The input module DI401-EX is used for the

connection of NAMUR sensors (DIN EN

60947-5-6) or mechanical contacts.

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 category 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, switchon delay, default value, wire-break and short

circuit monitoring.
