The TSA-623PST is an intelligent Pressure Switch (dual relay), Transmitter and Display all in one.
It uses an advanced ARM industrial-grade MCU at its core for a fast response, combined with a high quality pressure sensor element.
It can be used for industrial pressure control in pumps, hydraulics and pneumatic equipment.
The TSA-623PST can simultaneously process and display pressure on its 4 digit LED display, switch the relay contact setpoint (set via membrane keys), and transmit a 4-20mA analog output signal.
By default the A1 relay triggers on a rising pressure, and the A2 relay triggers on a falling pressure.
