The “Iso OK” contact can be evaluated via a PLC. This status is maintained until the next measurement interval. Operation with Grounded Control Circuit (Functional Potential Equalization) <ul><li>The module establishes an internal connection between the 0 V (X2.2) and ground (X2.1) connections via a semiconductor switch.</li><li>At 10 s intervals, the connection between 0 V and ground is interrupted for 0.5 s, and the isolation resistance between +24 V (X1.3) or 0 V (X2.2) of the supply voltage and earth (X2.1) is determined.</li><li>The grounding connection on the module does not meet the requirements of a protective earth terminal (PE). It serves as a functional ground. The measurement method does not involve the module establishing any permanent connection bet-ween 0 V and ground.</li></ul> Operation with Ungrounded Control Circuit <ul><li>In this operating mode, the semiconductor switch to establish a connection between 0 V (X2.2) and ground (X2.1) is deactivated. At 1 s intervals, the isolation resistance offset is determined for 0.5 s.</li><li>The module does not meet the requirements of an isolation monitoring device per EN 61557-8.</li></ul> “Iso OK” Contact <ul><li>The potential-free contact serves the purpose of supporting evaluation (e.g., via a PLC) of looming isolation faults.</li><li>This contact must not be used to switch safety-related products that could cause the circuit to switch off.</li></ul>", "mpn" : "789-665", "sku" : "789-665", "brand" : { "@type":"Brand", "name":"WAGO" }, "manufacturer" : { "@type":"Organization", "name":"WAGO Kontakttechnik GmbH & Co.
