Analog acquisition

• Single channel, multi-channel, multi-channel through sequence list
• Automatic analog acquisition through cyclic timer control
• Acquisition through sequence 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 signal switching from 0 V to 24 V at the digital input 0.
• Interrupt: end of single channel, end of multichannel, end of scan list

Analog outputs

• 8 analog outputs, optically isolated (500 V)
• Voltage outputs
• 16-bit resolution (15-bit for 0-10 V)
• Output range: ± 10 V, 0-10 V (switchable through software)
• Output voltage after reset: 0 V
• Each output has its own ground line (without optical isolation)
• Output current ± 5 mA max. for voltage outputs
• EMI filters

Digital

• 4 dig. inputs including 1 interruptible input
• 4 dig. outputs, 24 V, optically isolated

TTL I/O

• 24 digital TTL inputs/outputs
