M553-CTXDC Multifunction Transducer DC Measuring with RS485 & relay output

Posted on Posted in Multifunction Transducers

Description

The M553-CTXDC PowerCom is a multifunction dc power transducer, providing RS485 Modbus communication and a pulsed output in a 55mm DIN enclosure.

Application

The M553-CTXDC has a universal power supply which is suitable for AC or DC auxiliary voltages.
The M553-CTXDC covers a wide range of voltage inputs and current inputs. The current input can be up to 5 amps direct or any value using a mV input
Example: a shunt of 2000A DCwith 50mV output.

Communication

The M553-CTX uses the well established Modbus protocol. This enables remote reading and programming of the M553-CTX using a host computer.

The RS485 network allows up to 32 units to be connected in parallel, enabling them to be used with PC, PLC, RTU, Data loggers and Scada programs.

The PowerCom’s communication port incorporates an auto-configure function which, when connected to an
existing Modbus network, will automatically detect the network’s parameters.

A red LED is provided to indicate that auxiliary power is present, and that the unit is communicating correctly.

Programming

The following can be programmed via the RS485 port: current inputs, voltage input, demand times, asign relay.

Software

MultiView set-up and monitoring software is available free of charge from our web-site: www.hobut.co.uk

Pulsed Output

An optional pulsed output can be ordered. The relay can be assigned to kW.h (import/export), A.h or it can be configured to act as set-point relay in an over, under or window mode.
