Description
FlexTop 2211 is a 4...20 mA loop-powered, configurable universal
transmitter with galvanic isolation between input and output. The input
can be configured for RTD or T/C sensors, resistance, current or
voltage signals.
Either 2-, 3- or 4-wire connection can be selected for the resistance
input. The built-in temperature sensor or a remote Pt100 sensor can
be used to compensate for "cold junction" (CJC) if thermocouples are
connected.

Design and specifications subject to change without notice
FlexTop 2211 is embedded in silicone which makes it resistant to humid
environments.
The configuration can be established from the dedicated FlexProgrammer
configuring tool connected to a PC.
FlexTop 2211 has a 6 mm center hole for fast sensor replacement and
spring loaded mounting screws which ensure a safe fastening even in
vibrating environments.
