This meter uses plug-in type screw terminal connectors
for all input and output connections. The power supply
connections (pins 23 and 24) have a unique plug and
socket outline to prevent cross connection. The main
board uses standard right-angled connectors.
Replacement 2-, 3-, and 4-pin plug connectors are
available (see Accessories on page 16).
Input Signal – Pins 1 to 6
Pins 1 to 6 are reserved for the input signal conditioner.
See the data sheet for the selected input signal conditioner.
Pins 8 to 15 – Relay Output Pins
Pin 8 SP3 NO.
Normally Open 5 Amp Form A.
Pin 9 SP1/3 COM.
Common for SP1 and SP3.
Pin 10 SP1 NC.
Normally Closed 10 Amp Form C.
Pin 11 SP1 NO.
Normally Open 10 Amp Form C.
Pin 12 SP4 NO.
Normally Open 5 Amp Form A.
Pin 13 SP2/4 COM.
Common for SP3 and SP4.
Pin 14 SP2 NC.
Normally Closed 10 Amp Form C.
Pin 15 SP2 NO.
Normally Open 10 Amp Form C.
Pins 17 to 21 – Rear Panel Switches
Pin 17 ANALOG OUTPUT (+).
mA (0 to 20 mA/4 to 20 mA)
or V (0 to 10 V) output is header selectable.
Pin 18 ANALOG OUTPUT (–).
mA (0 to 20 mA/4 to
20 mA) or V (0 to 10 V) output is header selectable.
Pin 19 Programming LOCK.
By connecting the LOCK pin
to the COMMON pin, the meter's programmed
parameters can be viewed but not changed.
Pin 20 COMMON.
To activate the LOCK or DIM functions
from the rear of the meter, the respective pins have
to be connected to the COMMON pin. This pin is
connected to the internal power supply ground.
Pin 21 DIM.
By connecting the display dim (DIM) pin to
the COMMON pin, the display brightness setting
is halved.
Pins 23 and 24 – AC/DC Power Input
Auto-sensing AC/DC power supply. For voltages between
85-265 V AC / 95-370 V DC (PS1) or 18-48 V AC / 10-72 V
DC (PS2).
Pin 23 AC Neutral / –DC.
Neutral power supply line.
Pin 24 AC line / +DC.
Live power supply line.

Note: The sequence of setpoint outputs on meters shipped prior to 2002
was 1-2-3-4. The sequence is now 3-1-4-2, enabling delay on make
(dom) and delay on break (dob) to be used with both Form “C” relays.
