Product Overview
Eight Isolated Analog Inputs with Jumper-Set Gain and Filter for an SCXI Chassis
Condition
Used. Appears in good condition on inspection, with some minor marks from use and storage, and was removed from a working system. Visual inspection only. Function testing not performed. Front panel legible: SCXI 1120 and 8 CHANNEL ISOLATION AMPLIFIER. The module pictured is representative.
Selling online since 1999. It ships from our Idaho warehouse the same or next business day.
Product Overview
Eight thermocouple, millivolt, volt or current inputs, each one isolated, feed a single channel of the controlling DAQ device through this SCXI analog input module. Gain is set by jumper on every channel, each channel has its own lowpass filter, and working isolation is 250 Vrms.
Key Features
- 8 isolated input channels, multiplexed into one channel of the DAQ device
- Output range +/-5 V
- Jumper gains of 1, 2, 5, 10, 20, 50, 100, 200, 500, 1000 and 2000
- Lowpass filter on each channel, selectable at 4 Hz or 10 kHz
- 250 Vrms working isolation
- 32-pin DIN C male front connector for a terminal block
- 50-pin male ribbon-cable rear connector
- Thumbscrews at the top and bottom of the front panel
Applications
- Reading thermocouples on a process line with high common-mode voltage, through an SCXI-1320 or SCXI-1328 block
- Swapping a failed SCXI-1120 out of a chassis that still runs its original configuration
- Holding a spare isolated input slot for a legacy NI acquisition rack
Frequently Asked Questions
Which terminal blocks plug onto the front?
The SCXI-1320 and SCXI-1328 screw-terminal blocks. Both carry an onboard temperature sensor and mate with the 32-pin DIN C front connector.
Are gain and filter set from software?
No. Both are set per channel with jumpers on the board, so match them to the module being replaced before it goes in the chassis.
Was this module taken out of a working system and left untested?
Yes. It came out of a working system, shows minor marks from use and storage, and has had visual inspection only. You get the module itself, and take on setting its jumpers and proving each channel in your own chassis. Flat-rate shipping in the lower 48, and orders over the free-shipping line ship free.
The front panel spells out 8 CHANNEL ISOLATION AMPLIFIER in plain capitals, which is the whole job description. Set the jumpers to match the old one and let your chassis be the judge.
