Operating as a high-density digital-to-analog converter within the AH500 platform, the Delta Electronics AH08DA-5C provides precise current loop control for demanding industrial process loops. This 8-channel analog output module delivers 16-bit hardware resolution to ensure fine control granularity over 0 to 20mA and 4 to 20mA signal ranges. Engineered with an isolated signal design, it effectively isolates field-side electrical noise from the backplane, ensuring stable CPU operation. The hardware supports an independent interrupt function, hot-swapping under powered backplanes, and a programmable keep-last-value parameter to maintain safe physical states in the event of a controller stop.

| Shipping Weight (Calculated) | 2.0 kg |
This module is designed exclusively for the Delta AH500 high-performance PLC rack architecture. Configuration and channel mapping are managed via Delta ISPSoft software (version 3.0 or higher). If upgrading from legacy hardware, verify that the CPU firmware version supports the hot-swap functionality enabled by the backplane hardware interface.
While internal backplane consumption is low (0.25 W), the 3.7 W external power consumption must be drawn from a stable, low-noise 24 VDC power supply. Ensure that voltage drop calculations account for the maximum current load of all 8 channels running at 20 mA simultaneously. Voltage drops below 20.4 VDC at the module terminal block can degrade D/A linearity and cause diagnostic under-voltage system alarms.
Always use high-quality twisted, shielded pair cabling for current loop connections. Earth the cable shield exclusively at the cabinet ground entry bar; do not ground both ends of the shield to prevent ground loops. If configure-to-run delays occur, check the module interrupt settings in the HWCONFIG utility of ISPSoft to verify execution priority.
Mount the module firmly onto the AH500 series backplane rail, securing the top and bottom latching pins completely.
Unlatch and remove the JIS terminal block to complete the current loop wiring at an external workstation, minimizing mechanical stress on the module housing.
Connect the external 24 VDC power supply directly to the designated power terminals on the block to run the internal output driver circuits.
Reattach the wired JIS terminal block, lock it securely, and apply power. Monitor the LED status indicators to ensure proper system initialization and network configuration.
