PLC Street Light Controller NEMA Type

Nema standard PLC single Light controller

1. Product description

1.1 Introduction

    The WE-MA-P10 intelligent single lamp controller (hereinafter referred to as the single

 lamp controller) is developed using a high-performance single-chip hardware platform

 and combined with power line carrier communication technology to realize street

 lamp telemetry, remote signaling, and remote control functions.

     The single-lamp controller is with functions of voltage/current acquisition, 

PWM (0~10V) output, and street lamp switch control. Under the premise of ensuring 

the correct connection, it can work normally without any setting operations.

1.2 Standard

• Extended communication protocol according to "DL/T 645-2007 Multi-function Electric Energy Meter Communication Protocol"

• "Master station unified platform information collection system communication protocol: master station and collection terminal communication protocol v1.0"

• "Smart Energy Meter and Collection Terminal Event Record Collection and Reporting Rules.pdf"

• "Event Reporting Process.pdf" in the Power User Electricity Information Collection System

2. Installation size

    The external size of the single-lamp controller is 84mm×84 mm×106mm, which is 

mounted on the street lamp head with Nema standard interface by rotation, as shown 

in Figure 2-1.

3. Terminal definition

   The main body of the single lamp controller terminal is divided into two types, one is 

the strong current terminal, the other is the weak current terminal, there are 7 pins

connected to the outside, the middle 3 pins are the strong current interface, one of 

which is the N line and the others are the L Line in, L line out. The 4 pins on the side are

0~10V and PWM dimming output. The controller realizes the control function of the 

street lights through the live wire of the control loop. To ensure the safety of the 

operators, it is recommended not to install with electricity. The bottom view of the 

controller is shown in 3-1.

4. Function description

    The single lamp controller has functions such as voltage/current acquisition, PWM 

/(0~10V) output, and street lamp switch control.The specific parameter configuration

 is shown in Table 4-1.
