ABB 8VZZ000167H1 DO05 16CH Digital Output w/Relay I/O Module

Description

The ABB 8VZZ000167H1 DO05 is a digital output I/O module designed for discrete switching within ABB Symphony Plus and S+ SD I/O control architectures. Operating as a 16-channel digital output module, it provides isolated signal interface capabilities between the DCS controller and field-level actuators, control relays, solenoids, and indicators.

Built around 16 electromechanical relays, the ABB 8VZZ000167H1 DO05 supports configurable Normally Open (NO) or Normally Closed (NC) operation for each channel. The module requires an xBS02-EPD base unit for mounting and field wiring termination. It handles versatile switching duties across diverse AC and DC voltage ranges, providing physical electrical isolation to protect upper-level process control electronics from field transients.

Features

• 16 Independent Channels: Equips systems with 16 discrete digital output relay channels for multi-device process control.
• Electromechanical Switching: Features 16 onboard electromechanical relays supporting selectable NO or NC configuration.
• Broad Load Ratings: Handles multiple load profiles including 3 A at 24 V DC, 1 A at 48 V DC, 250 mA at 125 V DC, and 3 A at 120 V AC.
• Base Plate Integration: Connects seamlessly into the dedicated xBS02-EPD base unit for secure mounting and simplified backplane interfacing.
• Compact Footprint: Engineered in a slim form factor measuring 34 mm in width and weighing 0.295 kg.

Applications

• Actuator & Solenoid Control: Interfacing discrete control commands to motor starters, solenoid valves, and interlock coils.
• Process Plant Automation: Command signaling for alarms, field annunciators, status indicators, and auxiliary power switching.
• Symphony Plus DCS Expansion: Integrating discrete relay output points into ABB S+ SD I/O nodes.

Installation Guidelines

1. Safety Precaution: Disconnect all field voltage supplies and system power to the S+ SD I/O carrier before installing or replacing modules.
2. Base Installation: Ensure the xBS02-EPD base unit is correctly installed and secured to the mounting rail.
3. ESD Protection: Observe anti-static handling precautions during module unpackaging and insertion into the base connector.
4. Module Insertion: Align the 8VZZ000167H1 DO05 module guides with the xBS02-EPD slot and press firmly until fully seated and locked.
5. Field Wiring: Verify that field relay loads do not exceed maximum contact current ratings across specific AC/DC operating voltages (e.g., 3 A at 24 V DC / 120 V AC).

Commissioning Recommendations

1. Contact Configuration Check: Verify that channel relay output configurations (NO/NC) match the operational logic requirements of connected field devices.
2. Insulation & Voltage Checks: Confirm external field supply levels are within nominal operating limits prior to enabling system output circuits.
3. Signal Testing: Force test individual output channels through the Symphony Plus engineering station to verify field coil energization and contact closure.
