Device Description

The I/O module 750-527 (4DO 30V AC/DC 2.0A SSR) acts together with the
MOFSET transistors to switch voltages up to 30 VAC or 48 VDC (for resistive
loads).
The semiconductor switches attached to the CAGE CLAMP
substitute for relay contacts. Because of their wear resistance, application
availability is increased.
The I/O module has 4 output channels, providing a direct connection to 2-wire
actuators.
The actuators are connected to the following CAGE CLAMP
or DO 2, DO 3 or DO 4 and 0 V.
The assignment of the connections is described in the "Connectors" section.
Although the semiconductor outputs are not continuously protected against short
circuit, they are highly resistant against pulse currents, so an external switched
fuse is promptly tripped in case of short circuit.
In addition to a suitable fuse, the output transistor withstands brief overcurrents
until switch-off without damage.
Connection examples are shown in section "Connect Devices" > ... >
"Connection Example(s)".
A green LED indicates the switched status of each channel.
The meaning of the LEDs is described in the "Display Elements" section.
Use supply modules for ground (earth)!
The I/O module has no power jumper contacts for receiving and transmitting the
earth potential. Use a supply module when an earth potential is needed for the
subsequent I/O modules.
The I/O module 750-527 (4DO 30V AC/DC 2.0A SSR) receives the power supply
of up to 30 VAC (or 48 VDC for resistive loads) via the power jumper contacts
designed as blade contacts from an upstream power supply and provides it to
downstream I/O modules via the power jumper contacts designed as spring
contacts.
