Page 6 - 426/10/2001AutoLog 32 Instruction Manual6.3.3 Optoelectronic / relay isolation of inputs and outputsSince the inputs and outputs of the AL 32 series are not isolated, it is advisable toprovide external isolation in an environment prone to disturbances. A suitablesolution is the use of PHOENIX digital optical input interface modules and relayoutput modules. The Modules protect the PLC against the static discharges and cutthe circulating fault currents. The modules are mechanically fully protected DIN railunits.Features of the I/O modules: very long life optoelectronic isolation rated at 2500 V low power consumption vibration proofPHOENIX’s digital I/O modulestype I/O voltage max. current logic voltageDEK-OE-24DCDEK-OE-230ACDEK-REL-24/1/SEN24 ± 20% VDC230 ± 10% VAC12 - 250 VAC10 - 125 VDC3 A24 V24 V24 V24 VOE modules are input modules and REL modules are relay output modules.PHOENIX modules: DEK-OE input module and DEK-REL type output moduleFF-Automation Oy
