8 ï 750-454 [2 AI 4-20 mA, Differential Inputs]DescriptionWAGO-I/O-SYSTEM 750I/O Modules2.1.1.3 DescriptionThe analog input module and its variations receives signals with standardizedvalues of 4-20 mA.The module has two differential input channels and can receive differentialsignals via the connections +AI 1 and -AI 1 or +AI 2 and -AI 2.The input channels of a module have a common ground and a shield (screen)connection (S). The Shield (sreen) is directly connected to the DIN rail. Acapacitive connection is made automatically when snapped onto the DIN rail.The input signal of each channel is electrically isolated and will be transmittedwith a resolution of 12 bits.The operational readiness and trouble-free internal data bus communication ofthe channels are indicated via a green Function LED. Broken wire, overrangeor underflow of the measuring range is indicated via a red error LED.Any configuration of the input modules is possible when designing thefieldbus node. Grouping of module types is not necessary.The voltage supply is done via system voltage.AttentionThis module has no power contacts. For field supply to downstream I/Omodules, a supply module will be needed.The analog input module 750-454 and its variations can be used with allcouplers/controllers of the WAGO-I/O-SYSTEM 750 (except for the economytypes 750-320, -323, -324 and -327).
