ABB AR C093 AE01 HIEE300690R0001 Relay Output Card

Products Description

Core Features & Advantages

• SPDT Relay Flexibility for Retrofit Applications: The module’s standout feature is its 2 × SPDT (Single-Pole Double-Throw) relay outputs. Unlike transistor outputs that are limited to DC voltage levels, SPDT relays provide both normally open (NO) and normally closed (NC) contacts, allowing direct interface with AC or DC external circuits. This makes the card particularly useful for legacy production line retrofits where existing control circuits operate at various voltage levels.

• High-Voltage Isolation for Harsh Environments: With 2.5 kV AC isolation between the digital I/O, outputs, and power supply, the card effectively blocks ground loops and common-mode interference from entering the drive’s control side. This is critical in industrial environments where variable frequency drives and motors generate strong electromagnetic noise.

• Long Relay Life for High-Frequency Switching: The onboard relays are rated for ≥10⁷ mechanical operations and ≥10⁵ electrical operations at rated load. This ensures reliable performance in applications requiring frequent contact switching, such as cycle-dependent alarm signaling or sequence control, without premature contact wear or sticking.

• Simple DIP Switch Configuration: Function assignment is set via on-board DIP switches, with activation performed through the drive’s parameter settings using DriveWindow or Drive Composer software. This eliminates the need for complex wiring changes and allows quick adaptation to different application requirements.

• Compact Option Board Design: As an option board that plugs into the RMIO interface board (SLOT 1 or SLOT 2) of an ACS800 drive, the card expands I/O capability without requiring additional external hardware. It cannot operate standalone—it must be installed in a compatible drive to function.

Typical Applications

The AR C093 AE01 is primarily used to extend relay output capability in ABB drive systems where the standard I/O is insufficient:

• ACS800 Drive Systems: Adding alarm contact outputs and auxiliary control signals for fault indication, run status, and external interlocking

• Legacy System Retrofits: Providing relay-isolated outputs for interfacing with existing plant control circuits at various voltage levels

• Industrial Automation: General-purpose relay switching for solenoids, indicator lamps, and auxiliary contactors in manufacturing and process control

Frequently Asked Questions (FAQ)

Q1: What is the primary function of the AR C093 AE01?
A: It is a relay output option board that extends the I/O capability of ABB ACS800 drives by providing 2 SPDT relay outputs and 3 digital inputs, enabling isolated control of external field devices such as alarms, relays, and contactors.

Q2: Can this card be used as a standalone module?
A: No. The AR C093 AE01 is an option board that must be plugged into the RMIO interface board of an ABB ACS800 drive (SLOT 1 or SLOT 2). It cannot operate independently and requires the host drive for power and control.

Q3: What is the contact rating of the relay outputs?
A: Each relay is rated for 250 V AC / 5 A (resistive load) with a maximum switching capacity of 1250 VA. For inductive loads, derating or external suppression is recommended.

Q4: How is the module configured?
A: Configuration is performed in two steps: (1) On-board DIP switches assign the function of each relay and DI channel; (2) Drive parameters are set using DriveWindow or Drive Composer software to activate and map the functions.

Q5: What are the digital input voltage specifications?
A: The 3 digital inputs support 24 V DC (19–30 V) or 110–230 V AC/DC, with optical isolation. The DI2-DI3 pair has 1.5 kV isolation between them, while the overall DI/DO/power isolation is 2.5 kV AC.

Q6: What should I check if a relay output fails to operate?
A: Verify that the drive parameters have been configured to activate the corresponding relay. Check the DIP switch settings match the intended function assignment. Inspect the field wiring to the Common, NO, and NC terminals. If the relay is commanded but does not switch, the relay may have reached end-of-life—replace the card.

Choosing the Right Model

• For ACS800 drives needing additional relay outputs: The AR C093 AE01 is the correct option board, providing 2 SPDT relays and 3 digital inputs in a single plug-in module.

• For additional digital I/O without relays: Consider the RDIO-01 extension board if relay capability is not required.

• For system verification: Always confirm the host drive is an ACS800 series with an available RMIO slot, and verify DIP switch settings match the intended application before installation.
