Refer to Output Defaults in this section for more information. Module does not support insertion into or removal from an RX3i Universal Backplane which is under power (see Hot Insertion and Removal Not Supported, Section 2.6.4.2). 10.2.1 Isolated +24Vdc Power If the module is located in an RX3i Universal Backplane, an external source of Isolated +24Vdc is required to provide power for the module. The external source can be connected via the TB1 connector on the left side of the backplane or directly on the terminal block of this module. If this module is located in an Expansion or Remote backplane, its primary power source can be either the Isolated +24Vdc from the backplane power supply or an external Isolated +24Vdc power supply connected to the terminal block of this module. If the external source is set between 27.5-30 Vdc, it takes over the load from the Isolated 24Vdc system supply. Note that an external source should be used if it is desired to maintain hold last state operation during a loss of backplane power. 10.2.2 LED The Module OK LED is ON when the module power supply is operating.

In this range, a count of 0 corresponds to 4 mA and a count of 32000 corresponds to 20 mA. In the 0 to 20 mA range, the module scales output data so that each 800 counts represents 0.5 mA. In this range, a count of 0 corresponds to 0 mA and a count of 32000 corresponds to 20 mA with each 800 counts representing 0.5 mA. PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Output Modules 437 If the module receives negative data from the CPU, it outputs the low end of the range (either 0 mA or 4 mA). If a value greater than 32767 is received, it is not accepted. 10.2.5 Field Wiring: ALG391 To minimize the capacitive loading and noise, all field connections to the module should be wired using a good grade of twisted, shielded instrumentation cable. The shields should be connected to GND on the user terminal connector block. The GND connection provides access to the backplane (frame ground) resulting in superior rejection of noise caused by any shield drain currents. If no jumper is installed, the module performs as a current source. If the jumper is present, the module performs as a voltage source.
