Exd [ ia ]

Exd [ ia ]

(OP)
We have a transmitter(slg 720) installed in a zone 1. it has a hazardous area rating of Exd[ia] it also has a 4-20ma output. We want to change this signal into enraf bpm so we are installing a converter in a switchroom which is a safe area,this is also rated Exd [ia].my question is does the cable between the two have to be an intrinsically safe cable?

thanks

RE: Exd [ ia ]

No. The "ia" bit refers to the electronic device in the Exd housing so for cabling follow Exd rules and not intrinsically safe. Seems OTT to have an Exd housing in a safe area by the way...
