Jumo 00543005 Input module RS-485 1 pc(s)

The wireless receiver is used together with suitable transmitters for mobile or stationary measurement of physical parameters. Through the use of trend-setting wireless technology of the industrial radio frequency 868.4 MHz a significant reduction in the installation effort results. There is no need for cable connections, the radio-based sensor technology also works in harsh industrial environments. The supplied lambda/4 antenna with an impedance of 50 Ohm can be mounted directly onto the wall or externally. If the optional antenna wall bracket is used with a 3 m long antenna line, the free-field range is 300 m. The measured values received from the transmitter are transformed and indicated in the receiver and are available as linear current or voltage signals (0(4) to 20 mA, 0 to 10 V) and via digital RS485. All vir analogue outputs of the receiver are electrically isolated. Via the digital interface with Modbus protocol, it is possible to connect to higher-level systems, for example to system visualization software or Modbus master-compatible screen recorders. The operation and configuration is possible via the keyboard along with a two-line LCD display or more comfortable by a setup program. For each channel, parameters such as filter constants, offset, alarms and drag pointers (minimum and maximum value memory) can be set separately. For this purpose, there is a plug for a PC interface with TTL/RS232 or USB/TTL converter for connection between the receiver and the PC on the front. The receiver in the mounting rail casing is designed for mounting on a DIN rail 35 × 7.5 mm according to DIN EN 60715. The screw terminals for the electrical connection are arranged in different levels. The cable cross-section must not exceed 2.5 mm2. The power supply is connected to AC/DC 20 to 30 V, 48 to 63 Hz.
