AC/DC Inputs, Relay Outputs & Isolation Groups

Eight flexible field inputs and eight isolated normally open relay channels.

System role

DX571 combines one group of 24 V AC/DC inputs with two groups of normally open relay outputs for mixed-voltage machine and panel switching duties.

AC or DC sensing All eight inputs accept the documented 24 V AC or 24 V DC field signal within one isolated input group.
Dry relay switching Eight normally open relay contacts switch external load circuits and do not behave like protected transistor sourcing outputs.
Three isolation groups The input group, two relay-output groups and the rest of the module are galvanically separated as documented.
Visible channel state Separate yellow LEDs indicate each input and relay-output command state for commissioning and troubleshooting.

Relay Protection, Terminal Blocks & Service Limits

Relay applications require load-specific fusing and suppression, the correct 9-pin and 11-pin terminal blocks and recognition that DX571 is not an approved hot-swap module.

01
External output protectionProvide the documented external fuse or circuit breaker for each relay load; the contacts are not internally short-circuit protected.
02
Inductive DC loadsConnect a free-wheeling diode across inductive DC loads to control demagnetization energy.
03
Inductive AC loadsProvide external spark suppression sized for the driven AC load and its switching characteristics.
04
Terminal-block familiesABB lists TA563 screw side-wiring, TA564 screw front-wiring and TA565 spring front-wiring terminal blocks in 9-pin and 11-pin sizes.
05
Hot-swap restrictionABB's current hot-swap table states that DX571 does not support powered exchange.
06
Active lifecycleDX571 and the listed terminal blocks are Active; no successor is required for lifecycle reasons.

Buyer Questions for ABB DX571

AC/DC input use, relay-load limits, protection, terminal accessories and service handling.

Q01

Can ABB DX571 read both 24 V AC and 24 V DC input signals?

Yes. ABB specifies eight digital inputs for 24 V AC or 24 V DC, arranged as one galvanically isolated group.

Q02

Which load voltages can the eight ABB DX571 relay outputs switch?

ABB specifies normally open relay outputs for 24 V DC, 24 V AC or 100–240 V AC loads, with a maximum 2 A rating under the documented conditions.

Q03

Are ABB DX571 relay outputs internally protected against a short circuit?

No. Provide external fuses or circuit breakers and load-appropriate suppression. Inductive DC loads require a parallel free-wheeling diode; inductive AC loads require external spark suppression.

Q04

Which removable terminal blocks are ordered for ABB DX571?

ABB lists TA563, TA564 and TA565 terminal blocks in 9-pin and 11-pin versions, covering screw or spring connections and different cable directions.

Q05

Can ABB DX571 be removed under power from a hot-swap terminal unit?

No. ABB's hot-swap compatibility table states that DX571 does not support hot swap. Isolate power and follow the hardware manual before module exchange.

Q06

Which load details are required to quote ABB DX571 correctly?

Send order code 1TNE968902R2302, input supply type, each relay load voltage/current and category, terminal-block preference, controller, quantity, destination and delivery date.

Transaction Cases

Sincere Cooperation, Long-Term Trust

RussiaCASE 01

A Russian customer urgently needed a replacement for a discontinued automation component. After reviewing the product label, technical parameters, and application details, our engineers recommended a compatible alternative and provided photos and test videos before shipment. The alternative performed well, enhancing the customer's confidence in our technical capabilities and leading to multiple repeat orders.

IndiaCASE 02

An Indian customer still had doubts after initial online communication with us, so they visited our company in person for a face-to-face meeting and product inspection. This visit increased the customer's trust and led to the successful placement of their first order. Over the next few years, we completed multiple orders and established a stable, long-term partnership.

VenezuelaCASE 03

A Venezuelan customer needed a specific automation component and compared products and services from several suppliers online. After nearly three weeks of careful consideration, our sincere communication, professional service, and reliable product quality won the customer's trust. After receiving the product and using it for several weeks without any problems, the customer gave us positive feedback and subsequently placed multiple orders.
