Any application with a back-up battery connected has to be calculated in order to define the actual backup time.A typical application with a RTU without I/O Expansion module, otherexternal equipment connected to the 24VDC power supply will have an current consumption of about 300mA at 24VDC battery backup supply. It will typically a backup time of 6hours on a battery with a capacity of 3Ah. Counter input Two 32 bit counters is provided on counter input 0 and 1. The counters can be used for S0 input, only via potential free contacts. The counters values are battery backed, when power is off.The...

RTU calls CS/Active Dial up RTU can be configured for active call up. RTU calls CS if an event of priority 1 occurs (RTU870: change of single or double indication or if active dial back is enabled and activated). If a priority event occurs, RTU870 calls CS. RTU870 starts to call the first telephone number in the number list. If connection to CS is not established the RTU870 will wait the Redial delay time and try again. That will go on the number of Retry counts defined. If the dial attempt still fail under the number of retries, the RTU870 use the next subscriber no on the phone no list. If...

Boot Delay Ensure that master boot is not started until the I/O bus is fully up running. In case of several analogue I/O modules connected you may encrease this value in sec. S0 Cnt Type Define the counter type. Absolute values or acumulated values is possible. S0 Interval Define the length of the time between counter values is tranfered to the IEC870-5-101 queue. Values from 1min to 240min is posssible, however the selected value has to dividable into 1 day (24hours). Analog Range Select the analogue input range; 0-20mA or 4-20mA. Note that underflow alarm is only valid in range 4-20mA. METER...

Compact Utility Outstation with 24IO and serial ports RTU870 > 16)N/A17)The sum of current consumed from the 12V rail, i.e. internalconsumption, consumption from the external screw terminals and by expansion modules at the local bus, must never exceed the maximum total output current.18) The external output is short circuit protected and overload pro-tected. The maximum current is limited at high ambient tempera ture. The maximum load current should be de-rated approximately 1% per C above 25аC.19)N/A20)The counter frequency is reduced when the module is heavilyloaded, see counter section. Brodersen...

Modem requirement The modems used must support even parity. This can be a problem for some (older) modems. When using GSM communication the master (CS) must implement long timeout delays for retransmission, 10 sec or more. This is due to large delays on the GSM net. > Serial RS232 COM interfaceRS232 port (9 pole sub-D) The RTU870 keeps the state dial requestӔ until all information, which is marked for transmission, is transmitted CS calls RTU870 . If the link is disconnectedbefore all data is transferred (i.e. by the CS) RTU870 tries to dial the CS after a predefined time e.g. 10 min.CS is responsible...
