EOL - IndustryPack with 48 TTL Level Tristate Digital I/O Lines
Product phased out. Please call systerra for replacement options.

IP-DIO48-ET is an IndustryPack compatible module providing 48 digital TTL tri-state I/O lines with pull up resistors. Each of the 48 I/O lines is ESD protected and protected against overvoltage.

The line inputs are always enabled, allows determining the state of the I/O line at any time. This can be used as read back function for lines configured as outputs.

All 48 input lines can generate an interrupt. Each input interrupt can individually be enabled and cleared. Interrupts for negative and positive transitions could be used together with separate interrupt pending registers. All interrupt inputs have an electronic debounce circuit to prevent short spikes on input lines to cause an IP interrupt.

Optional the I/O lines can be configured for simultaneous update internally and across several IPs by an external clock source. The polarity of the external clock source is programmable.

Six resistor networks mounted in sockets are used to pull the tri-state I/O lines to a logic high value. The resistor networks can be removed or changed in value.

After power-on or reset all I/O lines are configured as input and all pending interrupts are cleared.
