The below table describes the function of the connectors on the back side of the Controller backplane.

IO Chassis for non-redundant IO modules (Safety Manager)

The IOCHAS-0003S is a chassis for up to 18 non-redundant IO modules. It consists of the following components:

The above figure shows the front side of an empty IOCHAS-0003S with the front-cover raised. A 19″ chassis has 21 slots for modules (each 4TE wide). These slots are numbered 1 to 21, starting at the lefthand side of the chassis.

In the IOCHAS-0003S, slots 1 to 18 are available for IO modules.

IO Housing

The IO housing is specifically designed for Safety Manager.

It is a 19″ based housing.

A coverplate assembly at the front of the chassis shields the flatcables of the IO modules. This cover can be swung upwards to access the flatcables. To swing the cover upwards, unlock it by moving the two locking slides horizontally towards the middle of the chassis. The backside of the IO cover assembly provides room for a tagnumber assignment drawing.

The backside of the IO housing is covered by an IO back cover plate that can be removed by rotating the half-turn locking screw anti-clockwise (see the below figure).

IO cable clamp support (with tie wrap) at the back of the IO housing leads all cables towards the side of the IO chassis.

Figure 6-49 shows a front view of a filled IOCHAS-0003S with the cover closed.

The below table lists the connectors present on the IOBUS-HBS.

The pin allocation of each respective input and output module can be found in the module datasheet.

Figure 6-54 shows the pin mapping from an IO chassis connector at the front to both a SIC cable (CNx) connector and a converter (Px) connector at the back of the IO Chassis.

General info about power supplies

Power supplies are used to convert different V AC input voltages to a specific V DC output voltage, which is used by Safety Manager.

The below table shows all suitable power supplies and their input and output voltages.

Power supplies and their input and output voltages

Power supply Input feeder Output feeder

PSU-UNI2450 110-240 V AC 24 V DC, 50 A

PSU-UNI4825U 110-240 V AC 48 V DC, 25 A

PSU-UNI6020U 110-240 V AC 60 V DC, 20 A

PSU-UNI11011U 110-240 V AC 110 V DC, 11 A

The below table also shows the available power feeders required to process DC plant power. They can be wired identical to the power supplies.

FEEDER-48R 48 V DC 48 V DC, 63 A

In addition to these, Power Supply Unit PSU-240516 is located in the Controller chassis. It is described in the chapter about Control Processor modules, in section PSU-240516.

Non-redundant power supply units (N configuration)

In this configuration the number of PSUs chosen matches the required power. If the system has a nonredundant Controller there may be no need for redundancy in the PSU configuration.

AC power feeders supply the power for the entire Safety Manager system. To limit the load on the feeder, you are advised to put no more than 2 power supplies on one feeder.

This configuration has the following characteristics:

The PSU(s) deliver(s) sufficient power for Safety Manager.

A failure in one of the PSUs may lead to a system stop with undefined results.

A failure in the mains power leads to a system stop with undefined results

See “Power Supply Units configurations (2 examples for each configuration)” on the facing page for details.
