USER MANUAL AC2611 IFM

• Minimum load resistance voltage measurement > 10kΩ

• Time for converting the measured value in the slave < 28ms

• Actuator supply via the AS-i network (internal max. 60mA, 24V ±20%) or external supply 24V ±20%; PELV

• Resolution of the analog values in steps of 6, 9, 12, 15 bits

• No calibration required by the user

Do not use free locations.Mounting Mount the module onto a 35mm rail or fasten it onto a mounting device (accessories required E70119). Electrical connection The actuator must always be ungrounded! If an external potential is used, it must be a PELV voltage. The electrical separation to the AS-i system is rated for 500V. Links may only be inserted or removed with the system being dis- connected.

After an interference individual values can be transferred incor- rectly. This can be avoided by a double transmission of the out- put values. To do so, set the parameter bit P3 to 0. PAGE 10 COM

• setting upon request PELV supply without ground connection internal linkAddressing Connect the addressing unit to the terminals A+ and A- by means of a cable plug. Remove the addressing plug and assign a free address between 1 and 31 (factory setting is 0). Pin connection of a cable plug: 1 = A+/brown, 3 = A-/blue Leave the addressing plug removed. Operation The data transmission/representation of the measured value in the host is controlled by the user program. In conjunction with the controller the evaluation is performed by a corresponding function block (AC0314). (If other masters are used, function blocks for the protocol 7.1 are needed).
