Description

Features

32 digital outputs, 24 V, isolated

• Output current: 500 mA
• Voltage range: 10 to 36 V
• Diagnostic reports, readable through status register in case of short-circuit, overtemperature, voltage drop or watchdog
• 3 x 16-bit timer (82C54): Timer as programmable watchdog for the reset of the outputs to “0”, function release through software, control of 2 output channels for generating square-wave signals
• Interrupt triggered through error on the outputs or through timer2
• Addressing through DIP switches
• 16-bit or 8-bit data bus
• After power-on the outputs are reset to “0”

Safety features

• Optical isolation 1000 V
• Creeping distance IEC 61010-1 (VDE411-1)
• Protection against fast transients (burst), overvoltage, electrostatic discharge and high-frequency EMI
• Maximum output current for 32 output channels: 6 A typ. (2 x 3 A)
• Self resetting fuse (electronic fuse)
• Short-circuit current per output 1.5 A typ
• Output capacitors minimise electromagnetic emissions
• Fast demagnetization in case of inductive loads
• External 24 V supply screened through a Protective circuitry

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

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

Applications
