8030-ROM-121. Symax Class 8030 Type ROM-121 Analog Output Module. Selected output ranges 1-5 VDC, 0-10 VDC, +10 to -10 VDC, 4-20 mA. Accuracy is plus or minus 0.15% at 25C, plus or minus 0.5% (of full scale) over 0-60C temperature range. Span and zero require initial user calibration. Resolution is 11-bit, or 1 part in 2048 (full scale range in the storage register of 0-9999). Negative storage register values correspond to the minimum output of the selected range; values in excess of 9999 are represented as the maximum output for the selected range. The conversion rate output channel reflects register values within 10 msec. of module receiving updated information (40 msec. for all 4 channels). Isolation is 200V channel to ground (or analog output circuit to digital logic circuit) continuously applied. 1500V transient isolation. No analog channel to channel isolation. 10mA (voltage settings), 600 ohms (current settings) drive capabilities. User output options on CPU Halt are HOLD (maintain the last value received while in RUN) or RESET (go to the minimum output for the selected range within 40 msec. of CPU HALT). Short circuit protection. Requires 1500 mA current draw from Symax power supply connected to the rack.
