Switching amplifiers

Switching amplifier for Namur sensors according to 94/9/EG (ATEX)

NAMUR switching amplifiers evaluate the sensor signal and control the output. They meet all requirements of the ATEX directives. Switching amplifiers with relay and active transistor and potential-free optocoupler outputs are available. The control circuits hold the approval Ex II (1) GD [EEx ia] IIC. The amplifiers are designed for the connection to NAMUR sensors according to DIN EN 60947-5-6 and mechanical switches. They provide the supply voltage for the intrinsically safe circuit.

Switching amplifiers

The one or two-channel switching amplifiers are equipped with transformer and switched-mode power supplies for AC input voltages and provide a regulated 24 V DC output voltage (up to max. 200 mA) for the supply of sensors. The sensor signals are returned to an input and trigger an output relay without delay that allows switching of AC voltages up to 230 V. One version is equipped with timer functions that can influence the switching of the output relay.
