Industrial Raspberry Pi MICA-R4 Test Data

In on-site environments where IIoT is required, computer equipment is also expected to be placed under harsh conditions. A wide operating temperature range, excellent resistance to vibration and shock, and EMC performance are required to support such usage. This page introduces data from temperature tests, vibration/shock tests, and EMC tests of HARTING Industrial Raspberry Pi MICA-R4.

Temperature Test

Cold-boot test at -40°C and temperature cycling test were conducted using a thermostatic chamber. Operates even at 100% CPU load in a high temperature 90°C environment. MICA-R4 can be used in harsh temperature environments.

・Cold boot test at -40℃
・Temperature cycling test IEC 60068-2-14:09 Test Nb
 Hold time:3h

(The temperature range for specifications is -20°C to +60°C. Highーtemperatu environments will shorten product life)
