Current: 0 to 20mA, 4 to 20mA Voltage: ±10 Vdc, 0 to 10 Vdc PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Modules with HART Communications 518 Backplane Power Requirements For integer in a 32-bit field Analog Update Rate (Determined by I/O scan time, application dependent.) 16ms with HART (approximate, all eight channels) 8ms without HART (approximate, all eight channels) HART Data Scan Time (in seconds) The HART data scan can consist of up to two acquisition cycles (similar but asynchronous to the analog scan time). Each cycle includes a specific set of channels. For ALG728: 1-4, 5-8 are separate channel groups. Total HART scan time depends on the number of acquisition cycles in the scan, number of retries, enabling/disabling of slot variables, and use of pass-through commands. If slot variables are enabled, update times are doubled. 1 HART device in group Each HART Data channel updates every 0.7 second (typical) 2 HART devices in group Each HART Data channel updates every 1.9 seconds (typical) Output Over-voltage Protection Current outputs only: -30V for 60 seconds, +30V for one hour Calibrated Accuracy68 Accurate to within 0.15% of full scale at 25°C Accurate to within 0.30% of full scale at 60°C Output Load Reactance Current: 10µH maximum, Voltage: 1µF maximum 68 In the presence of severe RF interference (IC 801-3, 10V/m), accuracy may be degraded to ±1% FS.

Module Status Reference Length 0 Read Only. The number of bits (0 or 32) required for the Module Status data. Default is 0, which means mapping of Module Status data is disabled. Change this to a non-zero value to enable Module Status data mapping. 11.3.5.1.1 Analog Output Commanded Feedback The module returns a copy of the analog output data received from CPU in its corresponding channel analog input shared memory. Output Feedback can be monitored to check the values being sent to the channels. The data is in the same scaled format as the output data for each channel. During normal operation, this feedback data should match the actual output data after one or more PLC scans of module inputs. During faults, ramping, over-range, and clamping conditions, the analog output data may differ from the commanded output. 11.3.5.1.2 Over-Temperature If Over-Temperature is enabled, the module Mode The following table lists wiring connections for Return (IRTN13) 33 16 No Connection Channel 7 IN- No Connection 34 17 No Connection Channel 8 IN+ No Connection Channel 8 Current Return (IRTN15) 35 18 No Connection Channel 8 IN- No Connection 36 PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Modules with HART Communications 514 There are no shield terminals on these modules. For shielding, tie the cable shields to the ground bar along the bottom of the backplane. M3 tapped holes are provided for this purpose. All the common terminals are connected together internally, so any common terminal can be used for the negative lead of the external power supply.
