• Connect the 2350 cable directly to a loop device as shown.
4. Digital
(S
3
L) Wiring
• All models of the 2350 provide Digital (S
3
L) output when powered with 5 VDC.
• Connecting the SHIELD to a direct Earth ground may reduce electrical noise interference.
• The maximum Digital (S
3
L) cable length is dependent upon the instrument to which the sensor is connected. Consult the instrument
manual for details.
• Connect the 2350 cable directly to
Digital (S
3
L) I/O terminals.
• When the 2350 includes a junction
box, connect the 2350 terminals to any
Digital (S
3
L) I/O port as shown.
• When the 2350 includes a junction box, connect the 2350
terminals to a loop device as shown.
5. 4 to 20 mA Loop Wiring
• The 2350-3 provides a 4 to 20 mA loop output when powered with 24 VDC.
• Connecting the SHIELD to a direct Earth ground may reduce electrical noise interference.
• Red wire is not used, do not remove the heat shrink. See Section 6, 4 to 20 mA Span Adjustment.
