Overview Manuals Applications Relay Performance Environmental Limits Output Safety

Features:

  • Provides 16 AC relay output channels for discrete switching functions.
  • Switches compatible field loads through individually controlled relay contacts.
  • Integrates discrete output commands with the Nexus OnCore architecture.
MDO53 combines output type of AC relay, channels of 16, and i/o function of Discrete output switching in the Nexus OnCore platform.

It switches sixteen discrete output channels through AC-relay output circuitry. This role connects the Nexus OnCore 16-Channel AC Relay Digital Output Module to the surrounding Nexus OnCore architecture.

Before commissioning, verify relay-contact voltage and load requirements; match the complete MDO53 regional suffix; and de-energize outputs before connecting or disconnecting.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • Switches sixteen discrete field-output circuits within a Nexus OnCore control system.
  • Interfaces relay-driven actuators and annunciation loads with the OnCore control architecture.
  • Supports certified panel-mounted process-control installations that use the specified relay-output hardware.
  • Receives nominal 24 VDC operating power from the Nexus OnCore panel supply.
  • Consumes up to 11.0 W under the specified sixteen-channel relay-output configuration.
  • Rates each relay channel for connected loads up to 8 A at 30 VDC.
  • The relay-output assembly is certified for ambient operation from -20 to +50 degrees C.
  • Applies Class I Division 2 and Zone 2 markings to the approved relay-output installations.
  • Requires a minimum IP54 panel enclosure when installed under the stated ATEX conditions.
  • Verify relay-contact voltage and connected-load requirements before energizing the output circuits.
  • Match the complete regional part-number suffix with the module installed in the existing assembly.
  • De-energize every affected output before connecting, disconnecting, or replacing field wiring.
Description
General Electric MDO53 is a sixteen-channel AC-relay digital output module for the Nexus OnCore platform. The module uses 24 VDC supply power, lists an 11.0 W maximum requirement, and provides discrete output switching through relay circuitry.

Its channels translate OnCore control decisions into isolated switching actions for compatible field circuits. Relay outputs are suited to applications that require contact-based commands rather than continuous analog references.

Before energizing a replacement, confirm contact utilization, field voltage, load current, suppression, channel mapping, and terminal wiring. Apply the certified enclosure and environmental restrictions specified for the installed module.

Technical notes
For MDO53 service work, follow these controls: de-energize outputs before connecting or disconnecting; verify relay-contact voltage and load requirements before installation or replacement.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which switching technology is used by MDO53 outputs?
MDO53 provides sixteen discrete output channels using AC relay switching in the Nexus OnCore range.
What load data must be compatible with MDO53 relay channels?
Confirm contact voltage, steady and inrush current, load type, channel allocation, suppression, isolation, terminals, and regional suffix.
Where can MDO53 be applied in a Nexus output scheme?
It can switch compatible actuators, contactors, solenoids, alarms, or annunciators under the documented relay limits.
Which load schedule should be sent when requesting MDO53?
Provide the complete suffix, channel-by-channel load schedule, terminal drawing, certification label, condition, quantity, and destination.
Why is the transistor-output MDO55 not an MDO53 replacement?
MDO55 uses source-transistor outputs, so its electrical behavior, load interface, wiring, diagnostics, and protection are different.
What protection details belong with the MDO53 documentation?
Use the GE Vernova declaration, relay-contact ratings, fuse or breaker design, suppression method, enclosure plan, and output schedule.
