Electrical data
Signal circuit
(terminal +11 / -12)
Contact input
(terminal +81 / -82)
Switch output
(terminal +83 / -84)
The following modules may be operated with the TZIDC as an option:
Plug-in module for digital position feedback
(terminal +51 / -52 or +41 / -42)
Plug-in module for analog position feedback
(terminal +31 / -32)
Plug-in module for shutdown contact input
(terminal +51 / -52 or +85 / -86)
Mechanical digital feedback
(terminal limit1 +51 / -52 or limit2 +41 / -42)
Special conditions
• Devices may only be connected to circuits in zone 2 if they are suitable for operation in zone
2 potentially explosive atmospheres and for the conditions prevailing at the installation
location (manufacturer's declaration or certificate from an inspection authority).
• For the "digital feedback with proximity switches" circuit, external measures must be
implemented to prevent the rated voltage from being exceeded by more than 40 % in the
event of transient disturbances.
• It is only permissible to connect, disconnect, and switch live circuits during installation or
maintenance, or for the purpose of carrying out repairs. Comment: It is considered very
unlikely that a potentially explosive atmosphere would be present in zone 2 at the same time
that installation or maintenance/repair work was being carried out.
• Only non-flammable gases may be used for the pneumatic auxiliary power.
• Only use suitable cable entries which meet the requirements of IEC 60079-15.
• If the SJ2_S1N (NO) proximity switch is used, the positioner may only be operated at an
ambient temperature range from -25 ... 85 °C.
