Features:
- Universal digital input coverage across four documented voltage services
- Harmony rack connection through the I/O expander bus
- Discrete field-to-controller interface for legacy control cabinets
IMDSI22 provides one Harmony rack module identity for multiple digital-input voltage families.
Its universal label refers to the supported electrical services, not to unrestricted termination or wiring substitution.
A reliable retrofit starts with the cabinet point schedule and a measured field-voltage check.
Availability of IMDSI22 is subject to Apter Power's current inventory and sourcing confirmation.

Voltage-family review
- 24 VDC: verify source, common, and field-contact arrangement.
- 48 VDC: retain the documented circuit segregation.
- 125 VDC: confirm cabinet safety and wiring practices.
- 120 VAC: preserve AC separation and approved terminal design.
Rack communication
- Slot identity: record the mounting-unit position.
- Bus connection: inspect the I/O expander-bus path.
- Controller mapping: reconcile point addresses before startup.
- Diagnostics: review module status before field testing.
Legacy input handover
- Conductor tags: label every field wire before removal.
- Termination match: confirm the existing unit and cable.
- State proof: test open and active field conditions.
- Drawing update: record any corrected terminal assignment.
