Selection Notes

Pick the HMISCU8B5 over the 3.5-inch digital-only model in the same range when the application needs analogue I/O — its 4 analogue inputs (including 2 RTD channels) and 2 analogue outputs handle temperature or process signals the smaller, digital-only model cannot. The larger 5.7-inch screen also suits applications with more operator-facing data per page, at the cost of roughly 60% more current draw (24 W vs 15 W).
