Q1
EXMFE4 input board:
-
Two pulse or message inputs [EEx ib] IIC. When being used as pulse input,
the board is suitable for the connection of LF and HF pulse generators
similar to DIN 19234, with max. 10 kHz; automatic level adaptation by
channel. The first channel is also suitable for the connection of an encoder
totalizer.
-
Temperature sensor input for a PT100 in 4-wire technique; [EEx ib] IIC;
maximum measuring error in a range of -10 to +60°C and 0 to 40°C
ambient temperature: ± 0.05 % of the measurement.
-
Measuring sensor input from 4 to 20 mA; [EEx ib] IIC; maximum measuring
error in a range of 4 to 20 mA and 0 to 40°C ambient temperature:
± 0.05 % of the measurement.
This channel can alternatively be used for the connection of up to 4
measuring sensors with HART interface (multi-drop).
MFA6 output board:
-
One relay output (break contact, max. 28.8 V at 120 mA).
-
Three transistor outputs (max. 28.8 V DC at 90 mA) for messages or
pulses max. 25 Hz.
-
Two analogue
outputs 0/4 … 20 mA for measurements; max. load
impedance: 300 ohms. Error in a range of 4 to 20 mA and 0 to 40°C
ambient temperature: ± 0.1 % of the output value.
LMFA7 output board:
-
Fibre-optics connection for external I/O expansion. The
gas-lab
Q1 needs
this fibre-optics connection for the connection of the sensor technology.
-
One relay output (break contact, max. 28.8 V at 120 mA).
-
Two transistor outputs (max. 28.8 V DC at 90 mA) for messages or pulses
with max. 25 Hz.
-
Four analogue
outputs 0/4…20mA.
