GuardPLC 1600 Controller
GuardPLC 1800 Controller
The GuardPLC 1600 system features 20 digital inputs and 8 digital
outputs with the addition of optional distributed Safety I/O. The
GuardPLC 1800 system features 24 digital inputs, 8 digital outputs, 8
safety-related analog inputs, and 2 high-speed counters, as well as
optional distributed Safety I/O. The status of inputs and outputs is
indicated via status indicators. A user-supplied 24V DC power supply
is required. See page
45 for information on power supply
requirements.
Each controller features four 10/100BaseT, RJ-45 connectors to
provide safety-related communication via the GuardPLC Ethernet
network to distributed I/O and other GuardPLC controllers, OLE for
Process Control (OPC) servers
(1)
, and with RSLogix Guard PLUS!
programming software. The four connectors and the controller are
connected via an internal Ethernet switch.
