The CIO-777-PR Module is a convenient and cost-effective Profibus interface capable of providing
discrete control and monitoring of motor starters, drives, and other devices over a Profibus network.
The design of the CIO-777-PR provides the following benefits in both new and existing installations:
reduced field wiring
greater operator efficiency
ease in system startup and commissioning
The CIO-777-PR Profibus module can be DIN rail mounted, or mounted directly to a back panel. The
CIO-777-PR's compact size, ease of wiring and Profibus communications capability makes the use
of traditional discrete devices on Profibus cost-effective and simple.
The CIO-777-PR Module is compatible with SymCom's Model 777-P Series overload relays. It simply
connects to the side of the 777-P Series and permits remote monitoring and control of the 777-P
Series unit over a Profibus network.
CONNECTIONS
1. Mount the CIO-777-PR in a convenient location in a properly rated enclosure. The CIO-777-PR
can be mounted to a back panel using screws or can be snapped onto DIN rail.
2. Connect the five Profibus wires to the 5-pin connector on the front of the CIO-777-PR Module.
24VDC should be connected to V+ and V-. Connect the other three wires to A, B and Shield.
3. The PBus LED indicates that communication is established between the CIO-777-PR and the
Profibus master, and OLC LED indicates communication is established with the 777-P Series
overload.
4. Connect the Profibus SUB-D connector to the Profibus network.
