SN 2301.1
Evaluation electronics 230 V AC ATEX certification group II, cat. (1)G, PTB 01 ATEX 2075
With amplifier for connection of ex flow sensors
with relay output for air flow and line
monitoring. The setting of the threshold value
for gaseous and liquid media is done by slide
controls and potentiometers. The current state is
displayed by a 11-digit LED display. The sensor
and power supply circuit are galvanically
isolated from each other. The evaluation
electronics and the connecting line is monitored
for wire breakage and short-circuit. If the value
falls below the threshold or in the event of wire
breakage or short-circuit, the accompanying
monitoring relay drops out. Breaking capacity of
the relay contacts: 4 A/250 V AC Housing with
click-in base for installation on mounting rail.
Protection class: IP 40 Dimensions: 45 x 78 x 120
