60 Dimensions of HART communication resistor, engineering unit: mm (in)
A communication resistor is required for HART communication. If this is not already present
(e.g. in the power supply RMA, RN221N, RNS221, ...), it can be ordered with the device via the
product structure, feature 620 "Accessories enclosed": option R6 "HART communication resistor
hazardous / non-hazardous area".
Alternatively, it is available as an accessory; order number "RK01-BC"
Alternatively available as an accessory, for details see Technical Information TI01043K and
Operating Instructions BA01170K
The HART communication resistor is specially designed for use with the RIA15 and can be attached
easily.
