Only plug in next to I/O modules with the same field supply! The 750-527 I/O Module can be supplied with up to 30 VAC (or up to DC 48 V for resistive loads) through the power jumper contacts. Thus, this I/O module can only be mounted to I/O modules that are equipped for a field power supply of the same type.
Device Description WAGO-I/O-SYSTEM 750 750-527 4DO 30V AC/DC 2.0A SSR Connectors 3.2.1 Data Contacts/Local Bus Communication between the fieldbus coupler/controller and the I/O modules as well as the system supply of the I/O modules is carried out via the local bus. The contacting for the local bus consists of 6 data contacts, which are available as self-cleaning gold spring contacts.
The blade contacts are sharp-edged. Handle the I/O module carefully to prevent injury. Do not touch the blade contacts. The I/O module 750-527 has 2 self-cleaning power jumper contacts that supply and transmit power for the field side. The contacts on the left side of the I/O module are designed as blade contacts and those on the right side as spring contacts.

WAGO-I/O-SYSTEM 750 Mounting 750-527 4DO 30V AC/DC 2.0A SSR Mounting Do not work when devices are energized! High voltage can cause electric shock or burns. Switch off all power to the device prior to performing any installation, repair or maintenance work.
Always plug a bus end module (750-600) onto the end of the fieldbus node! You must always use a bus end module at all fieldbus nodes with WAGO I/O SYSTEM 750 fieldbus couplers or controllers to guarantee proper data transfer.
WAGO-I/O-SYSTEM 750 Mounting 750-527 4DO 30V AC/DC 2.0A SSR Figure 7: Inserting I/O Module (Example) Press the I/O module into the assembly until the I/O module snaps into the carrier rail. Figure 8: Snap the I/O Module into Place (Example) Check that the I/O module is seated securely on the carrier rail and in the assembly.

Power Supply for AC Voltage (up to 30 VAC) or DC Voltage above 31.2 V (up to 48 VDC) The field-side supply ( load voltage) 750-527 I/O Module for AC voltage ranges (up to 30 VAC) or DC voltage above 31.2 VDC must be supplied by, e.g., through supply module 0 to 230 VAC/VDC (750-612).
Page 36
When these voltages (VAC or > 31.2 VDC) are used, it may be necessary to plan for an in-house supply segment for the following I/O modules. Do not mount any I/O modules behind the I/O module (750-527) that is rated only up to a field-side 31.2°VDC. Therefore, no filter modules (750-626) can be used.
