3.6 Description of options
3.6.1

NAMUR terminal strip (option B00)

The NAMUR command source is a terminal strip that is equipped with isolation amplifiers and
relays and is located upstream of Terminal Modules TM31 and TM15.
Note
The inputs and outputs assigned to the terminals fulfill PELV (Protective extra-low voltage)
requirements.
The NAMUR terminal strip fulfills the requirements and guidelines of the standards association
for measurement and control technology in the chemical industry (NAMUR recommendation
NE37).
On the NAMUR terminal strip, certain device functions are assigned to fixed terminals. The
fixed assignment between drive signals and the NAMUR terminals represents your
standardized control logic in the device and fulfills the requirements for protective separation.
To monitor the temperature of explosion-protected motors, options for PTC tripping devices
with PTB approval and PT100 for use in hazardous areas are available.
3.6.2

Isolation amplifiers for optional analog inputs (option E86)

This option provides two isolation amplifiers if an additional TM31 Terminal Module is provided
as an extension of the customer interface and the TM31 analog inputs are to be used with a
higher-level control level for communication purposes. Multifunction interface converters with
the following adjustment range are used:
● 0 V to 10 V
● 0 mA to 20 mA
● 4 mA to 20 mA
The range must be set on the isolating transformer.
3.6.3

Isolation amplifiers for optional analog outputs (option E87)

This option provides two isolation amplifiers if an additional TM31 Terminal Module is provided
as an extension of the customer interface and the TM31 analog inputs are to be used with a
higher-level control level for communication purposes. Multifunction interface converters with
the following adjustment range are used:
● 0 V to 10 V
● 0 mA to 20 mA
● 4 mA to 20 mA
The range must be set on the isolating transformer.
