In order to meet the IEC 1000-4-3 levels for RF Susceptibility specified in Appendix A, when this module is present, the system must be mounted in a metal enclosure. 12.1.5 Field Wiring: ALG44 The diagram below shows voltage and current connections for the module. Each channel can be configured independently as a voltage or a current channel, not both simultaneously. Terminal Signal Definition 1 24VIN User Supplied +24Vdc Input 2 JMP1 Jumper terminal for connecting 250W sense resistor for CH1 System Manual Section 13 GFK-2314T Sept. 2019 Analog Mixed I/O Modules 583 12 -CH3 Negative connection for differential analog input channel 3 ground connections for cable shields 12.1.6 Input Scaling: ALG442 Resolution per bit depends on the configured input or output range as shown in the table of module specifications. The module scales each current and voltage input to a value in counts for the CPU. Configured Range Scaled +32000. The Enhanced range automatically provides 4 to 20 mA range scaling. Negative digital values are provided for input current levels between 4 mA and 0 mA. This creates a low alarm limit that detects when the input current falls from 4 mA to 0 mA, providing open-wire fault detection in 4 to 20 mA applications. If the value exceeds 32,000 it is truncated to 32,000. 0 0V to +10V Inputs Counts 32000 0 +10V Figure 332: Input Voltage Scaling ALG442 4 Counts Current (mA) 4 to 20mA Range 20 0 32000 0 to 20mA Range Figure 333: Input Current Scaling ALG442 If the current source is reversed into the input, or is less than the low end of the current range, the module inputs a data word corresponding to the low end of the current range (0000H in %AI). If an input is out of range (greater than 20 mA), the A/D converter adjusts it to full scale (corresponding to 7FFFH in %AI). 12.1.7 Output Scaling: ALG442 The module scales counts data received from the CPU to a current or voltage value for each output.
