Description

Features

8 digital inputs, 24 V, isolated

• 2 connection lines per input
• Parallel acquisition of digital 24 V signals
• Each input channel has its own ground line

8 digital outputs, 24 V, isolated

• Each output channel can be triggered independently from the others
• The output channels are current-limited and suitable for loads with high inductive currents
• 2 diagnostic outputs generate LOW level at overtemperature
• Watchdog: can be activated through software, readable
• After power-on the outputs are reset to “0”
• Addressing through DIP switches

Safety features

• Optical isolation 1000 V
• Voltage supervision
• Creeping distance IEC 61010-1 (VDE411-1)
• Safety for the inputs: voltage reversal protection, LC filters
• Safety for the outputs: Overtemperature protection: Shut-down logic at approx. 125-140 °C, short-circuit current at 1.5 A, Shut-down logic, when the external supply voltage drops below 5 V.
• Safety features for the ext. supply voltage: overload protection: self-resetting fuse (electronic fuse), overvoltage protection through varistors and transorb diodes, screened through LC filters

EMC tested according to 89/336/EEC (CE certification)

• IEC 61326: electrical equipment for measurement, control and laboratory use

Applications

• Industrial I/O control
• Automatic test equipment
• Interface to electromechanical relays
• Monitoring of 24 V signals
• Activation of alarm
• Signal switching
• ON/OFF monitoring of motors, lights…
• Machine interface
