| Relay Support Devices
Cooper offers a variety of devices designed to support or
complete your protective relay application or installation.
MX7-5 Programmable Contact Module
The MX7-5 acts as a mini-PLC that is inter-changeable with
the Edison relay system. Its seven inputs and two front panel pushbuttons can be
interlocked using combinational AND/OR/NOT logic to any combination of its five output
contacts. The status of all inputs, outputs and timers may be accessed via Modbus. Plus,
when in LOCAL mode, the MX7-5 acts as a pass through RS232-RS485 converter for connection
to other Edison relays (or other Modbus devices).

Edison MU30 Measurement Unit
The MU30 provides a full range of metering functions in the
familiar Edison relay hardware, with all measurments available over Modbus and from the
front panel. Measurments include voltages, currents, watts, vars, va, power factor,
frequency, watt-hours, var-hours, va-hours, watt demand, var demand and va-demand. A
pulsed output is also available for energy meters. The MU30 is ideal for use where
separate metering class voltage and current transformers are used.

TP11 Test Plug Set
The TP11 consists of a test lug and special test socket
which provides signal injection and isolation points for 4 currents, 3 voltages, and
auxiliary power supply (pos., neg., and ground). The system can be supplied in a
standalone case, or may be incorporated into dual or 19" rack mount Edison relay
cabinets (provide link to 150-05.pdf).

TR3 Follower Relay
The TR3 provides 3 sets of form c high speed auxiliary
output contact for each of three independent input channels. Each set includes one
magnetically latched relay whose position will not change upon power supply failures.
Response time is <10msec.

RS232 to RS485 Converter
This is a convenient, self powered RS232/RS485 converter
with hardwired PC (RS232) and relay (RS485) cables allowing for simple interconnection to
Edison or Edison Pro relays. Part number PRCPSC.
