The 1756-PH75 circuit has an isolation voltage of 250V between power input-to-backplane fitted with a reinforced insulation type tested at 3500V DC for 60s. It uses 2.5mm2 stranded or solid copper wire with 1.2mm (3/64in) thick insulation rated at 90 °C (194 °F) and with a conductor torque of 0.8 N•m (7 lb•in). It is stored at a non-operational temperature range of -40-85 °C and when operational, it ranges between 0 °C and 60 °C at an IEC 60068-2-30 tested 5-95% non-condensing relative humidity. The 1756-PH75 is designed to withstand and sustain an operational shock of 30G and a vibration of 2G, and in non-operating mode, it can stand a shock of 50G. The 1756-PH75 weighs 2.10 pounds and has a total volume of 5.51in x 4.41in x 5.71in.
