subsequently.
Note 2 : Depending on the Model, SP1 and SP2 may be fitted with any of three output
types, RLY , SSd or Analogue (Specification on page 11/12) where appropriate,
these must be allocated during initial configuration. SP3 is always fitted with RLY .

Re-transmission
* These models above offer the option of using the analogue output for Re-transmission .
Select
bAnd
or
bnd.2
value in
LEVL 1
to equal the full range setting in
LEVL A
and if
using SP1 output, set
int.t
and
dErt.t
in
LEVL 1
to off.
Example: Set-Up using a Model 95B11P to Re-transmit the 4-20 mA input, scaled 0 to 100
units. SP1 relay is used as the control output and SP2 analogue output is used for re-
transmission.
Note : Read in conjunction with Linear Input Set-up Procedure on page 6.
