1 for electrically insulating, amplifying and converting DC signals, also designed for FSK 002 II () G pplication The purpose of the isolating amplifi er SIRX TV 808 (Fig. ) is to electrically insulate input and output signals, respectively to amplify and/or change the signal level or type (current or voltage) of the input signals. The instrument version SIRX type 808- has an intrinsically safe and an FSK continuity function and is used to control smart I/P valve positioner in explosion hazard areas. The valve positioner adjust, for example, a pressure or the position of a valve in relation to the impressed output current ( 20 m). The RT bypass permits bi-directional FSK signals to pass according to the RT protocol. green LD on the front plate indicates device standing by. The power supply and the inputs and outputs are electrically insulated. Fig.. Plug-in module SIRX TV 808 for plugging onto backplane BP 902. Variants and non-x isolating amplifiers Designed or not designed for FSK communication User-specific input ranges Power supply 2 0 V DC/C or V DC/C Features / Benefits Isolating amplifi er plugs onto backplane (mechanically latched by fasterners), all electrical connections made to the backplane and not to the SIRX TV 808 / Thus no wiring when replacing devices Designed for FSK communication, hand-held terminal connected to separate terminals. This facilitates operation in conjunction with a smart I/P valve positioner designed for FSK and with a RT or userspecific protocol lectric insulation between input, output (2.3 kv) and power supply (3.7 kv) / Prevents measurement errors due to potential leakage Burden voltage 20 V for not x versions or V for x instruments Non-standard user-specific ranges available C/DC power supply / Universal vailable in type of protection Intrinsic safety [x ia] IIC (see Table 3: Data on explosion protection ) Technical data Measuring input DC current: DC voltage: FSK = Frequency Shift Keying Standard range 20 m Limit value 0 0. to 0 0 m also live-zero, to m max. span: 0 m also bipolar asymmetrical R i = Ω Limit values to 0 0 also live-zero, to V, max. span: 0 V R i = 00 kω Camille Bauer Data sheet TV 808-//7/8 Le 0.09

4 Compatibility Most of the usual smart valve positioners (current-to-pneumatic converter) on the market with IS approval are compatible with the intrinsically safe output of the TV 808 (see Table ). On inquiry, we will verify if other valve positioners can be used.
