4.1 POWER OPTIONS
The Con TROLL PRO process controller module is available with two power
options:
• DC-powered, which requires a 9-36 VDC supply as the primary power
source. This model can trigger low voltage (<50 V) relays only (see “Input/
Output Connections” on page 23).
• AC-powered, which requires a 100-240 VAC as the primary power
source. This model can trigger low voltage relays (<50 V) through the I/O
board only (see “Input/Output Connections” on page 23) and high voltage
relays (>50 V) through the AC board only.
4.2 ELECTRO-STATIC DISCHARGE (ESD) RECOMMENDATIONS
• Before making wiring connections, discharge any static electricity from
your body before touching circuit boards and other internal components
by touching a grounded metal object to remove any charge from your
body.
• When making wiring connections, make sure to remain properly grounded
by wearing an ESD wrist strap or similar device.
