When wire-break or short-circuit monitoring are activated, mechanical contacts can only be connected with a corresponding resistor circuitry (WM1, Ident no. 0912101). The module features protection class Ex ib IIC and can be mounted in zone 1 in combination with excom®. The explosion protection cate- gory of the inputs is Ex ia IIC. The inputs are galvanically isolated from each other. The behavior of the inputs can be adjusted via the Fieldbus master. The following parameters can be adjusted: switching behavior, switch- on delay, default value, wire-break and short circuit monitoring. ■ Input module for intrinsically safe sensors ■ Complete galvanic isolation
