GE IC670MDL640 Discrete Output Module – Series 90-70 PLC
When a discrete output module fails mid-shift on an automated assembly line, the consequences are immediate and costly: actuators freeze, conveyor belts halt, and production supervisors face unplanned downtime that cascades into missed delivery windows and emergency maintenance calls. In process-critical environments — from automotive stamping to chemical dosing — the output module is the last mile between the controller’s logic and the physical world. Without a reliable, spec-matched replacement, every hour of downtime compounds into measurable revenue loss.
The IC670MDL640 occupies a well-established position within GE’s Series 90-70 rack-based PLC architecture — a platform that has been deployed across heavy industry worldwide since the early 1990s and remains active in thousands of installed bases today. As a 16-point 120VAC discrete output module, the IC670MDL640 handles the high-density switching demands of mid-to-large I/O configurations, making it a standard bill-of-materials item for system integrators maintaining or expanding legacy Series 90-70 installations.

Key Features & Benefits
- 16-Point High-Density Output — Consolidates field wiring into a single slot, reducing panel footprint by up to 50% compared to relay-based discrete wiring panels in equivalent I/O counts.
- Optical Isolation — Galvanic separation between the field-side 120VAC circuit and the logic bus protects the CPU and backplane from voltage transients and ground loops common in heavy industrial environments.
- Hot-Swap Compatible Rack Architecture — Series 90-70 rack design allows module replacement during scheduled maintenance windows without full system shutdown, reducing mean time to repair (MTTR).
- IEC 61131-2 Compliance — Meets the international standard for PLC hardware, ensuring the module performs within defined electrical and environmental tolerances across its rated service life.
- Direct Drop-In Replacement — Identical slot footprint and connector pinout to other IC670MDL-series output modules; no rack modification or re-wiring required for like-for-like swap.
- Broad Load Compatibility — 0.5A per-point rating supports solenoid valves, motor starters (via interposing relays), indicator lamps, and small actuator coils across a wide range of field devices.
Industry & Equipment Applications
- Automotive Manufacturing — Body-in-white welding lines, transfer press controls, and paint shop conveyor sequencing where high-cycle discrete switching is required continuously across multi-shift operations.
- Food & Beverage Processing — Filling machine actuator control, CIP (clean-in-place) valve sequencing, and packaging line reject gate activation in environments requiring reliable 120VAC switching.
- Chemical & Petrochemical — Pump start/stop control, agitator motor sequencing, and safety interlock output circuits in batch processing plants running Series 90-70 DCS-adjacent architectures.
- Water & Wastewater Treatment — Pump station motor control, valve actuator outputs, and alarm annunciator circuits in municipal and industrial water treatment facilities with long-lifecycle PLC installations.
- Power Generation & Utilities — Auxiliary equipment control in turbine balance-of-plant systems, switchgear control panels, and substation automation where Series 90-70 PLCs remain in service.
- Material Handling & Logistics — Conveyor divert gate control, sortation system actuator outputs, and pallet transfer station sequencing in distribution centers using legacy GE automation platforms.
System Integration & Compatible Parts
Upstream Components (CPU & Power):
- IC697CPX935, IC697CPX928 — Series 90-70 CPU modules
- IC697PWR711, IC697PWR724 — Series 90-70 power supply modules
- IC697CHS750, IC697CHS790 — Compatible rack assemblies
Downstream / Peer I/O Modules:
- IC670MDL641 — 16-point 240VAC output module (higher voltage variant; verify field voltage before substitution)
- IC670MDL730 — 16-point 24VDC output module (DC alternative; requires field wiring voltage change)
- IC670MDL310 — 16-point 120VAC input module (complementary input-side pairing)
Substitution Note: IC670MDL641 can substitute for IC670MDL640 only if field devices are rated for 240VAC and the application voltage is confirmed. Always verify output voltage compatibility before cross-substitution.
Our Quality Assurance Process
Every IC670MDL640 unit sourced and shipped by Konmask.com passes through a structured four-step verification process:
- Visual & Physical Inspection — Board-level examination for component damage, corrosion, bent connector pins, and label integrity. Units with evidence of field damage or unauthorized repair are rejected.
- Functional Bench Test — Each output point is exercised under load to verify switching response, isolation integrity, and backplane communication handshake using Series 90-70 compatible test fixtures.
- Firmware & Revision Verification — Hardware revision and firmware version are recorded and disclosed in the shipment documentation to ensure compatibility with the customer’s existing rack configuration.
- Packaging & ESD Protection — Modules are packed in anti-static bags with foam cushioning and clearly labeled with part number, revision, and test date before dispatch.
Available Documentation: Test report, hardware revision record, certificate of conformance (CoC), and original manufacturer datasheet upon request.

Frequently Asked Questions
Q: Is the GE IC670MDL640 compatible with all Series 90-70 rack sizes, and does it require any configuration in Logicmaster or Proficy Machine Edition?
A: The IC670MDL640 is compatible with all standard Series 90-70 rack assemblies (5-slot, 9-slot, and 12-slot configurations). In Logicmaster 90-70 or Proficy Machine Edition, the module must be configured in the I/O configuration table at the correct slot address with output type set to 120VAC discrete. No jumper or DIP switch settings are required on the module itself.
Q: What is the difference between the IC670MDL640 and IC670MDL641, and can I use the 641 as a direct replacement for the 640?
A: The primary difference is output voltage rating: IC670MDL640 is rated for 120VAC field devices, while IC670MDL641 is rated for 240VAC. They share the same slot footprint and connector pinout. Substitution is only appropriate if your field devices and wiring are rated and configured for 240VAC operation. Using a 641 on a 120VAC field circuit is generally safe electrically, but using a 640 on a 240VAC circuit will exceed its rated voltage and risk module damage or unsafe operation.
Q: Can I source a refurbished or surplus IC670MDL640 with confidence, and how do I verify the hardware revision before installation?
A: Yes — surplus and refurbished IC670MDL640 units are a standard procurement path for Series 90-70 maintenance, given that GE (now Emerson) has transitioned this platform to legacy support status. When sourcing, request the hardware revision label (located on the module’s front face or PCB) and confirm it matches the revision documented in your system’s I/O configuration. Konmask.com discloses hardware revision on all units and provides test documentation to support your incoming inspection process.
