Digital Inputs (24 V AC/DC, 120 V AC, 230 V AC, 48 V DC) PN: 750-400...415

Technical description

The supply is applied by a series-connected termination to each I/O module for the respective operating voltage. Power connections are made automatically from module to module when snapped onto the DIN rail.

Attention:

The lowest power jumper contact is not carried out for some modules (e.g. 4-channel)! A module which needs all contacts (e.g. 2 channel digital) may not be connected to the right hand side of modules which do not have 3 power jumper contacts (e.g. 4 channel modules).

All 2-channel digital inputs are 4-conductor devices allowing the direct connection of 4- conductor sensors with the terminations V+, 0V, ground and signal.

The 4-channel digital inputs are suitable for the direct connection of two 3-conductor sensors (V+, 0V, signal). The power distribution module 750-614 is available for the connection of more sensors to V+ and 0V.

The modules 750-408 and 750-409 are low-side switching.

A 2-wire proximity switch can be connected to the modules 750-410 and 750-411. RC filters are series-connected to the 5, 24 and 48 V versions for noise rejection and switch debouncing. They are available with time constants of 3.0 ms and 0.2 ms.

The standard numerical assignment for bus operations is from left to right, starting with the LSB. The positions of the different I/O modules in the configured node/station are selectable by the user. A block type configuration is not necessary.

The Input module can be connected to all buscouplers of the WAGOÇI/OÇSYSTEM.
