Troubleshooting Guide
b) Calculate maximum allowable loop resistance using the
formula: Loop Resistance (maximum) = V
supply
–7V
For example, a 24V power supply would give a maximum loop
resistance of: 17V/0.020A = 850 ohms.
c) Make sure the power supply is rated for at least 28 mA
times the number of TX93 transmitters being powered. For
example, if the supply is powering five transmitters, the
supply should be rated for at least 140 mA.
0.020A
