Extron IPL EXP PDU4H (part number 60-1956-01) — a half-rack IP Link power expansion interface that adds four independently switched AC outlets and current sensing to a control system.

The PDU4H switches four IEC outlets under program or panel control, with per-outlet manual control contact inputs for local override and a single relay for auxiliary switching. Current sensing on the AC output (0-12 A, 100 mA resolution) lets a control system monitor connected-load power draw, and built-in surge protection guards the outlets and any downstream equipment.

Key Capabilities

• 4 independently switched IEC AC outlets with current sensing (0-12 A)
• 4 manual control contact inputs for local override of each outlet
• 1 normally open relay for auxiliary switching
• Built-in surge protection (30,000 A peak impulse current rating)
• Internal power supply, half-rack metal enclosure

Where It Is Used

Equipment racks that need to power-cycle displays, amplifiers, or other AC-powered gear from a control system use the PDU4H's four switched outlets and current sensing to automate power sequencing and monitor load status.

Specifications at a Glance

• Switched AC Output: 4 IEC outlets, 120/240 VAC, current sensed 0-12 A
• Manual Control Inputs: 4 contact closure inputs; Relay: 1 normally open
• Memory: 512 MB SDRAM / 512 MB flash
• Enclosure: Metal, half rack wide, internal power supply
