– Loop-powered (typical)
Terminal 12-13: Type IB
– external reset (option):
With this function the total can be reset to zero with an external switch. The Total resets only when
the switch
opens
. When a Normally Closed (NC) contact is used, the local clear total function is
disabled and a clear total is only possible with the external reset command.
The input must be switched with a potential free contact to the terminal 12.

Terminal 15-16; alarm / pulse output R3:
This output is designed as a fast output with a maximum frequency of 500Hz. For the use with a
mechanical relay and a continuous signal (pulse) it is recommended to use a maximum frequency of
0.5Hz to prevent an early end-of-life of the mechanical relay.
Type OA:
An active 24V DC signal flow rate alarm output is available with this option.
Max. driving capacity 50mA@24V per output. (Requires power supply type PD/PF/PM).

Type OT:
A passive transistor output is available with this option. Max. driving capacity 300mA@50V DC.
