Terminal Layout; Digital Outputs A1 To A4 - Honeywell FE260 Operating Instructions Manual

FE260

3.3.2 Terminal layout


With an EK260 or EK280 volume corrector, set "TypS2" = "2" before you connect it to
the FE260 in order to avoid damage to the devices.
FE260
„DC" version only
On the EK260 and EK280 the terminals "R+", "R-", "T+" and "T-" are also labelled with "CS", "RD", "RS" and
"TD". When connecting the FE260, these designations have no significance. The terminals "Ri" and "Gnd" on
the EK260 remain unconnected.
The cable designations (Cable 1 and Cable 2) and the suggested core colours are based on the use of two
similar cables, LiYCY 4 x 2 x 0.5 mm², twin-twisted with colour code according to DIN 47100. Suitable cables
can also be obtained from Elster-Instromet (see II-2, Options).
With "AC" versions (with 230V or 115V power supply) the blue and red wires of Cable 1 remained unused.
They should then be cut off at both ends flush with the cable sheath or safely insulated to prevent hazardous
short circuits from forming.
Of course, other cables can also be used provided they conform to the requirements quoted in 0. Similarly, a
different designation of the core colours is possible.

3.4 Digital Outputs A1 to A4

The terminals "A1" to "A4" are individually electrically isolated digital outputs which pass on the incoming
signals on "DA1" to "DA4" (pulse or message signals) from the volume corrector unmodified with respect to
time. Due to the approved electrical isolation, any devices without Ex approval can be connected to A1 to A4,
provided they do not exceed the limits quoted in the chapter "Technical Data".
