Eight non-differential inputs, each sampled at 160 ms per channel plus one controller cycle time. Total error is +/-1 %FS, with repeat accuracy +/-0.4 %FS. Accuracy at 25 °C is +/-0.2 % of full scale, drifting at +/-0.01 %FS/°C. The external 24 V DC supply draws 45 mA; internal 5 V bus draw is 60 mA. Insulation between I/O and internal logic is rated 2500 V via photocoupler. Use shielded cable for the sensor lines.
