The RS485MS-2W is required to enable the Modbus communications function on Model 77x-type products. This module is required when the RM-1000, RM-2000 or other Modbus capable device is used with 77x-type products.
The CIO-MB / CIO-120-MB Modules are convenient and cost-effective Modbus-RTU interfaces capable of providing discrete control and monitoring of an overload relay over a Modbus network.
The CIO-DN-P / CIO-120-DN-P
are convenient and cost-effective Devicenet interfaces capable of providing discrete control and monitoring of motor starters, drives and other devices over a Devicenet network.
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 CIO-EN Module (non-POE) is a convenient and cost-effective Modbus-TCP and Modbus-RTU interface capable of providing discrete control and monitoring of an overload relay over a Modbus network.
The Com 4-20mA Output Module is intended for use with ONLY the Model 777-AccuPower output power monitor. The module will send a 4-20mA signal proportion-al to the output power. It can also be used to send the input power by setting the efficiency setting on the 777-AccuPower monitor to one. This module allows communication to a PLC with an analog input and no Modbus input.
