ABB P8891 relay output module

Product manual:

P8891 is a relay output module widely used in industrial automation
In the fields of building control and energy management, it is used to control the on/off operation of external devices.
The following is a detailed introduction to the P8891 relay output module:
Product Overview
Main functions:
The P8891 module controls the on/off status of external devices through built-in relays, providing isolation and switching operations between low-power control signals and high-power loads.
Design features:
High reliability relay, supporting multiple switching operations.
Electrical isolation design protects the control system from the effects of high voltage and overload.
Compact modular structure, easy to install in standard racks or control cabinets.
