Assembly & Wiring Guidelines

DIN-Rail Mechanical Assembly

• Fasten the module onto a standard 35 mm DIN rail (TH35-7.5) connected adjacent to the CPU or base unit.
• Engage the mechanical locking slide to secure ground bonding between the chassis and DIN rail.

Field Signal Cabling Rules

• Wire field inputs using 24 VDC sink or source wiring methods into the 1-wire terminal connections.
• Keep low-voltage digital signal cables isolated from high-power AC lines to prevent capacitive noise coupling.

Technical Support FAQ

• Can the DI561 digital input module be replaced under live system power?

  No, 24 VDC power must be completely isolated from the bus prior to module installation or removal.

• What signal delay is introduced by the input filter circuitry?

  The hardware input filter introduces a standard signal delay time rated at 8 ms.

• Does each channel require separate common power wiring?

  No, the module utilizes a simplified 1-wire field termination topology for input signals.

• What is the nominal current drawn by each digital input terminal?

  Each digital input channel draws approximately 5 mA under nominal 24 VDC excitation.

• What physical voltage range is recognized by the input channels?

  The discrete inputs accept standard 24 VDC voltage signals within an operating limits window of 0 to 30 VDC.

• Are sink and source sensor outputs both compatible with this module?

  Yes, the input channels are designed to accept both sink and source 24 VDC field wiring configurations.

• What ambient temperature limits apply during continuous module operation?

  The module operates reliably within an ambient temperature environment ranging from 0 deg C to +60 deg C.

• What storage conditions are required when the unit is not in service?

  Store the module inside its protective packaging at ambient temperatures between -40 deg C and +70 deg C.
