Retransmit devices:

The process value assosiated with relay 1 may be re-transmit
as a 0-20mA or 4-20mA signal. This signal may represent any
of the operating modes including COUNTER modes. If relay 1 is
configured for counting, the loop output will increase as the
number of pulses counted increases.


 

These devices incorporate 2 relays. If relay 1 is configured for COUNTING, relay 2 may be configured as a COUNTER, RPM, Freq, PPh monitor. If relay 1 is configured for a mode other than COUNTER, then both relay 1 and 2 are automatically configured for the same function, ie  The device cannot simultaneously montor RPM and Freq. or RPM and PPh.
