NORDAC SK700E-551-340-A I/O Expansion Module | Analog & Digital Signal Extension | SK700E Inverter Platform
Engineering Background
The NORDAC SK700E series is Nord Drivesystems’ flagship compact frequency inverter platform, widely deployed across material handling, conveyor, pump, and fan applications in industrial automation. The SK700E-551-340-A is a dedicated I/O expansion module engineered to extend the signal interface capability of SK700E inverter units, enabling more complex control architectures without external signal conditioning hardware.
Product Positioning
Designed for OEM machine builders and system integrators who require additional analog and digital I/O channels beyond the base inverter’s native interface. This module slots directly into the SK700E option bay, maintaining the compact footprint and DIN-rail compatibility of the host drive. It is the preferred choice for procurement engineers specifying Nord-based drive systems in multi-axis or process-critical environments.

Engineering Advantages
- Seamless Integration: Plug-in design eliminates external wiring between drive and I/O terminal blocks, reducing panel footprint and wiring errors.
- Expanded Signal Capacity: Adds analog and digital channels without requiring a larger or more expensive drive model.
- Nord Ecosystem Compatibility: Fully parameterized via NORDAC ACCESS or POSICON software tools — no third-party configuration required.
- Robust Industrial Design: Conformal-coated PCB for resistance to humidity, dust, and vibration in demanding plant environments.
- Reduced BOM Complexity: Eliminates need for separate signal isolators or marshalling terminals in many applications.
System Architecture & Signal Flow
The SK700E-551-340-A installs into the designated option slot on the SK700E inverter. Once seated, the module is automatically recognized by the drive firmware. Signal mapping is configured via parameter sets in the NORDAC ACCESS software. Analog inputs accept 0–10 V or 0/4–20 mA signals (software selectable); digital inputs are 24 VDC PNP/NPN compatible. All I/O channels are galvanically referenced to the drive’s internal logic supply, ensuring noise immunity in variable-speed drive environments with high dV/dt switching transients.

Technical FAQ
Q: Is the SK700E-551-340-A compatible with the SK700E-221 and SK700E-371 base units?
A: Compatibility depends on the specific SK700E variant’s option slot configuration. Please provide your full drive model number for confirmation before ordering.
Q: Can this module be used with NORDAC FLEX or SK500E series?
A: No. This module is designed exclusively for the SK700E platform. Different series use different option module form factors.
Q: What software is required for parameterization?
A: NORDAC ACCESS (free download from Nord Drivesystems) is the standard tool. The module parameters are accessible within the standard SK700E parameter set — no additional license required.
Q: Do you provide a warranty?
A: Yes. Konmask provides a 12-month warranty on all verified OEM parts against manufacturing defects. Contact support@konmask.com for warranty claims.
Q: Can you supply multiple units for a project BOM?
A: Yes. Volume pricing is available for project quantities. Contact us with your BOM and required delivery schedule.
