Input Specifications
Value
Power Requirements
Bus +5 V (4.75 V to 5.4 V)
100 mA maximum
Bus +24 V (19.9 V to
26.4 V)
20 mA maximum
Power Dissipation within
module
1 W max
Inrush current
Less than 150 mA at 5 V; less than 400 mA at 24 V
Fusing
UL approved and properly sized SMD fuse or properly sized
fuse resistors on both the 24 VDC and 5 VDC power supply
lines.
Fault detection
Over/under range for all types
Open Circuit detection
Note: Thermocouple open circuit (open wire) will be
periodically checked using the PGA burnout current. This
saves on component cost and increases the Voltage Input
impedance.
Wire Installation
Wire size
#16 to #28 AWG
Wire Strip Length
0.375 in.
Recommended Tightening
Torque:
0.25 N-m (2.2 in-lbs.)
