Pelco PA30-0065-00-A1 PTZ Decoder Module

The Pelco PA30-0065-00-A1 is a PTZ decoder module designed for analog surveillance systems. It acts as the interface unit between a Pelco matrix or keyboard controller and a pan‑tilt‑zoom camera. The module decodes Pelco‑D or Pelco‑P protocol commands received over an RS‑485 serial link and converts them into relay outputs for pan/tilt motor control and lens action (focus, zoom), allowing precise camera positioning from a remote control center.

Decoder Functionality

The module receives Pelco‑D or Pelco‑P commands from a master controller (e.g., Pelco matrix or keyboard) over RS‑485. It interprets the commands and energises the appropriate output relays to drive the camera’s pan and tilt motors, as well as the zoom and focus functions of a motorised lens. An auxiliary relay can be used to control external devices such as wipers, heaters or infrared illuminators. The decoder can be configured for auto scan mode, where it continuously moves the camera between two preset boundaries.

Installation and Configuration

The PA30-0065-00-A1 is a PCB‑level module that is typically installed inside a protective camera housing or control cabinet. A DIP switch or dial sets the camera address (0‑255) and baud rate. The module is powered by a 24 V AC security supply. The RS‑485 bus must be correctly terminated and shielded to ensure reliable long‑distance communication. The decoder automatically detects the Pelco‑D or Pelco‑P protocol, but can also be manually fixed.

Application Domains

This decoder module is used in analog CCTV systems for highway surveillance, power plants, ports, and large commercial buildings. Its wide temperature range and optional IP66 protection make it suitable for both indoor and outdoor installations in extreme climates.
