Type OT
Two passive transistor outputs (D1 and D2) are 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 minimum on and off-time is 50 μs.

Type OR
One mechanical normally open relay output is available with a maximum pulse frequency of 0.5 Hz.
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 and D6 correspond to the functionality of digital
outputs D1 and D2, respectively
● When retransmit mode is selected, the relays are not activated.

6.4.10 TERMINALS S1-S3 SIGNAL A AND S4-S6 SIGNAL B: 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
