Description

UNS0881a-P,V1 3BHB006338R0001 ABB

1. Module Overview

The ABB UNS0881a-P,V1 3BHB006338R0001 is a high-reliability digital input module designed for industrial automation systems. It supports multiple signal types (e.g., switch inputs, pulses) and features a HART interface for parameter configuration and diagnostics^^.

2. Installation & Wiring

2.1 Mechanical Installation

Mount on DIN rail (EN 60715 compliant) with a torque of 0.6 Nm for terminal screws^^.
Ensure ambient conditions: -25°C to +55°C, ≤95% RH non-condensing^^.

2.2 Electrical Connections

Terminal	Function	Specification
DI1-DI8	Digital inputs	24V DC (19.2-30V range)
HART	Configuration interface	4-20 mA with HART protocol
PWR	Power supply	24V DC ±10%

Warning: Use shielded cables (CY type) and ground at one end to minimize EMI^^.

3. Parameter Configuration

3.1 HART Interface Setup

Connect a HART communicator to the designated port.
Default parameters:
[HART_Config] Device_ID = Factory_Set Poll_Address = Auto Update_Rate = 1Hz
For Fieldbus integration (PROFIBUS PA/Foundation Fieldbus), use Softing commModule tools^^.

3.2 Input Signal Calibration

Power on the module and wait for the PWR LED (green) to stabilize.
Apply a test signal to DI1; verify response time ≤35ms^^.
Adjust thresholds via HART commands:
WRITE "DI1_High", 22.5mA WRITE "DI1_Low", 3.5mA
