Warning:

ç

Use National Electric (NEC) or other
country-specific standard wiring and
safety practices when wiring and
connecting this controller to a power
source and to electrical sensors or pe-
ripheral devices. Failure to do so may
result in damage to equipment and
property, and/or injury or loss of life.

Note:

Maximum wire size termination
and torque rating:
• 0.0507 to 3.30 mm

2

(30 to 12

AWG) single-wire termination
or two 1.31 mm

2

(16 AWG)

• 0.8 Nm (7.0 in-lb.) torque

Note:

Adjacent terminals may be la-
beled differently, depending on
the model number.

Note:

To prevent damage to the con-
troller, do not connect wires to
unused terminals.

Note:

Maintain electrical isolation
between digital input-outputs,
switched dc/open collector out-
puts and process outputs to

prevent ground loops.

Note:

If the last two digits of the part
number are "12", this Equip-
ment is suitable for use in
CLASS I, DIVISION 2, Groups
A, B, C and D or Non-Hazard-
ous locations only. Temperature

Code T4

Warning:

ç

Explosion Hazard – Substitution of
component may impair suitability for
CLASS I, DIVISION 2.

Warning:

ç

Explosion Hazard - Do not disconnect
while the circuit is live or unless the
area is known to be free of ignitable
concentrations of flammable sub-
stances.

Note:

Each of the four SSR outputs has internal circuitry that will protect it from over

heating. Outputs may be disabled (shut off) automatically if internal temperatures

exceed those listed in the graph above. After the output temperature drops approxi-
mately 10 °C the outputs will once again be enabled for operation.
