Electrical connections
Screw terminals:
Max. 1.0 mm
2
(AWG 17) for options
Max. 2.5 mm
2
(AWG 14) for
4 ... 20 mA input signal
IMPORTANT (NOTE)
Do not expose the terminals to strain.
Four thread combinations for cable entry and pneumatic
connection
- Cable: thread 1/2-14NPT, air pipe: thread 1/4-18 NPT
- Cable: thread M20 x 1,5, air pipe: thread 1/4-18 NPT
- Cable: thread M20 x 1,5, air pipe: thread G 1/4
- Cable: thread G 1/2, air pipe: thread Rc 1/4
(Optional: With cable gland(s) and pipe plugs if necessary)

Any
9.1.8 Safety Integrity Level
IMPORTANT (NOTE)
Applies to applications with single-acting and depressurizing
pneumatics.
The positioner TZIDC / TZIDC-200 and the emergency shutdown
module for meet the requirements regarding:
- functional safety acc. to IEC 61508
- explosion protection (depending on the model)
- electromagnetic compatibility in accordance with EN 61000
Without the input signal, the pneumatic module in the positioner vents
the drive and the installed spring in it moves the valve in a
predetermined end position (OPEN or CLOSED).
