Electrical connections
The module is designed for spring cage clamp
electrical connections.

There are three ways to power the DSCP6x series of signal converters.
1. Connect the 24VDC power supply directly to terminals 7 (+) and 8 (-)
of each module.
2. Connect power to one signal converter and use the expandable Power-
Bus connector to distribute power to a maximum of 16 adjacent modules.
The bus can be supplied from any of the modules, but the total current
consumption of the bus must be less than 400mA. Higher consumption
values can damage the module. An appropriately sized fuse must be
connected in series with the power supply.
3. Use the DSCP70 Power Supply Connection Module and the expandable
Power-Bus connector to distribute power to a maximum of 75 modules.
The DSCP70 is designed to protect the modules connected via bus against
overvoltage loads. The bus connector can be provided with power using the
DSCP70 module if the total consumption of the bus is less than 1.5A. Higher
consumption values can damage both the module and the bus. An appropri-
ately sized fuse must be connected in series with the power supply.
