i-Snail-S Current Status Switch

ID: 3504_0
The i-Snail-S closes an electrical switch when currents greater than 0.15A are detected in the wire that passes through its window.

The i-Snail-S switch provides an accurate and cost effective method of monitoring the on/off status of electric loads including fans, pumps, motors, heaters and virtually any AC powered device.


The i-Snail-S serves as an ultra sensitive Go/No-Go load sensor. The dry contact relay (N.O.) closes when a minimum amount (150mA) of AC current is flowing through its monitored line. The device is ideal for monitoring the running state of fans, motors, pumps, heaters or any device that is AC powered, including large and small loads.


The output is a bi-directional solid state relay with a low turn on resistance of less than 4 ohms. The output may be interfaced to PLCs, DDC panels or other relays. The advanced hysteresis and transient detection circuitry prevent chattering and false switching due to line spikes and transients.


The i-Snail-S features a rugged enclosure with integrated barrier strip terminal block for easy wiring in the field.


Note: The i-Snail Current Status Switch measures the current in a single AC wire (either the positive or the negative). If you put the whole cable through the window the + and - wires will cancel each other out and the sensor will read a null current value.
