AC2521 - Electronic module IFM - Free user manual and instructions

USER MANUAL AC2521 IFM

• Current measurement 0 ... 20 mA

• AS-i profile S-7.3.6

• The sensors are connected via M12 connection cables

• Time for converting the measured values in the slave: < 1 ms

• Actuator supply from external 24 V PELV voltage source (black flat cable, max. 1.1 A in total)

• Resolution: 1 µA Installation / Addressing When you use module lower parts without addressing socket (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 (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 0.8 Nm. 7Electrical connection The analogue module is connected to the AS-Interface via the E-EMS (supply from an ext. 24 V PELV voltage source). If the supply is to be from an external 24 V source, a FC-E lower part (art. no. AC5003 or AC5011) must be used. As an alternative FC-E lower parts with earthing lead (AC5021, AC5023) can be used to increase the noise immunity.

2Operation Check the safe functioning of the unit. Display by LEDs:

• LED yellow AO1...AO4 on: analogue signal in the measuring rangeor no actuator connected. It cannot be differentiated whether the 0 V signal is applied or whether an actuator is con- nected

• LED yellow AO1...AO4 flashes: analogue signal outside the measuring range (outside range)

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

• LED green AUX on: external 24 V 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. Measuring range of the analogue input modules The measuring ranges, the states of the LEDs and their meaning are indicated in the following tables: Analogue output module 0 ... 20 mA
