PRODUCT DESCRIPTION

The testing of the semiconductors that is necessary from a safety point of view results in what are known as

OSSD low phases in many products. The effect of this is that when an output is active (high state), a switch-off

situation (low state) occurs for a very brief amount of time. The test can be cut off if this behavior leads to problems

in the application. Observe the associated safety-related notices!

X20SO4120 B

The modules are equipped with 2 or 4 safe digital outputs. The nominal output current is 0.5 or 2 A.

The modules can be used for controlling actuators in safety-related applications up to PL e or SIL 3.

The outputs are designed using semiconductor technology so that the safety-related characteristics do not depend

on the number of switching cycles. The "high-side low-side" variant (output type A) is limited to actuators without

reference potential (e.g. relays, valves). Type A outputs have safety-related advantages since the actuator can

be cut off in its connection cable in all error scenarios. Safe digital output modules are equipped with protection

against automatic restart in the event of network errors as well as current measurement for open-circuit detection.

These modules are designed for X20 12-pin terminal blocks.

• 2 or 4 safe digital outputs with 0.5 or 2 A

• Source circuit

• Output type A

• Current monitoring

• Open-circuit detection

• Integrated output protection

The module is equipped with safe digital output channels. It can be flexibly used for controlling actuators in safety-related

 applications up to PL e or SIL 3.

The outputs are designed using semiconductor technology so that the safety-related characteristics do not depend

on the number of operating cycles. In order to handle all situations involving actuators, there are basically 2 different

 types of outputs: the high-side - low-side variant (type A) and the high-side - high-side variant (type B).

Type A outputs have safety-related advantages since the actuator can be cut off in its connection cable in all error

scenarios. Type A outputs are limited to actuators without ground potential (e.g. relays, valves). For actuators with

ground potential (e.g. enable inputs on frequency inverters), type B outputs are required. It is important to observe

the special notices for the cabling in this case.

Safe digital output channels provide protection against automatic restart when network errors occur. Function

blocks needed to fulfill additional requirements regarding protection against automatic restart are available in

SafeDESIGNER. The outputs can also be controlled by the standard application. The combination of safety-related

control and standard control is arranged such that the execution of a cutoff request always has top priority. For

diagnostic purposes, the outputs are designed to be read back.

Depending on the product, the safe digital output channels are equipped with current measurement for detecting

open circuits. This function can also be used to monitor muting lamps, for example.
