Product Overview

The Planet ISW-504PT is an IP40 industrial unmanaged PoE+ switch featuring 4 10/100BASE-TX 802.3at PoE+ ports and 1 10/100BASE-TX uplink port, with a 1 Gbps switching fabric. It includes a DIP switch for Standard (100m), VLAN (port isolation), and Extend (250m at 10Mbps with 25W PoE) modes, plus integrated 12–48V DC power boost technology delivering a PoE budget of 60W at 12V, 90W at 24V, and 120W at 48V input.


Key Configuration

• Copper ports: 4 × 10/100BASE-TX PoE+ (ports 1–4), 1 × 10/100BASE-TX (port 5).
• PoE budget: 60W @ 12V, 90W @ 24V, 120W @ 48V; per-port output up to 54V DC, 36W max.
• Switch fabric: 1Gbps; throughput: 0.74 Mpps; MAC table: 2K entries.
• Power input: 12–48V DC via 6-pin terminal block with redundant input and reverse polarity protection.
• Dimensions: 50 × 85.1 × 135 mm; weight: 596 g.


Key Features

The ISW-504PT is an industrial PoE+ switch that boosts 12–48V DC input to 54V for PoE output, eliminating the need for special PoE injectors. Its PoE budget varies by input: 60W at 12V, 90W at 24V, and 120W at 48V, powering up to four 30W devices. It features redundant power inputs with an alarm relay (1A @ 24V AC) for failover alerting, and PoE usage LEDs indicate load status.


Technical Context

A DIP switch offers three modes: Standard (100m), VLAN (port isolation with only port 5 accessible), and Extend (250m at 10Mbps with 25W PoE per port). The fanless, IP40 metal case (DIN-rail or wall-mount) operates from -40°C to 75°C with 5–95% RH and stores from -40–85°C, backed by ±5KV ESD and ±5KV surge protection.


Installation Notes

Powered via a 6-pin terminal block (dual DC inputs and alarm relay), the switch consumes 3.7–4.8W standby and 70–136.8W under full PoE load, depending on input voltage. LEDs indicate DC power, fault alarm, per-port link/activity and PoE status, and overall PoE usage. The unit is TAA compliant.
