OMX-CJC-C ENCAPSULATED COLD JUNCTION COMPENSATION

DESCRIPTION

The OMX-CJC-C is the identical circuit used on the OM5-BP backpanels except it is packaged as a component for use in customer designed mounting boards (Figure 24). When interfaced to an OM5-ITC or OM5-LTC module, the transfer function of the voltage across the +SEN and –SEN pins is VCJC = 0.510 –0.0025(T –25)V.

OMX-1344 JUMPERS

DESCRIPTION

Package of 10 jumpers for connecting adjacent input/output modules on the OM5-BP-16-C backpanel. This connection is made if it is desired to direct the output of any input module to the input of an adjacent output module. The jumpers can also be used for configuring I/O addresses on the OM5-BP- 16-MUX-C backpanel.

OMX1362-C CURRENT CONVERSION RESISTOR

DESCRIPTION

A precision 20Ω, 0.1%, 10ppm/°C resistor used with the OM5-II current input module or OM5-TX two-wire transmitter interface module (Figure 25). Sockets are provided on all backpanels to allow installation of this resistor. One OMX-1362-C is shipped with each module.
