AC2526 - Electronic module IFM - Free user manual and instructions

USER MANUAL AC2526 IFM

• Current measurement 4 ... 20mA

• AS-i profile S-7.3.E

• The sensors are connected via M12 connection cables

current measurement < 50Ω

• Time for converting the measured values in the slave - for one channel: 20ms - for two channels: 120ms - for three channels: 180ms - for four channels: 240ms

• Sensor supply from AS-i (max. 100mA) or external 24V PELV voltage source (black flat cable, max. 500 mA)

• Resolution: 1µA Installation / Addressing When you use module lower parts without addressing socket (AC5000, AC5001 or AC5003) first address the module by placing it onto an addressing unit (AC1144) and assign a free address between 1 and 31. When you use module lower parts with an addressing socket (AC5010 or AC5011) the modules can be addressed with the addressing adapter E70213 later on. Mount the module onto the wired module lower part of the AS-i net- work, tightening torque 0.8Nm. As an alternative FC/FC-E lower parts with earthing lead (AC5020...AC5023) can be used to increase the noise immunity. SEITE 8Electrical connection The analogue module is connected to the AS-Interface via the stan- dardised EMS (supply from AS-i) or the E-EMS (supply from an ext. 24V PELV voltage source). If the supply is to be from an external 24V source, a FC-E lower part (art. no. AC5003 or AC5011) must be used. If a total of over 100mA is needed for the sensor supply, the sup- ply must be from an external 24V PELV voltage source. The supply is automatically changed when the external 24V vol- tage is supplied. SEITE 9

• LED yellow AI-1...AI off: no sensor connected (at least one LED flashes because not all channels can be deactivated via the para- meter bit P1/P2 (channel activation))

• LED yellow AI-1...AI-4 on:analogue signal in the measuring range

• LED yellow AI-1...AI-4 analogue signal outside the measuring - flashes: range or no sensor connected

• LED green PWR on: AS-i voltage is applied

• LED green AUX on: external 24V voltage is applied

• LED red FAULT on: AS-i communication error

• LED red FAULT flashes: periphery fault*

• periphery fault A periphery fault is indicated:

• if at least one of the analogue signals is outside the value range.

• if nothing is connected to at least one analogue channel although the respective channel is activated PAGE 11 Parameter bit Designation Description
