Description

Features

Analog inputs

• 8 single-ended/4 differential channels or 16 single-ended/8 differential channels
• 12-bit resolution
• Data transfer rate for one channel: 125 kHz
• Input ranges: 0-10 V, ±10 V, 0-5 V, ±5 V selectable through jumper, 0(4)-20 mA optional (options DC and SC)
• Gain INA (instrumentation amplifier), adjustable through jumper or resistance
• Addressing through DIP switches
• 3 x 16-bit timer (82C54): Timer 0: only for the analog acquisition; Timer 1 and Timer 2 : as cyclic time-counters

Analog acquisition

• One single channel, several channels, several channels through scan list
• Automatic analog acquisition through cyclic timer control
• Acquisition through scan list: up to 16 entries with gain, channel, unipolar/bipolar
• Acquisition triggered through software, timer, external event
• Trigger functions: Software trigger or external trigger: the analog acquisition (single or sequence) is started through external TTL signal switching from 0 to 5 V at TTL input
• Interrupt: end of single channel, end of multichannel, end of scan list

Digital

• 2 digital open collector outputs

Safety features
