PSS(1) DIO T

Overview

The DIO T Module provides 16 digital inputs and 16 digital outputs. The
outputs can be used as pulsed outputs or as single-pole 2 A outputs.
Input signals must show a "High"of 24 V DC (+15 ... +30 V DC) and a
"Low" of 0 V DC (-3 ... +5 V DC). The inputs have a filter and are
galvanically isolated through an optocoupler.
Outputs are protected against short-circuit, over-load and excess
temperature. They can switch both resistive and inductive loads. Outputs
are isolated through an optocoupler.
The code for the PSS(1) DIO T Module in the Data Block DB002 is
8001 8012.
The PSS DIO T module is designed for use on the Series PSS 3000
module Rack. The PSS1 DIO T module is designed for use on the Series
PSS 3100 Module Rack.
The PSS(1) DIO T module provides test pulses for the test signal. It can
only be used for single-pole 2 A outputs, if all of the outputs are not being
used for signals.

Functions

Inputs

Input status is transmitted to the CPU via the 3-channel parallel Bus (Mo-
dule Rack). There the status appears as "0"-Signals ("Low") or "1"-Signals
("High") which are processed according to the application software. The
status of the inputs is displayed through LEDs, which light as soon as a
"1"-Signal is present at the relevant input.
Diagnostic circuitry checks the function of the inputs, with the exception of
the input filter and the optocoupler. If an error occurs, the controller goes
into the STOP condition, switches off and sends a message to the CPU
display.

Outputs

The outputs are push-pull outputs, which may be configured in an 8-matrix
as pulsed outputs or single-pole 2 A outputs. If the CPU sends a "1"-
Signal via the parallel Bus, the DIO T will supply 24 V DC to the relevant
2
