Product Introduction

is a high-current sourcing DC discrete output module for Series 90-30 PLC, widely used in machine automation, packaging and hydraulic/pneumatic valve control.

Important Module Family Distinction

1. : 16-point, 2A per channel sourcing output (high current DC)
2. IC693MDL740: 16-point, 0.5A per channel sourcing output (lower power)
3. IC693MDL940: Relay dry contact output module
4. IC694MDL730: Equivalent module for IC694 serial expansion racks (form factor incompatible)

Four independent common groups allow different DC potentials on separate groups, improving wiring flexibility. Group isolation suppresses cross-group noise interference.

Critical Wiring Note: Sourcing (source) output matches sinking (NPN) field loads. For sinking PLC outputs (sink type), select MDL750 series.

This module is not HART-capable, only for discrete on/off DC loads.

 

QA & Testing SOP (Transparency Building)

1. Incoming Inspection: Verify part marking. Inspect backplane gold pins for oxidation/bending; check module housing integrity.
2. Live Testing: Mount onto validated Series90-30 backplane. Apply rack power and external 24VDC field supply. Toggle each channel, verify output voltage under resistive load, check LED status, run continuous 24-hour switching stability test.
3. Electrical Testing: Monitor backplane 5V rail stability. Insulation resistance ≥10MΩ between field terminals and chassis protective ground.
4. Documentation: Photograph terminal wiring layout before disassembly; record hardware revision.
5. Final QC & Packaging: Place unit inside anti-static shielding. Attach dated QC test tag confirming channel switching validation prior to shipment.

 

Installation Pitfalls & Guide

❗ No Hot Swap Support: Series90-30 I/O modules cannot be hot swapped. Full rack power shutdown mandatory before removal. ❗ External DC Field Supply Mandate: Output drive power comes from external field 12/24VDC; backplane power only for module logic. ❗ Current Budget Control: Do not exceed 2A per channel / 4A per common group rating; overload accelerates internal power device degradation. ❗ Sourcing Load Matching: Designed for NPN sinking loads; incorrect wiring will prevent load actuation. ❗ External Fusing Recommendation: No built-in channel fuses; add branch fuses for short-circuit protection. ❗ Conformal Coated Variant: IC693MDL730CA for humid/corrosive environments; electrically identical. ❗ Inductive Load Protection: Install flyback diodes across solenoid coils to absorb inductive kickback. ❗ ESD Risk: Static discharge damages output power semiconductors leading to channel dropout or permanent failure.

Replacement Guide

1. Pre-install: Lockout-tagout rack power; back up PLC I/O configuration. Photograph slot arrangement and field wiring mapping.
2. Removal: Disconnect all field output wiring, unlatch module and slide straight out without twisting backplane pins.
3. Install: Seat new into original slot, replicate all field wiring connections.
4. Power-on Test: Restore rack power; confirm all channel LED operation, verify main CPU can toggle all %Q discrete outputs normally.

 

FAQ

Q: Does support hot swapping? A: No. Series90-30 I/O modules do not support hot swap. Full rack power shutdown required.

Q: What is the difference between and IC693MDL740? A:

• : 2A per channel high-current sourcing output
• IC693MDL740: 0.5A per channel standard sourcing output Pinout and form factor identical; check load current before interchange.

Q: Can I install directly into RX3i main IC695CHS007 rack? A: No. Native Series90-30 module. RX3i usage requires remote serial expansion rack with IC695LRE001.

Q: What is sourcing (positive logic) output? A: Module supplies positive DC voltage to the load; load return connects to DC negative (GND). Suitable for NPN field sensors and solenoids.

Q: Can different voltage potentials be used on separate groups? A: Yes, each group is isolated; maintain consistent voltage within one common group.

Q: Will saved I/O configuration automatically work after replacement? A: Discrete channel configuration resides in the PLC project. After replacement, verify all output points can be toggled normally.
