Product Overview
Thirty-two-channel SCXI input modules take their field wiring through a front-mount terminal block, and the SCXI-1300 is the general-purpose one. It has 72 screw terminals: 32 pairs for the module's 32 differential inputs, plus chassis ground, OUTPUT, AOREF and GUARD, with a cold-junction temperature sensor on the board.
Key Features
- 72 screw terminals, channels silkscreened CH0 to CH31
- Onboard cold-junction sensor, LM35CAZ, 10 mV per degree C
- CHSGND, AOREF, OUTPUT and GUARD terminals
- W1 jumper position marked MTEMP and DTEMP on the board
- Board marking: SCXI-1300 REV.A ASSY181575-01
- NI part number 777687-00 for the SCXI-1300
Applications
- Re-terminating thermocouples on an SCXI-1102 or SCXI-1100 module, using the onboard sensor for cold-junction compensation
- Swapping out a cracked or corroded terminal block in a working SCXI rack
- Holding a spare for a 32-channel input slot on an older NI acquisition system
Frequently Asked Questions
Which modules does it fit?
32-channel SCXI modules: the SCXI-1100, SCXI-1102/B/C and SCXI-1104/C.
Does it have the cold-junction sensor for thermocouples?
Yes. The SCXI-1300 carries an LM35CAZ sensor that outputs 10 mV per degree C.
Is this an SCXI-1300 or the 50-terminal SCXI-1302?
SCXI-1300. Its terminals are labeled by channel, CH0 through CH31, and the label reads PART NO 185161A-01. The SCXI-1302 numbers 50 terminals 1 to 50 and has no channel labels.
Is it sold as a pull, untested since it came out of service?
Yes. It was working when removed from service and was not tested afterward. You get the terminal block alone, no cables, and take on the first check: meter a few channels to the rear connector before trusting a full rack to it. Flat-rate shipping in the lower 48, and orders over the free-shipping line ship free.
Its board still names every channel, CH0 through CH31, in silkscreen dated 1991. Read those labels against your old wiring list and re-terminating gets a lot simpler.
