OI-RelayHP
==========

Description
-----------

The OI-RelayHP (HP indicating high power) module is a relay module designed to handle mains AC voltage (230VAC) as well as DC voltage (30VDC) with a maximum current rating of up to 6A.
Its versatile configuration and compatibility make it suitable for various applications requiring relay-based switching.

**Key Features:**

* Four Channels: The module features four relay channels, divided into two configurations:
  * Two channels with Normally Open (NO) contacts.
  * Two channels with a combination of Normally Open (NO) and Normally Closed (NC) contacts.
* Compatibility: OI-RelayHP is optimized for handling dry contacts and power applications, making it suitable for a wide range of industrial settings.
* High Power Handling: With its ability to manage mains AC voltage up to 230VAC and currents of up to 6A, the module is capable of handling high-power loads effectively.
* Small Package: Housed in a compact package format known as BOI13, the module offers space-efficient installation. 
  This design enables users to mount up to three modules on a single rail, enhancing scalability and flexibility in system configuration.

.. warning::
  To segregate the primary voltage and logic supply voltages, the OI-RelayHP module lacks a supply pin on the header block. 
  Consequently, it can only be utilized as a slave unit, wherein user code is executed on a Master module, and commands are transmitted via the communication bus.
