life time and reliability
will be reduced significantly.
● The output functionality of digital output D5 corresponds to the functionality of digital output D1.
● When
retransmit mode
is selected, the relays are not activated.

6.4.10 TERMINALS S1-S3: FLOWMETER INPUT
Three basic types of flowmeter signals can be connected to the unit: pulse, active pulse or sine-
wave (coil). The screen of the signal wire must be connected to the common ground terminal (unless
earthed at the sensor itself).
The sensor output should match with the selected flowmeter setting assigned in
