Design and Functional Principle puts respond even when the power supply fails or the electronics are defective. The actuator can also be blocked or driven to its final positions depending on the configuration for example by an external event via a digital input (DI2) on the alarm module. If you require electrically independent limit value messages from the standard controller, you will have to use the SIA module with the slot initiators instead of the alarm module. Communication with the controller is possible via the optional HART interface. 2.2 Instrument Components 14 3 15 2W 3/4 W O 33 90∞ 2 13 4...20 mA 0/4...20 mA 1 DI1 O 90 33∞ 4 12 6.1 6.2 11 10 9 8 7 6 5 1 Input: Supply air 7 Silencer 2 Output: Actuating pressure Y1 8 Transmission ratio selector 3 Display 9 Adjusting wheel slip clutch 4 Output: Actuating pressure Y2 *) 10 Terminals options modules 5 Operating keys 12 Dummy plug 6 Restrictor 13 Screw--type cable gland 6.1 Restrictor Y1 14 Terminal plate on cover 6.2 Restrictor Y2 *) 15 Purging air switch *) in double--acting actuators Figure 2-1 View of the positioner in normal version (cover open) 16 SIPART PS2 Manual A5E00074631-03

It also contains the display and the operating keys. In addition, the terminal strips for connecting the options modules are also on the motherboard. The terminals of the standard controller, the J y - and alarm-option module are arranged at the left--hand front edges and offset against each other in staircase form. A module cover protects the modules from being pulled out and prevents incorrect installation. SIPART PS2 Manual A5E00074631-03 17
