Main features and advantages

The Potter&Brumfield SDAS-01-7Y2S1024 AC current sensor relay provides significant advantages in current monitoring applications due to its unique design and functionality.Its core features are zero insertion loss and inductive coupling technology.This means that the relay does not require any physical connection(such as series connection)on the power line,but rather detects the current non invasively through induction,thereby avoiding power loss and complex wiring,and improving the safety and reliability of the system.

This module provides two adjustable sensing modes,overcurrent and undercurrent.Through simple potentiometer settings,users can flexibly configure the current threshold according to specific application needs.This makes it widely applicable in various monitoring scenarios,such as motor overload protection or equipment operation status monitoring.The built-in solid-state sensing circuit ensures high precision and fast response,while the internal DPDT relay contacts provide reliable switching capabilities that can directly drive control circuits or alarm indicators.

SDAS-01-7Y2S1024 has a built-in time delay function,which can effectively filter transient currents or surge currents during motor start-up during overcurrent and undercurrent detection,prevent misoperation,and improve system stability.Its compact size,socket installation method,and sturdy plastic dust cover design make it easy to install and integrate into various control panels and industrial environments.

Installation and maintenance

Preparation before installation:

Before installing the Potter&Brumfield SDAS-01-7Y2S1024 module,it is essential to ensure that the relevant power circuits have been completely disconnected and all necessary safety measures have been taken to prevent electric shock.Please carefully read the installation manual and data sheet provided with the relay to understand the detailed wiring diagram,installation method,and environmental specifications.

Choose installation location:As it is a socket installation,it is necessary to ensure that a compatible 10 pin socket(such as KUP series)has been correctly installed in the control cabinet.

Power cord threading:Thread the AC power cord that needs to be monitored through the sensing hole in the center of the SDAS-01 relay.Do not confuse it with the control power supply of the relay.

Electrical connection:According to the wiring diagram,correctly connect the 24 VAC/DC control power supply to the corresponding pins of the relay.At the same time,connect the DPDT output contacts of the relay to your control circuit,alarm system,or PLC input.

Setting adjustment:Adjust the set point(threshold)of the current sensing through the potentiometer on the relay according to the application requirements.If it is overcurrent mode,set an upper limit value;If it is undercurrent mode,set a lower limit value.

Maintenance suggestion:

The Potter&Brumfield SDAS-01-7Y2S1024 module is typically designed as a maintenance free product.However,to ensure its long-term stable operation,it is recommended to conduct the following checks regularly:

Visual inspection:Regularly inspect the appearance of the relay to ensure that there is no dust accumulation,physical damage,or loose connections.Keep the surrounding environment clean and dry.

Functional testing:Conduct regular functional testing based on the application situation,such as adjusting the monitored current or relay set point to verify its overcurrent/undercurrent detection function and contact output for normal operation.

Environmental control:Ensure that the working environment where the relay is located meets its temperature and humidity specifications,avoiding extreme temperatures,high humidity,or corrosive gases.

Contact inspection:Although it is an internal relay,if any abnormalities occur after long-term operation,the output contacts can be checked for aging or erosion(if it can be safely disassembled for inspection).
