Warning:
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 elec-
trical sensors or peripheral
devices. Failure to do so may
result in damage to equip-
ment and property, and/or
injury or loss of life.
Note:
Maximum wire size termina-
tion and torque rating:
• 0.0507 to 3.30 mm2 (30 to
12 AWG) single-wire termi-
nation or two 1.31 mm2 (16
AWG)
• 0.8 Nm (7.0 lb.-in.) torque
Note:
Adjacent terminals may be
labeled differently, depend-
ing on the model number.
Note:
To prevent damage to the
controller, do not connect
wires to unused terminals.
Note:
Maintain electrical isolation
between analog input 1, digi-
tal input-outputs, switched
dc/open collector outputs and
process outputs to prevent
ground loops.
Note:
The control output common
terminal and the digital com-
mon terminal are referenced
to different voltages and
must remain isolated.

A network using Watlow's Standard Bus
and an RUI/Gateway.
A network using Modbus RTU.
Wiring a Serial EIA-485 Network
Do not route network wires with pow-
er wires. Connect network wires in
daisy-chain fashion when connecting
multiple devices in a network.
A termination resistor may be re-
quired. Place a 120 Ω resistor across
T+/R+ and T-/R- of the last controller
on a network.
Only one protocol per port is avail-
able at a time: either Modbus RTU or
Standard Bus.

EtherNet/IP™ and Modbus TCP communica-
tions to connect with a 10/100 switch.
• Do not route network
wires with power
wires.
• Connect one Ethernet
cable per controller to
a 10/100 mbps ether-
net switch. Both Mod-
bus TCP and Ether-
Net/IP™ are available
on the network.
• A RUI may be con-
nected at the same
time using Slot C.
Note:
Avoid continuous writes
within loops. Excessive
writes to EEPROM will cause
premature EEPROM failure.
The EEPROM is rated for
1,000,000 writes.
