Chapter 4 Digital Modules

4.2 SM-DOUT1

4.2.1 Introduction

The SM-DOUT1 provides eight optoisolated 24V DC (typ.) digital outputs

arranged in 2 independent groups. The maximum output switching fre-

quency is limited to 1 kHz (square wave) with the output in the ON state

when the system issues a logical ‘0’. The maximum continuous output

supply current is limited to 500mA (resistive loads) and provision has been

made to cater for inductive loads. The user interface is realized by 8 yellow

LEDs (1 per output channel) which illuminate when the output is ON.
