Quick Start
Connect an industrial standard power supply across LOOP+ and LOOP- terminals of J1 to power up the board.
Connect the sensor across J3. The current design of the board is configured for 2-wire RTD application. Minor modifications at the
sensor side can be performed to use a 3/4-wire RTD application.
Jumper Descriptions
Table 1. Connector Description and Default Jumper Positions
Jumper Default Position Function
J1 Installed Power pin for Monterey Board. Connect across LOOP+ and LOOP- for power.
J2 Installed
J3 Installed Connect RTD across IN+ and IN-.
J4
Installed across pins
1 and 2
Using a jumper across pins 1 and 2 of J4 uses the MAX44248. This case is used to gain the
input signal.
