How many current inputs does Metso IOP302 provide?

Metso IOP302 provides sixteen common 4-20 mA analog input channels in its DPU4E operating mode.

Which address arrangement applies when Metso IOP302 operates with DPU4A/B?

The DPU4A/B configuration assigns sixteen addresses to Metso IOP302 and makes fifteen input channels available.

What changes when Metso IOP302 is configured for DPU4E?

DPU4E operation reduces the Metso IOP302 address requirement to two while enabling all sixteen channels.

How does jumper W6 configure Metso IOP302?

Jumper W6 selects the DPU interface: the installed position is for DPU4A/B, and the removed position is for DPU4E.

Which frequency setting is controlled by W1 on Metso IOP302?

W1 configures Metso IOP302 for 50 Hz rejection when installed and for 60 Hz rejection when removed.

How is transmitter loop power distributed by Metso IOP302?

The backplane supplies 24 V transmitter power to Metso IOP302, and an individual electronic fuse protects each channel's loop-power path.

What conversion performance is specified for Metso IOP302?

Metso IOP302 uses sigma-delta oversampling with one A/D per channel, 15-bit-plus-sign resolution and a 20 ms scan rate.

Which checks complete commissioning of Metso IOP302?

Commissioning should confirm the DPU mode, W1/W6 positions, P2/P3 channel mapping, Active LED behavior, diagnostic status and every used 4-20 mA input.

Information

Overview Manuals Common Applications Product Precautions

Within a maxPAC input subsystem, Metso IOP302 conditions current-loop signals, performs channel conversion and delivers the resulting data to the selected DPU architecture.

Sixteen common 4-20 mA analog input channels
Individually fused 24 V transmitter loop power
DPU4A/B and DPU4E operating modes selected by jumper
Power-up diagnostics with periodic online self-calibration

The installed DPU determines the address and channel arrangement: DPU4A/B operation uses sixteen addresses for fifteen channels, while DPU4E operation uses two addresses for all sixteen channels. The W1 and W6 jumpers, P2/P3 field connections, loop-power path and bus position must therefore be preserved during replacement. Commissioning should confirm the Active LED state, diagnostic codes, channel readings and the intended 50/60 Hz rejection setting.

Important Notice: Confirm the complete IOP302 marking, installed DPU type, W1/W6 jumper positions and every P2/P3 field connection before energization.

Metso IOP302 Manuals & Downloads

Metso IOP302 Official Technical Reference Excerpt (PDF)Metso IOP302 Installation & Commissioning Guide (PDF)

The first document contains the applicable manufacturer reference pages for this exact product; the second organizes preparation, wiring, diagnostics and handover checks.

Sixteen-loop current acquisition

Collects sixteen common 4-20 mA field signals through one maxPAC analog input module.

DPU4E input expansion

Provides all sixteen channels while occupying two bus addresses in the documented DPU4E mode.

DPU4A/B cabinet service

Supports the legacy operating mode with fifteen available channels and sixteen assigned addresses.

Controlled analog-module replacement

Restores recorded jumper, address and P2/P3 wiring arrangements before functional testing.

Read the applicable Metso instructions before work. Verify IOP302 and the installed system configuration before isolation or replacement.

Record the complete Metso IOP302 marking, rack position and DPU type.

Place every connected 4-20 mA loop and the controller in the approved maintenance state.

Isolate the 24 V system and transmitter-loop supplies before moving field wiring.

Label all P2 and P3 conductors so channels 1-16 retain their recorded assignments.

Match W6 to DPU4A/B or DPU4E operation and restore the correct bus-address plan.

Set W1 for the installed 50 Hz or 60 Hz rejection requirement.

Inspect the individually fused loop-power paths, connectors and channel wiring before energization.

Review the Active LED, diagnostic code behavior and every used channel value before release.

Technical notes

IOP302 uses one sigma-delta converter per channel with 15-bit-plus-sign resolution and a 20 ms scan rate. Published performance includes ±0.1% accuracy at 25 °C, 300 Ω input impedance and 60 dB normal-mode rejection at 50/60 Hz. The module draws 125 mA from the 24 V system supply, so subsystem power budgeting should include that load separately from field-transmitter demand.
