GuardPLC 1200 Controllers
Introduction
Power Supply Connections Power supply connections for GuardPLC 1600, GuardPLC 1800, and
GuardPLC 1200 controllers are described in the following sections.
GuardPLC 1600 and GuardPLC 1800 Controllers
The supply voltage is connected via a 4-pin connector that
accommodates wire sizes up to 2.5 mm
2
(14 AWG). You only need to
connect one wire to L+ and one wire to L-. Both L+ and L- terminals
are internally connected. The other terminal can be used to
daisy-chain 24V DC to additional devices. The power supply
connector is rated to 10 A.
