5.4 Retransmission Group (G.RET)
Press SET/ENT key to select retransmission group. (Refer to parameter map.)
This parameter sets the type of retransmission output used. The retransmitting output can
be a 4-20 mA signal based on the PV, or LPS for a loop power supply. See the graphic
below for additional explanation of the retransmission outputs. The default setting is PV.
PV
These parameters are used to scale the retransmitting output. They set the high and low
limits for th e retransmission output scale, as shown below. The retransmitting outputs will
transmit 4 mA at the low limit (RETL) and 20 mA at the high limit (RETH) values.

PV Retransmission Scale
The PV Retransmitting outputs transmit a 4 to 20 mA signal. The 4 mA signal is transmitted when the PV is
equal to the value set in RETL, and 20 mA is transmitted when the PV is equal to the value set in RETH. Note
that RETL and RETH are limited by the maximum and minimum input ranges as setup in INRH and INRL, or
INSH and INSL.
Retransmission Group Parameter Summary
LPS Type Retransmission
LPS (Loop Power Suppy) retransmitting outputs will transmit a 14-18 VDC @ 20 mA power supply output.
