ABB Relion Binary Input Interface Characteristics

The module provides 16 binary input channels with a specified input range of 220-250 VDC. Each channel has 2 mA input current and 22 kOhm input impedance.

Galvanic isolation separates the input and output circuits, limiting direct electrical coupling between the monitored signals and relay contacts.

Individual LED indicators provide local channel status indication during commissioning, signal verification, and maintenance activities.

The relay output is specified for 2 A at 250 VAC, with a stated contact life of 100,000 operations.

The DIN rail mounting arrangement provides a fixed mechanical interface for cabinet installation and panel wiring.

The specified operating temperature range is -25 to 70 deg C, while storage conditions extend from -40 to 85 deg C.

Frequently Asked Questions

Q: What input voltage does the 1MRK000508-BDr04 accept?
A: The specified binary input voltage range is 220-250 VDC, with 2 mA input current and 22 kOhm input impedance.

Q: Does the module provide electrical isolation between circuits?
A: Yes. The supplied specifications state galvanic isolation between the input and output circuits.

Q: What relay output rating is specified?
A: The relay contacts are rated at 2 A at 250 VAC, with a stated contact life of 100,000 operations.

Field Installation Guidelines

Mount the module securely on the specified DIN rail and verify mechanical engagement before terminating field conductors.

Confirm that the applied binary input voltage remains within the specified 220-250 VDC range before energizing channels.

Separate binary input wiring from high-current power conductors where practical to reduce conducted and radiated electrical interference.

Use appropriately rated conductors, terminals, and protective devices for the connected field circuit and relay contacts.

Maintain correct polarity and terminal identification for each DC binary input during installation and commissioning.

Route shielded signal wiring according to the protection system cabinet grounding practice when shielded cables are used.

Connect cable shields according to the system grounding design, avoiding unintended multiple-point connections that can introduce circulating currents.

Verify each channel through its corresponding LED indication after wiring checks and before placing the protection or control function into service.

Do not exceed the specified relay contact rating when connecting external circuits.
