Advantech AWS-825PB HMI Operator Interface Panel

Advantech AWS-825PB is an industrial HMI operator interface panel built around a passive backplane that accepts four ISA slots, two PCI slots, and a CPU slot, enabling configurable expansion for automation tasks. The front panel offers two keypad options: a 39-key operator keyboard or a 10-function plus 10-macro keyboard, with a pre-wired 5-pin DIN keyboard connector protected by dust covers on both front and rear. A 260 W AC power supply supports input voltages from 85–130 VAC or 180–260 VAC at 47–63 Hz and provides +5 V up to 25 A, +12 V up to 9 A, -5 V up to 0.5 A, and -12 V up to 2 A; an optional -48 VDC input version (310 W) supports -38 to -58 VDC with +5 V up to 30 A, +12 V up to 10 A, -5 V up to 1 A, and -12 V up to 5 A, with MTBF rated at 100,000 hours. Safety approvals include UL/CSA/TUV. The AWS-825PB is designed as a panel-based industrial workstation used in factory automation, and a touchscreen variant is offered as AWS-825PB-T, which adds touchscreen control via a PC-bus interface. In current catalogs, the AWS-825PB is shown as discontinued by the manufacturer, though it remains referenced in distributor listings as AWS-825PB and AWS-825PB-T.
