TRANSCEIVERS and MODELS

1) DMM3 LON FTT10
FTT-10A Free Topology Twisted Pair Transceiver supports polarity-insensitive star, bus, and loop wiring, freeing the system installer from the need to wire using a bus topology. Free topology wiring reduces the time and expense of system installation by allowing the wiring to be installed in the most expeditious manner. It also simplifies network expansion by eliminating restrictions on wire routing, splicing, and node placement.

2) DMM3 LON RS485
The RS485 twisted pair is one of the most popular transmission media. This model allow the direct connection of the DMM3 in such kind of applications.

Any other type of transmission media requires the utilization of a gateway

OUTPUT

One digital output for alarm or pulses.
The alarm setup includes the association of the measure, thresholds, hysteresys % and delay time. The pulses mode allows the setting of the measure, the number of pulses per unit , the pulse width 100 msec or 20 msec.
