6.10 MX1615 amplifier
Up to 16 freely configurable inputs can be connected to the MX1615 amplifier.
It supports:
Strain gauges (SG) or SG−based transducers in
− Full bridge circuit (six−wire configuration)
− Half bridge circuit (five−wire configuration)
− Quarter bridge circuit (two−, three− or four−wire configuration for 120 Ohm or 350 Ohm)
− Normalized voltage ("10 V differential or 0...30V DC unipolar)
− Resistor−based measurement (PT100, resistor, implemented in a quarter bridge arm)
Bridge excitation:
constant DC voltage or 1200 Hz (AC) square wave carrier frequency of 0,5 V; 1 V, 2.5 V or
5 V.
When TEDS or T−ID is used, the measurement channel is automatically parameterized after
connection.

The transducers are connected via 8−pin plug−in terminals (Phoenix Contact FMC
1,5/8−ST−3,5−RF (order no. 1952089)).
The measuring channels are electrically isolated from the MX1615 mains only, however, not
from one another.
